CARBOXYL-FUNCTIONAL POLYESTER EPOXY RESIN POWDER COATINGS BASED ON 1,3-PROPANEDIOL
摘要
A polyester powder coating composition formed by reacting: a) a polyester resin formed by reacting one or more aliphatic glycols and one or more polycarboxylic acids and/or anhydrides, wherein the aliphatic glycol is comprised of 5 to 90% 1,3-propanediol on a molar basis, in the presence of an esterification catalyst and then endcapping the polyester with an endcapping agent to ensure that the polyester has carboxyl chain ends; and b) an epoxy resin crosslinking agent.
