Sometimes less is more

Do you need to obtain lower viscosity without sacrificing performance? Try GENOMER* 4212. Typical urethane acrylates deliver high performance at the cost of high viscosity. GENOMER* 4212 is an exception. At just 14,000 mPas, GENOMER* 4212 still delivers outstanding chemical and abrasion resistance, toughness, weatherability and more. It also offers excellent adhesion on a wide range of substrates.

The formulation below compares the performance of GENOMER* 4212 to GENOMER* 4267 in an experimental coating for steel tool parts.
