Dow Corning 品牌胶水封装剂双部分室温潮湿愈合类说明书

Information About Dow Corning ® brand Adhesive/SealantsSilicones and ElectronicsLong-term, reliable protection of sensitive circuits and components is important in many of today’s delicate and demanding electronic applications. Silicones function as durable dielectric insulation, as barriers against environmental contaminants and as stress-relieving shock and vibration absorbers over a wide temperature and humidity range.In addition to sustaining their physical and electrical prop-erties over a broad range of operating conditions, silicones are resistant to ozone and ultraviolet degradation, have good chemical stability and are available in a variety of useful forms as conformal coatings, encapsulants and adhesives.Dow Corning’s broad range of general purpose and specialty products offers you a choice of materials for your application needs.Dow Corning offers a variety of noncorrosive silicone products for electronic sealing, bonding and adhering applications. These adhesives generally fall into three cure types. The first group are moisture cure, generally meant for room-temperature processing. The second type(condensation cure) offers rapid room-temperature and deep-section curing. The third type is heat cure for rapid processing. All convert to durable, relatively low stresselastomers. Most will develop good, primerless adhesion to a variety of common substrates including ceramics, reactive metals and filled plastics.TYPICAL PROPERTIESThese values are not intended for use in preparing speciﬁcations.Speciﬁcation Writers: Please obtain copies of the Dow Corning Sales Speciﬁcations for these products and use them as a basis for your speciﬁcations. They may be obtained from any Dow Corning Sales Ofﬁce, or from Dow Corning Customer Service in Midland,MI. Call (517) 496-6000.HEAT CURE TIMESCURE CONDITIONSOne-Part Moisture Cure RTVThe one-part moisture cure adhesives (838, 839, 3165, 3145,3140 and 3-1744) are generally cured at room temperature and in a range of 30 to 80 percent relative humidity. Greater than 90 percent of their full physical properties should be attained within 24 to 72 hours depending on the product chosen. Materials and parts can be handled in much shorter times of about 10 to 120 minutes depending on the product chosen and the amount of material used per part. These materials are not typically used for highly confined or deep section cures. Materials will generally cure about 0.25 inch per seven days from any exposed surface. Cure progresses from the outer surface and is dependent on the moisture in the air. Working time is generally a few minutes to an hour for these products until a surface skin begins to form. Mild heat acceleration of the cure rate may be possible but temperatures above 60°C (140°F) are not recommended.Two-Part Room Temperature Condensation CureDow Corning ® Q3-6093 Silicone Adhesive is the only two-part condensation curing product. Once mixed, cure progresses rapidly at room temperature. Good strength is attained within an hour but full properties are not reached for anumber of days. Q3-6093 adhesive contains its own source of moisture and cure progresses evenly throughout the material.Deep section or confined cures are possible however (see “Reversion”). Working time is only a few minutes.Heat CureThe addition curing adhesives (577, 3-6876, 3-6611 and 3-6265) should be cured at 100°C (212°F) or above. The cure rate is rapidly accelerated with heat (see cure schedulesin table). For thicker sections or if voiding is observed, a 30 minutes pre-cure at 70°C (158°F) may reduce voids in the elastomer. Addition-curing materials contain all the ingredients needed for cure with no byproducts from the cure mechanism. Deep section or confined cures arepossible. Cure progresses evenly throughout the material.These adhesives generally have long working times.PREPARING SURFACESAll surfaces should be thoroughly cleaned and/or degreased with Dow Corning ®brand OS Fluids, naphtha, mineral spirits,methyl ethyl ketone (MEK) or other suitable solvent.Solvents such as acetone or isopropyl alcohol (IPA) do not tend to remove oils well, and any oils remaining on the surface may interfere with adhesion. Light surface abrasion is recommended whenever possible, because it promotes good cleaning and increases the surface area for bonding. A final surface wipe with acetone or IPA is also useful.Different cleaning techniques may give better results than others. Users should determine the best techniques for their applications.ADHESIONDow Corning silicone adhesives are specially formulated to provide unprimed adhesion to many reactive metals,ceramics and glass, as well as to selected laminates, resins and plastics. However, good adhesion cannot be expected on nonreactive metal substrates or non-reactive plastic surfaces such as Teflon ®, polyethylene or polypropylene. Special surface treatments such as chemical etching or plasma treatment can sometimes provide a reactive surface and promote adhesion to these types of substrates. Dow Corning ®brand primers (see “Primer Selection Guide”) can be used to increase the chemical activity on difficult substrates.2P5200 Red is a low-VOC alternative