ABSTRACT:
An elastomer-modified phenolic composition is provided which is an reaction product of a phenolic compound and about 5 to about 35 weight percent, based on the total weight of the elastomer-modified phenolic compound, of a functionalized elastomer. Further, there is provided a composition comprising an epoxy resin and a curing agent for the epoxy resin comprising the elastomer-modified phenolic composition. The use of the elastomer-modified phenolic curing agent permits the preparation of low-viscosity powder coating formulations for impact-resistant coatings.
