WATER-THINNABLE COATING COMPOSITIONS FROM AMINOALKYLATED INTERPOLYMERS

摘要

This invention is directed to a water-thinnable coating composition comprising a water-miscible solvent, a water-soluble acidified aminoalkylated vinyl interpolymer and an epoxy resin. The important feature of this invention is that the aminoalkylated vinyl interpolymer is acidified with hydrobromic acid optionally containing up to 30 mole percent hydrochloric acid. The coating compositions of this invention demonstrate excellent cure rates even under cool and/or damp conditions.
