DESCRIPTION

Dow Corning? brand silicone LED (light emitting diode) encapsulants are designed to meet the challenging needs of the LED market, including high adhesion, high purity, moisture resistance, thermal stability and optical transmittance. Silicone materials can absorb stresses caused by thermal cycling inside the package, protecting the chip and the bonding wires. With the electronics industry quickly moving toward lead-free processing, silicone encapsulants, with their demonstrated, excellent stability at reflow temperatures, are a natural fit for LED applications. APPLICATION METHODS Compatible with commercially available equipment and

industry standard processes PROCESSING/CURING These products are also compatible with commercially available equipment and industry standard processes. These materials can be dispensed or molded depending on the product and application.

Dow Corning? brand OS Fluids are recommended to clean cured or uncured silicone residue from application equipment. ADHESION

Dow Corning LED materials are specially designed for adhesion to commonly used LED substrates. Surface treatments such as chemical etching or plasma treatment may provide a reactive surface and improve adhesion to these types of substrates. In general, increasing the cure temperature and/or cure time will improve the ultimate adhesion. USEFUL TEMPERATURE RANGES

For most uses, silicone encapsulants and resins 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 performance

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-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 useable.

COMPATIBILITY

Certain 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,

unsaturated hydrocarbon plasitcizers,

and some solder flux residues. If 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.

USABLE LIFE AND

STORAGE

Shelf life is indicated by the “Use

Before” date found on the product

label. Dow Corning two-part

products should be stored at or

below 25 °C (77 °F). Containers

should be kept tightly closed at all

times to extend shelf life. Check the

硅烷偶联剂kh

硅烷偶联剂kh570 一、概述: 偶联剂kh570是一类具有两不同性质官能团的物质,它们分子中的一部分官能团可与有机分子反应,另一部分官能团可与无机物表面的吸附水反应,形成牢固的粘合。偶联剂在复合材料中的作用在于它既能与增强材料表面的某些基团反应,又能与基体树脂反应,在增强材料与树脂基体之间形成一个界面层,界面层能传递应力,从而增强了增强材料与树脂之间粘合强度,提高了复合材料的性能,同时还可以防止不与其它介质向界面渗透,改善了界面状态,有利于制品的耐老化、耐应力及电绝缘性能。 化学名称:γ―甲基丙烯酰氧基丙基三甲氧基硅烷 化学结构式:CH3CCH2COO(CH2)3Si(OCH3)3 对应牌号:中科院KH-570、美国联碳公司A-174、美国道康宁公司Z-603、日本信越公司KBM-503 典型特征:偶联剂570为甲基丙烯酰氧基官能团硅烷,外观为无色或微黄透明液体,溶于丙酮、苯、乙醚、四氯化碳,与水反应。沸点为255℃,密度P25'g/m1:1.040,折光率ND:1.429,闪点:88℃,含量为≥97% 二、应用领域: 1、用于玻璃纤维的表面处理,能改善玻璃纤维和树脂的粘合性能,大大提高玻璃纤维增强复合材料的强度、电气、抗水、抗气候等性能,即使在湿态时,它对复合材料机械性能的提高,效果也十分显着。目前,

