ABSTRACT:
An aqueous coating composition based on a highly stable emulsion of polymerized monomers curable in the presence of a strong acid catalyst at low temperatures and therefore usable on thermoplastic substrates. The emulsion includes non-functional monomers whose combined glass transition temperature is such as to give desired hardness and flexibility required of highly demanding product applications. Water miscibility and extended period stability of the emulsion is maintained in the presence of the strong acid catalyst by use of disclosed surfactant agents which are alkoxylated and/or etherified as needed to impart these characteristics. A high degree of solvent resistance is achieved by addition of a hydroxyl functionality to the emulsion for reaction with the crosslinking agent in the presence of the acid catalyst. The emulsion suitable for the coating composition is also set forth.