to 1200 Red.3P5204 is a low-VOC alternative to 1204.4The lower VOC value is for states and air quality management districts that have recognized volatile methylsiloxanes as VOC exempt.PRIMER SELECTION GUIDEThese values are not intended for use in preparing specifications.Poor adhesion may be experienced on plastic or rubber substrates that are highly plasticized, because the mobile plasticizers act as release agents. Small-scale laboratory evaluation of all substrates is recommended before production trials are made.In general, increasing the cure temperature and/or cure time will improve the ultimate adhesion.SUBSTRATE TESTINGDue to the wide variety of substrate types and differences in substrate surface conditions, general statements on adhesion and bond strength are impossible. To ensure maximum bond strength on a particular substrate, 100 percent cohesive failure of the adhesive in a lap shear or similar adhesive strength test is desired. This ensures compatibility of the adhesive with the substrate being considered. Also,this test can be used to determine minimum cure time or can detect the presence of surface contaminants such as mold release agents, oils, greases and oxide films.USEFUL TEMPERATURE RANGESFor most uses, silicone elastomers should be operational over a temperature range of -45 to 200°C (-49 to 392°F) for long periods of time. However, at both the low and high temperature ends of the spectrum, behavior of the materials and performance in particular applications can become more complex and require additional considerations.For low-temperature performance, thermal cycling to conditions such as -55°C (-67°F) may be possible, butperformance should be verified for your parts or assemblies.Factors that may influence performance are configuration and stress sensitivity of components, cooling rates and hold times, and prior temperature history.At the high-temperture end, the durability of the cured silicone elastomer is time and temperature dependent. As expected, the higher the temperature, the shorter the time the material will remain useable.COMPATIBILITYCertain materials, chemicals, curing agents and plasticizers can inhibit the cure of addition cure adhesives. Most notable of these include:•Organotin and other organometallic compounds •Silicone rubber containing organotin catalyst •Sulfur, polysulfides, polysulfones or other sulfur-containing materials•Amines, urethanes or amine-containing materials •Unsaturated hydrocarbon plasticizers •Some solder flux residuesIf a substrate or material is questionable with respect to potentially causing inhibition of cure, it is recommended that a small scale compatibility test be run to ascertain suitability in a given application. The presence of liquid or uncured product at the interface between the questionable substrate and the cured gel indicates incompatibility and inhibition of cure.MIXING AND DE-AIRINGUpon standing, some filler may settle to the bottom of the liquid containers after several weeks. To ensure a uniform product mix, the material in each container should be thoroughly mixed prior to use.1Clear only.2Gray only.3UL746C Approved.LISTINGS AND SPECIFICATIONSDow Corning Corporation Midland, Michigan 48686-0994Dow Corning and Sylgard are registered trademarks of Dow Corning Corporation.Teflon is a registered trademark of E.I. du Pont de Nemours Co.©2000 Dow Corning Corporation.

If de-airing is required to reduce voids in the cured elastomer, consider a vacuum de-air schedule of >28 inches Hg for 10 minutes or until bubbling subsides.REVERSIONWhen two-part condensation curing materials with organo-tin catalysts, such as Q3-6093 adhesive, are cured in confinement (especially in deep section) and are later subjected to high heat conditions, can potentially revert back from a cured elastomer to a flowable polymer.Although this condition is unusual, parts using Q3-6093adhesive should be thoroughly tested in accelerated temperature conditions for this potential limitation.SOLVENT EXPOSUREWhen liquid or vapor solvent or fuel exposure can occur in an application, the silicone adhesives discussed in thisbrochure are intended only to survive splash or intermittent exposures. They are not suited for continuous solvent or fuel exposure. Testing should be done to confirm performance of the adhesives under these conditions.STORAGE AND SHELF LIFEShelf life is indicated by the “Use Before” date found on the product label.For best results, Dow Corning RTV adhesives should be stored at or below 25°C (77°F). Special precautions must be taken to prevent moisture from contacting these materials.Containers should be kept tightly closed and head or air space minimized. Partially filled containers should be purged with dry air or other gases, such as nitrogen.Dow Corning heat-cure adhesives should also be stored at or below 25°C (77°C). Containers should be kept tightly closed and kept in cold storage at all times to extend shelf life.LIMITATIONSThese products are neither tested nor represented as suitable for medical or pharmaceutical uses.PACKAGINGIn general, Dow Corning adhesives/sealants are supplied in nominal 0.45-, 3.6-, 18- and 200-kg (1-, 8-, 40- and 440-lb)containers,net weight.

