CA 2530132
A curing composition is disclosed which is composed of a (meth)acrylic polymer having at least one crosslinkable functional group and a surface tackiness modifying agent having a melting point of not less than 30~C but not more than 200~C at a pressure of 1 atm. The surface tackiness modifying agent is preferably an aliphatic hydrocarbon compound, an aliphatic carboxylic acid, an aliphatic alcohol, an aliphatic carboxylate, a natural wax, an aliphatic carboxylic amide, an organic polymer, or the like. By using this curing composition, it is possible to reduce surface tackiness in a cured product.
L'invention concerne une composition de durcissement qui comprend un polymère (méth)acrylique ayant au moins un groupe fonctionnel réticulable et un agent de modification d'adhérence de surface dont le point de fusion n'est pas inférieur à 30· C et n'est pas supérieur à 200· C à une pression de 1 atm. L'agent de modification considéré est de préférence un composé d'hydrocarbure aliphatique, un acide carboxylique aliphatique, un alcool aliphatique, un carboxylate aliphatique, une cire naturelle, un amide carboxylique aliphatique, un polymère organique, ou autre. Ladite composition permet de réduire l'adhérence de surface d'un produit durci.
