CROSSLINKABLE COMPOSITION CROSSLINKABLE WITH A LATENT BASE CATALYST |
摘要 |
The present invention relates to a crosslinkable composition comprising at least one crosslinkable component and a latent base crosslinking catalyst, which crosslinkable composition has a solids content of at least 55 wt% (dry weight after crosslinking relative to the total weight of the crosslinking composition) wherein the latent base catalyst is a substituted carbonate salt according to formula 1
wherein X + represents a cation, preferably a quaternary ammonium or phosphonium, and wherein R is hydrogen, alkyl, aryl or aralkyl group. The invention relates in particular to a composition crosslinkable by Real Michael Addition (RMA) reaction wherein a component with at least 2 activated unsaturated groups and a component with at least 2 acidic protons C-H in activated methylene or methine groups react and crosslink to each other in the presence of a strong base catalyst. The invention further relates to a coating composition comprising the crosslinkable composition according to the invention, a novel catalyst composition and to the use of said catalyst composition according to the invention as a latent base crosslinking catalyst in coating compositions, preferably in RMA crosslinkable compositions. |
