Universal, emission-free and economical

Bayer MaterialScience AG : 15 March, 2005  (Company News)
Coatings that cure quickly under energy-saving UV light have a number of economic advantages. The coated articles can, for example, be immediately stacked and made ready for transport as soon as they leave the production line.
The environment also benefits if the radiation-curing coatings do not emit any volatile organic compounds (VOC). With Roskydal® UA XP 2587, Bayer MaterialScience AG has now come up with a low-viscosity aliphatic urethane acrylate that can be used to formulate high-quality emission-free coatings.

The new product can be combined with acrylate oligomers and reactive thinners to produce coatings with 100-percent solids. On the other hand, it can also be easily emulsified in water and thus offers an excellent basis for solvent- and amine-free UV-curing waterborne coatings.

“This makes Roskydal® UA XP 2587 ideal for many different formulations. It is also suitable for all methods of application - a true all-round resin,” says Dr. Wolfgang Fischer, an expert in radiation-curing coatings at Bayer MaterialScience. Normally, many different raw materials are needed to formulate UV-curing coatings for the various methods of application - roller coating, curtain coating and spraying.

The cured finishes are brilliant, scratchproof and resistant to water, solvents and household chemicals. They also have excellent lightfastness. The experts at Bayer MaterialScience have shown that wood and furniture finishes and coatings for parquet, laminate and PVC flooring based on Roskydal® UA XP 2587 have outstanding properties. The finish can range from high-gloss to matte and be either clear or pigmented. The new resin is also ideal for general plastics coating applications and for printing inks.
