Title (EN) A CURABLE URETHANE ACRYLATE COMPOSITION WITH BIMODAL MOLECULAR WEIGHT DISTRIBUTION
(FR) COMPOSITION D'URÉTHANE-ACRYLATE DURCISSABLE PRÉSENTANT UNE DISTRIBUTION BIMODALE DES POIDS MOLÉCULAIRES
Abstract:
(EN) A curable resin composition comprising: (1) a urethane (meth)acrylate comprising a) urethane (meth)acrylate oligomers with a number average molecular weight in the range of from 400 to 1500; and b) urethane (meth)acrylate oligomers with a number average molecular weight in the range of from 1500 to 10000, present in a weight ratio of from 0.1:1 to 25:1; (2) a reactive diluent; and (3) a free radical-generating catalyst, is disclosed.
(FR) L'invention concerne une composition de résine durcissable comprenant : (1) un uréthane-(méth)acrylate comprenant a) des oligomères d'uréthane-(méth)acrylate présentant un poids moléculaire numérique moyen dans la plage de 400 à 1500; et b) des oligomères d'uréthane-(méth)acrylate présentant un poids moléculaire numérique moyen dans la plage de 1500 à 10.000, présents dans un rapport pondéral de 0,1: 1 à 25:1; (2) un diluant réactif; et (3) un catalyseur produisant des radicaux libres.