Information about Dow Corning ® BrandSilicone EncapsulantsSilicones and ElectronicsLong-term, reliable protection of sensitive circuits and compo -nents is becoming more important in many of today’s delicate and demanding electronic applications. Silicone encapsulants provide unparalleled protection for electronic modules and devices ranging from relatively simple to highly complex archi -tectures and geometries. Silicones function as durable dielectric insulation, as barriers against environmental contaminants, and as stress-relieving shock and vibration absorbers over a wide temperature and humidity range.In addition to sustaining their physical and electrical properties over a broad range of operating conditions, silicones are resistant to ozone and ultraviolet degradation and have good chemical stability. The Dow Corning encapsulant family offers many choices to customize or tune product usage and performance for your specific application.DESCRIPTIONDow Corning ® silicone encapsulants or pottants are supplied as two-part liquid component kits comprised of:Mix RatioComponents (by weight or volume)(as supplied) 1:1 Part A/Part B10:1Base/Curing agentWhen liquid components are thoroughly mixed, the mixture cures to a flexible elastomer, which is suited for the protec-tion of electrical/electronic applications. Dow Corning silicone encapsulants cure without exotherm at a constant rate regardless of sectional thickness or degree of confine-ment. Dow Corning silicone elastomers require no post cure and can be placed in service immediately following the completion of the cure schedule with an operating temper-ature range of -45 to 200°C (-49 to 392°F). Several products enable easy rework and repair. Select materials have been classified by Underwriters Laboratories and/or meet military specifications. Standard silicone encapsulants require a sur -face treatment with a primer in addition to good cleaning for adhesion while primerless silicone encapsulants require only good cleaning.PRODUCT INFORMATION1These data were collected on 50-100 gram samples of a lot believed to be typical and should be used as initial estimates of cure times. Times will vary slightly from batch to batch and can be longer or shorter due to thermal mass of your parts and your heating ramp rate. Pretesting is recommended to confirm adequate cure for your application.For primerless adhesion products, cure time is based on time to reach durometer. Full adhesion may take more time at the cure temperature.341These data were collected on 50-100 gram samples of a lot believed to be typical and should be used as initial estimates of cure times.

The 1:1 mix ratio, by weight or volume, simplifies the proportioning process. To ensure uniform distribution of filler, Parts A and B must each be thoroughly mixed prior to their combination in a 1:1 ratio. When thoroughly blended, the Part A and B liquid mixture should have a uniform appearance. The presence of light-colored streaks or marbling indicates inadequate mix-ing and will result in incomplete cure.Due to the fast-curing characteristics of some encapsulants included in this data sheet, automated mix and dispense equipment should be utilized. In applications sensitive to air entrapment, deairing with 28 to 30 inches Hg vacuum is required.MixinG – 10:1/BaSe:CurinG aGenTDow Corning silicone 10:1 encapsulants are supplied in two parts as lot-matched base and curing agent that are mixed in a ratio of 10 parts base to one part curing agent, by weight. After thoroughly mixing base and curing agent, agitate gently to reduce the amount of air introduced. Allowing the mixture to set for 30 minutes before pouring may be adequate for removal of the air introduced during mixing. If air bubbles are still present, vacuum deairing may be required. Deair in a container with at least four times the liquid volume to allow for expansion of material. Air entrapped in the mixture can be removed by using a vacuum of 28 to 30 inches Hg. Continue the vacuum until the liquid expands and settles to its original volume and bubbling subsides. This may take 15 minutes to 2 hours depending on the amount of air introduced during stirring. For best curing results, glassware and glass or metal stirring implements should be used. Mix with a smooth action that does not introduce excess air.PoT Life/WorkinG TiMeCure reaction begins with the mixing process. Initially, cure is evidenced by a gradual increase in viscosity, followedby gelation and conversion to a solid elastomer. Pot life is defined as the time required for viscosity to double after Parts A and B (base and curing agent) are mixed. Please refer to individual pot life for each silicone encapsulant.PRIMER SELECTION GUIDESpecification Writers: Please contact your local Dow Corning sales office or your Global Dow Corning Connection before writing specifications on these products.Product Special Properties Substrates Compatible SiliconesDow Corning®P5 00 Adhesion Promoter – Clear The most versatile of all Dow Corning primers for thewidest range of silicones and electronics applications.This clear primer is similar to Dow Corning® 1 00 OSPrimer but uses a slightly different adhesion promotercombination.

