  • Powder coating composition comprising unsaturated polyesters and uses thereof
    Patent number: 6194525
    Abstract: The powder coating composition of the present invention includes a low-temperature mixture of a powder (A) and a powder (B), in which at least the powder (A) includes an unsaturated polyester resin and a free radical initiator for initiating polymerization of unsaturated polyester resins in the powder coating composition and the powder (B) includes a polymerization promoter and methods for making the composition. The powder (B) may further include an unsaturated polyester. The powders (A) and (B) are physically mixed at temperatures below which the polymerization promoter would cause the free radical initiator to initiate polymerization of the powder coating composition. Subsequently, the physically mixed powder coating composition is applied to a substrate and cured, during which the polymerization promoter causes the free radical initiator to initiate the curing reaction.
