Document Type and Number:
Japanese Patent JP6803343
Kind Code:
B2
Abstract:
The present invention relates to isocyanate-free polyurethane composition for adhesives, sealants and coating materials. In particular, the present invention relates to isocyanate-free polyurethane composition including polymers (A) carrying cyclic carbonate groups, which do not comprise or are not based on isocyanates, obtained by reaction of polymers which carry carboxyl groups, selected from the group encompassing polyesters based on diols or polyols and on dicarboxylic or polycarboxylic acids and/or derivatives thereof, or poly(meth)acrylates, with five-membered cyclic carbonates that are functionalized with hydroxyl groups, and a curing agent (B) having at least one amino group and at least one further functional group, wherein the further functional group is not an isocyanate group.