Care should be taken to minimize air entrap-ment. When practical, pouring/dispensing should be done under vacuum, particularly if the component being potted or encapsulated has many small voids. If this technique can-not be used, the unit should be evacuated after the silicone encapsulant has been poured/dispensed.Dow Corning silicone encapsulants may be either room tem-perature (25°C/77°F) or heat cured. Room temperature cure encapsulants may also be heat accelerated for faster cure. Ideal cure conditions for each product are given in the prod-uct selection table. Two-part condensation cure encapsulants should not be heat accelerated above 60°C (140°F).Dow Corning® 255 Curing Agent should be stirred prior to use because some settling may occur during shipping and storage. The curing agent is reactive with atmospheric mois-ture so care should be exercised to limit exposure to air prior to use.PreParinG SurfaCeSIn applications requiring adhesion, priming will be required for the silicone encapsulants. See the Primer Selection Guide for the correct primer to use with a given product. For best results, the primer should be applied in a very thin, uniform coating and then wiped off after application. After application, it should be thoroughly air dried prior to application of the silicone elastomer. Additional instructions for primer usage can be found in the Dow Corning litera-ture, “How To Use Dow Corning Primers and Adhesion Promoters” (Form No. 10-366) and in the information sheets specific to the individual primers.uSefuL TeMPeraTure ranGeSFor most uses, silicone elastomers should be operational over a temperature range of -45 to 200°C (-49 to 392°F) for long periods of time. However, at both the low and high temperature ends of the spectrum, behavior of the materials and performance in particular applications can become more complex and require additional considerations.For low-temperature performance, thermal cycling to conditions such as -55°C (-67°F) may be possible, but per-formance should be verified for your parts or assemblies. Factors that may influence performance are configuration and stress sensitivity of components, cooling rates and hold times, and prior temperature history. There are specialized products including Dow Corning® 3-6121 Low Temperature Elastomer that can perform at -65°C (-85°F) and below.At the high-temperature end, the durability of the cured silicone elastomer is time and temperature dependent. As expected, the higher the temperature, the shorter the time the material will remain usable.CoMPaTiBiLiTYCertain materials, chemicals, curing agents and plasticizers can inhibit the cure of Dow Corning silicone encapsulants. Most notable of these include:• Organotin and other organometallic compounds• Silicone rubber containing organotin catalyst• Sulfur, polysulfides, polysulfones or other sulfur-containing materials• Amines, urethanes or amine-containing materials• Unsaturated hydrocarbon plasticizers• Some solder flux residuesIf a substrate or material is questionable with respect to potentially causing inhibition of cure, it is recommended that a small scale compatibility test be run to ascertain suitability in a given application. The presence of liquid or uncured product at the interface between the questionable substrate and the cured gel indicates incompatibility and inhibition of cure.Dow Corning 255 Elastomer is not subject to these inhibi-tion concerns but may experience reversion in sealed appli-cations at high temperature and pressure. rePairaBiLiTYIn the manufacture of electrical/electronic devices it is often desirable to salvage or reclaim damaged or defective units. With most non-silicone rigid potting/encapsulating materials, removal or entry is difficult or impossible without causing excessive damage to internal circuitry. Dow Corning silicone encapsulants can be selectively removed with relative ease, any repairs or changes accomplished, and the repaired area repotted in place with additional product.To remove silicone elastomers, simply cut with a sharp blade or knife and tear and remove unwanted material from the area to be repaired. Sections of the adhered elastomer are best removed from substrates and circuitry by mechani-cal action such as scraping or rubbing and can be assisted by applying Dow Corning®brand OS Fluids.Before applying additional encapsulant to a repaired device, roughen the exposed surfaces of the cured encapsulant with an abrasive paper and rinse with a suitable solvent. This will enhance adhesion and permit the repaired material to become an integral matrix with the existing encapsulant. Silicone prime coats are not recommended for adhering products to themselves.HandLinG PreCauTionSDow Corning 255 Elastomer curing agent and uncured catalyzed material will burn skin and eyes upon prolonged contact. In case of eye contact, flush with copious amounts of water for at least 15 minutes and seek medical attention at once. Skin contact areas should be washed with soap and water. Persistent irritation should receive medical attention.9Dow Corning and Sylgard are registered trademarks of Dow Corning Corporation.©2000-2008 Dow Corning Corporation.
