摘要:
A primer of aqueous emulsion type for powder coating, which does not cause environmental pollution, has an excellent safety and is excellent in the adhesion between a metallic body and a synthetic resin coating; and a process for producing a metallic body coated with a synthetic resin by using the primer. The primer comprises an acid-modified diene polymer, an organic amine or ammonia, and water. A metallic body coated with a synthetic resin is produced by applying the primer to the surface of a metallic body, followed by curing and baking, and coating the resultant body with a synthetic resin by fluidized bed coating or electrostatic coating.

The composite polymer of the invention is obtained by reacting (a) an elastomer having a carboxyl group with (b) metal oxide fine particles each having an epoxy ring-containing group on the particle surface. A thermally cured product of the composite polymer of the invention is a material favorable for forming a primer layer which has not only high transparency but also excellent adhesion to a hard coat layer and is excellent also in scratch resistance, heat resistance, weathering resistance, dyeing property, impact resistance and the like. An article such as an optical article whose primer layer comprises the thermally cured product of the composite polymer has high transparency and is excellent also in heat resistance.

Elastomer coating composition are disclosed which cure at room temperature, and form highly flex-resistant, durable, and flexible protective layer on elastomers and provides excellent adhesion to elastomeric and metal substrates. The coating is a solvent solution of (A) a carboxylated hydrogenated acrylonitrile-butadiene copolymer, and (B) a room temperature isocyanate curing component. Coated bonded elastomer-metal composites are obtained without an additional application of heat to cure the coating.
摘要:
An emulsion type primer for powder coating, which is pollution-free and excellent in safety, achieves a good adhesion between a metallic material and a synthetic resin coating and contains water as a medium, and a process for producing a metallic material coated with a synthetic resin by using this primer. This primer comprises an acid-modified diene polymer, an organic amine or ammonia and water. A metallic material coated with a synthetic resin is produced by applying the primer composition onto the metallic surface, curing the same by baking and then coating it with the synthetic resin by the fluidized bed dip coating method or the electrostatic coating method.

A rubber-coated gasket material has a rubber layer formed on one or both sides of a metal sheet. The rubber layer has incorporated therein a nitrile rubber containing a carboxyl group in such an amount that the proportion of a carboxylic monomer as calculated in term as of a monomer content in the rubber component is in the range of 2-15 wt%. The rubber layer is formed in a thickness of 10 - 300 µm per side, and bonded to a metal sheet with a primer layer based on a phenolic resin being interposed between the rubber layer and the metal sheet.