在玻璃纤维中使用硅烷偶联剂已相当普遍,用于这一方面的硅烷偶联剂约占其消耗总量的50%,其中用得较多的品种是乙烯基硅烷、氨基硅烷、甲基丙烯酰氧基硅烷等。 2、用于无机填料填充塑料。可预先对填料进行表面处理,也可直接加入树脂中。能改善填料在树脂中的分散性及粘合力,改善工艺性能和提高填充塑料(包括橡胶)的机械、电学和耐气候等性能。 3、用作密封剂、粘接剂和涂料的增粘剂,能提高它们的粘接强度、耐水、耐气候等性能。硅烷偶联剂往往可以解决某些材料长期以来无法粘接的难题。硅烷偶联剂作为增粘剂的作用原理在于它本身有两种基团;一种基团可以和被粘的骨架材料结合;而另一种基团则可以与高分子材料或粘接剂结合,从而在粘接界面形成强力较高的化学键,大大改善了粘接强度。硅烷偶联剂的应用一般有三种方法:一是作为骨架材料的表面处理剂;二是加入到粘接剂中,三是直接加入到高分子材料中。从充分发挥其效能和降低成本的角度出发,前两种方法较好。 三、使用方法 1、表面预处理法:将硅烷偶联剂配成0.5~1%浓度的稀溶液,使用时只需在清洁的被粘表面涂上薄薄的一层,干燥后即可上胶。所用溶剂多为水、醇、或水醇混合物,并以不含氟离子的水及价廉无毒的乙醇、异丙醇为宜。除氨烃基硅烷外,由其它硅烷偶联剂配制的溶液均需加入醋酸作水解催化剂,并将pH值调至3.5~5.5。长链烷基及苯基硅烷由于稳定性较差,不宜配成水溶液使用。氯硅烷及乙氧基硅烷水解过程中伴随有严重的缩合反应,也不宜配成水溶液或水醇溶液使用,而多配成醇

Q: What is the recommended culture medium working volume in a Corning 5L Erlenmeyer flask?A: We recommend a working volume range of 2.5 to 3.0L of culture medium with Corning 5L Erlenmeyer flasks. Specifically for the baffled option, we recommend a working volume no less than 2.5L, the minimal volume for which the baffles were designed and optimized. Due to the height of the baffles, working volumes less than 2.5L could experience forces that take away the benefits of the baffles. Q: What is the recommended agitation rate for Corning 5L Erlenmeyer flasks? A: The optimal agitation rate will depend on the diameter of the orbit of the individual shaking platform, the cell type being cultured, the medium used and whether a baffled or plain bottom Erlenmeyer flask is used. With 25 mm orbit shakers, we recommend a rate of 90 rpm for CHO and Sf9 cells when cultured in Corning 5L Erlenmeyer flasks. It is important to empirically determine the agitation rate depending on conditions. This could be done by observing the amount of culture medium foaming with different agitation rates (90 to 120 rpm). The agitation rate with no or minimum foaming should be used as a good start-ing point. Typically we find the ideal rpm will need to be decreased as the size of the Erlenmeyer flask increases. Q: What is the recommended seeding density for 5L Erlenmeyer flasks? A: We recommend using the seeding density optimized for your given cell type or clone. Seeding den-sities of 0.3 to 0.5 x 106 cells/mL are typical for CHO cell culture and 0.5 x 106 to 1 x 106 cells/mL for Sf9 cell culture. Q: What is the recommended culture medium-feeding protocol in Corning 5L Erlenmeyer flasks?A: We recommend using the culture medium and feeding protocol (fed batch) optimized for your given cell type as a starting point. Some fine tuning of the feeding protocol may be needed for the maximum performance in 5L Erlenmeyer flasks. Q: What is the recommended scale up protocol for CHO cells in Corning 5L Erlenmeyer flasks?A: If starting from cryopreserved CHO cells, we recommend thawing cells into a Corning 125 mL Erlenmeyer flask using your standard protocol. Culture cells for several passages until cells are fully recovered and reach >2 x 106 cells/mL density by day 3 or 4. Always use cells from the mid logarithmic growth phase for the scale up. From 125 mL flask (40 mL working volume), scale up cells to 1L Corning Erlenmeyer flask (300 mL working volume), then to 5L Erlemeyer flask (2.5 to 3.0L working volume). It could take about 6 to 8 days to scale up from 125 mL to 5L Erlenmeyer flask depending on the cell growth rate. Q: Why might I want to use the baffled Corning 5L Erlnemeyer flask over a standard 5L Erlenmeyer flask?A: Usually we find that the baffles provide better aeration for cells, especially at a lower rpm. You may find that by using a baffled Erlenmeyer flask you can decrease the rpm from what you typically use.Q: Why is there an angled feature around the neck of the vessel? A: The angled feature located at the neck of the vessel will reduce foam when filling and pouring out of the vessel. Corning ? 5L Erlenmeyer Flask Frequently Asked Questions
