High lights! Radiation curing with Laromer?, Lucirin? and Larolux?

Constancy of innovations

For more than 30 years, BASF has constantly been setting standards in resource-saving, emission-free radiation curing products with its high-performance resins and photoinitiators. Fast drying, no VOC emission and energy efficiencies were and are the factors behind BASF`s success in this area. The goal to help our customers being more successful motivated us to develop not only resins, monomers and initiators but also curing technology like the Larolux? process to cure three-dimensional substrates.

For the customer means with the customers

Practical innovations and solutions are only possible if the practical world is brought into the laboratory. In BASF`s UV research centers, our scientists work out the standards for tomorrow`s radiation-curable products together with equipment manufacturers and customers. Quality needs a foundation

BASF`s integrated system, known as “Verbund”, means a coordinated supply of raw materials from within the company itself and thus the highest level of delivery reliability and consistent product quality. In other words, regardless of when and where you need us, you can always count on BASF to the same extent.

What do you expect?

Simply expect more. The spectrum and possibilities for radiation curing are still far from being exploited to the fullest. We are put-ting all our efforts into continuing to offer you all the innovations and associated opportunities in a sure and reliable way. Our aim is to continue doing that as the leader in innovation.

How to set standards day by day …

Preserve the performance of your substrates Today and in the future, scratch resistance is an essential requirement for UV coating on parquet, furniture, plastic substrates and the next-generation automotive coatings. The new BASF product Laromer ? PO 9026, based on nano-technology, is designed to formulate radiation-curable coatings with outstanding scratch resistance.

To combine the excellent scratch resistance with weather durability for any outdoor application, we have developed highly functional, aliphatic urethane acrylates. Depending on the way of applying the coating, you might choose Laromer ? UA 9050 as a solvent-based version for spray application or Laromer ? UA 9048 as a 100 % product diluted with Laromer ? DPGDA.

Ambitious UV applications need specialized products One example is the success story of our photoinitiator Lucirin ? TPO, developed 25 years ago. With this initiator it became possible, for the first time, to cure pigmented varnishes without any yellowing. Since that time we have expanded the Lucirin ? TPO family to offer always an initiator that matches your requirements. The latest development is our Lucirin ? TPO-XL, a liquid phosphine oxide with improved efficiency and still remarkable low in yellowing.Principle features of BASF′s Lucirin ?

Ecology and efficiency combined

How eco-friendly is a product? How eco-friendly is its application? How eco-friendly is the final product? And how eco-friendly is the product by comparison with other products? These are questions that previously could never be answered accurately. That is why BASF developed the eco-efficiency analysis, where ecological factors and efficiency are combined so that different products and processes can be compared as a defined case study.

The Eco-efficiency analysis:

? a strategic tool developed by BASF to measure eco-efficiency ? p rovide a quantitative measure of the economic and ecological benefits of a product or process as compared to other products or processes

? i dentification of the most sustainable product or process for a defined customer benefit

? e ach single study is based on solid facts with respect to the defined application only

The dual innovation Laromer ? LR 9000

Laromer ? LR 9000 for ambitious formulations

Dual-cure resins are products, which combine two different cross-linking mechanisms within a single molecule. These innovative products allow the user to overcome various limitations, which are present in todays′s mono-curing systems.

Laromer ? LR 9000 combines the advantage of rapid, UV-light-initiated polymerization of acrylic ester groups with the UV-light-independent polyaddition of the isocyanate groups. Laromer ? LR 9000 can be used as a single resin or in combination with a polyol in a two-component system. When it is used together with an OH- resp. polyol component, you might use the following formula to compute the theoretical equivalent quantity of Laromer ? LR 9000 required for crosslinking 100 g of any OH/polyol component.

Lucirin ? photoinitiators

The Lucirin ? family stands for photoinitiators used in UV-curable coatings and inks. This photoinitiators are preferredly used to cure thick films, pigmented and/or UV-stabilized coatings and inks. Based on this property profile, even sophisticated applications can be realized. BASF offers these low-odor, acylphosphine oxide photoinitiators in powder and liquid forms.

Lucirin ? BAPO – Particularly suitable for pigmented UV coatings and printing inks. It allows very thick films to be cured. Since its solubility is limited, it should be incorporated well.

Lucirin ? TPO – It is used in pigmented and clear coatings to produce low-odor films. Of particular importance is the low yellowing - especially required for white-pigmented coatings and inks.

Lucirin ? TPO-L – Being a liquid, it is very easy to incorporate into coatings formulations. The low yellowing makes it a good choice for light-colored coatings.

Lucirin ? TPO-XL – Combines the advantages of the Lucirin ? types described above. Especially easy incorporation into recipes because of its liquid form of supply; little yellowing and high effectiveness make it the first choice.

or in short: simpler, faster and better!

UV curing has already revolutionized coating technology, but anything good can be improved further – and even simplified, thus opening up new applications. A principle that applies to radiation technology for 3D applications or for small-scale runs. The technology of UV curing in carbon dioxide* recently developed by us uses a very simple method to eliminate technical difficulties that are otherwise caused by atmospheric oxygen. Atmospheric oxygen interferes with the curing reaction of UV coatings.Carbon dioxide is heavier than air and can easily be f illed into a tank to form an inert gas blanket. Losses due to escaping gas can thus be reduced. When the oxygen content is low the UV dose can be decreased to such an extent that simpler and cheaper UV lamps can be used. 3D objects can be illuminated by simple reflectors. All these factors save time and money, enhance quality, increase flexibility and additionally save the environment.

1 Aluminum reflectors:

Lining the tank with aluminum

(e.g., with aluminum foil) is

sufficient and permits perfect

illumination of 3D substrates

without special reflectors.

2 UV lamps:

As the UV dose can be reduced

substantially it is now possible

to use low-cost UV lamps. The

distance between lamp and

substrate is of minor importance.

3 Space:

for introducing carbon dioxide;

both gas or dry ice are possible 4 Carbon dioxide:

Carbon dioxide is heavier than

air and can easily be filled into

a tank to form an inert gas

blanket. The gas requirement is low and oxygen is therefore no

longer a problem.

5 Permeable aluminum base:

The carbon dioxide is slowly

introduced through this and

distributed. Strong gas eddies

are thus avoided.

Here, too, aluminum ensures

perfect UV yield.

6 Objects:

3D or 2D objects are fully

illuminated. The UV coating

is fully cured.
