TAICROS Crosslinking Additive Gives Chemical Resistance to Coatings

March 12, 2013

Evonik Industries is now bringing on to the market the successful
TAICROS crosslinking booster in yet another promising
application: As an additive in UV-curable clear coatings, TAICROS
ensures chemical resistance and improved mechanical properties.
Market demand is growing for eco-friendly alternatives to
conventional solvent-borne coatings; for this reason, UV-curable
clear coatings are becoming increasingly important. Their weak
point so far has been a less than optimal resistance to chemical
attack; TAICROS, however, shows good results in overcoming
this problem. Moreover, the chemical structure of the additive
improves the mechanical properties, particularly for intercoat
adhesion in multicoat structures.

TAICROS is a reactive diluent that promotes UV irradiation
induced crosslinking. The product has already been used
successfully for more than ten years in various applications in the
plastics and rubber industries, for example in plastic films for
protection of photovoltaic cells.

In collaboration with the Fraunhofer Institute for Manufacturing
Engineering and Automation (IPA), Evonik has now developed
novel formulations allowing improved performance in radiation
curable coatings such as UV-curable clear coatings.

At the symposium running concurrently with the ECS, Dr. Marc
Entenmann of the Fraunhofer IPA will give a presentation at 12.00
noon on March 18 in the NürnbergConvention Center. He will talk
about UV-curable clear coatings and present the results of the
work done jointly with Evonik.
