ABSTRACT:
Addition polymers containing a plurality of terminal and/or pendant amine groups in which the nitrogen atom of at least some of such groups is of primary or secondary character, or aldimine or ketimine groups form the main film-forming component in compositions for coating and the like purposes, which also contain a polyfunctional acrylic monomer, such as ethylene glycol diacrylate, with or without monoethylenically unsaturated acrylic ester. Such compositions provide durable films having excellent mechanical and resistance properties even on ambient curing though baking may be used to accelerate the cure. A method of use is also claimed in which the components are mixed in suitable vehicles, e.g. dispersant or solvent media, optionally with fillers and/or pigments, as desired, and after application of the composition, such as for coating, it is cured by exposure to ambient conditions, naturally occurring or controlled, or it is cured at elevated temperatures or by applying a plurality of curing conditions in succession, e.g. first to ambient conditions and subsequently to elevated temperatures in one or more stages of baking.
