摘要:
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.
摘要:
The present invention provides a screen printable coating composition comprising one or more hydroxy functional materials (I), one or more crosslinkers (II) for curing the hydroxy functional materials, and one or more crystalline reactive diluents (III). The coating composition may also include one or more catalysts (IV), plasticizers (V), rheology modifiers (VI), waxes (VII) and coloring agents (VIII). Various additives and fillers may also be included in the coating composition.
摘要:
Resin is mixed with graphite particles to form a blendable, processable premold coating. When the premold coating is incorporated onto the surface of a premold coated molded plastic product produced by the premold process, said coating is rendered electrostatically conductive.
