HCID 21863578Urethane acrylate

Procedure

260.0 g of the polyester A1 (OHN 41) were melted and added in portions at 120° C. with vigorous stirring to a mixture of 83.3 g of a 1:1 adduct of IPDI and hydroxyethyl acrylate, 0.7 g of IONOL CP and 0.2 g of DBTL. After about one hour of stirring, the NCO content was below 0.1% and the hot reaction mixture was poured from the flask onto a sheet. As soon as the reaction mass had solidified and cooled, it was mechanically size-reduced and ground. The Tg of this product was 45° C.
