EPOXY RESIN COMPOSITIONS

摘要

Curable epoxy resin compositions for producing abrasion resistant, flexible coatings comprise an epoxide resin having two or more epoxy groups per molecule, a curing agent which is a polyamine containing at least three amino hydrogen atoms per molecule, or a precursor of such an amine, and a urethane containing co-curable component which is of general formula (I), in which the R1 groups are the same or different and are selected from hydrogen and methyl, the R2 groups are the same or different polyvalent residues, R3 is a polyvalent residue which is or includes a polyether or polythiol residue, UL represents a urethane group, the values of m may be the same or different and are integers of at least 1, and n is zero or an integer.
