PROCESS FOR THE PREPARATION OF PHOTOSTABLE SOLVENT-STABLE POLYURETHANE UREA ELASTOMER COATINGS BY A REACTIVE COATING PROCESS

摘要

The present invention is directed to a process for the production of light-stable, solvent-resistant polyurethane urea elastomer coatings by the reactive coating process wherein NCO prepolymers are reacted with 4,4'-diamino-C1-C4-tetraalkyldicyclohexylalkanes containing up to 4 carbon atoms in the alkyl group with continuous mixing and continuous discharge of the reaction mixture.
