Crosslinkable compositions containing polyepoxides and polyacid curing agents.

摘要

The invention provides a curable, liquid coating composition containing components which volatilize at or release volatiles at curing temperature comprising: (a) a polyepoxide, (b) a polyacid crosslinking agent, and characterised by also containing (c) a monocarboxylic acid containing at least 6 carbon atoms. The invention also provides a process for applying a composite coating of a coloured base coat and a clear top coat characterised in that the clear top coat is formed by applying over the base coat a clear coating composition comprising the above curable composition and also substrates so coated.
