EPOXY COATING COMPOSITIONS

摘要

The epoxy coating composition of two-liquid type that is crosslinked in R.T. and has a good weatherability, comprises (A) copolymer containing epoxy that is consisted of epoxy resin of bisphenol A type (1) and butadiene nitryl copolymer (2) that both end is substituted carboxyl group having 3000-4000 as Mw. and α,β-unsaturated carboxyl acid of ethylen type; (B) acryl monomer that is consisted of alkyl ester (a) of unsaturated carboxyl acid of ethylen type and glycidil ester (b) of α,β-unsaturated carboxyl acid of ethylene type and alkyl ester of α,β-unsaturated carboxyl acid of ethylene type substituted tri-amine.
