Abstract:
In a first coating step, low electrical conductivity is imparted to a coating surface 21 of a non-electrically conductive coating object 20 and a first paint film is formed by applying a charged first paint to the coating surface 21 with free ions being suppressed. In a second coating step, a second paint film is formed by applying a negatively-charged second paint to a surface of the first paint film with free ions being suppressed, before the first paint film dries.

Abstract:
A conductive primer coating composition comprising a resinous film forming binder, a fibrous, carbonaceous material and a light colored pigment. This coating composition may be applied to plastic or other substrates having low electrical conductivity to form a light colored, conductive coating. The application of this first coating and subsequent coatings by the electrostatic method of application is facilitated.

A coated molded article having good adhesion to a coating film and resistance to gasohol as well as excellent appearance can be obtained by applying a primer coating to the surface of a molded article or irradiating the surface with plasma without applying any washing-treatment with a halogen atom-containing organic solvent and then applying a top coat onto the article, if the molded article is formed from a resin composition comprising (A)a polypropylene; (B)a specific ethylene-propylene-diene terpolymer rubber; (C) a specific ethylene-propylene copolymer rubber; and (D) a specific polyhydroxypolyolefin, the amounts of these components (A) to (D) satisfying the following relations:10.ltoreq.[(B)+(C)]/[(A)+(B)+(C)].ltoreq.60 (% by weight)1.ltoreq.(C)/[(B)+(C)].ltoreq.50 (% by weight)0.5.ltoreq.(D)/[(A)+(B)+(C)+(D)].ltoreq.10 (% by weight)
Abstract:
There is provided a method for coating a metal substrate by the use of a polyvinylidene fluoride resin composition. The method comprises forming a coating film made of a melted resin composition on the surface of an undercoated metal substrate at a temperature of from 200.degree. to 350.degree. C., said resin composition containing a major amount of polyvinylidene fluoride and from 5 to 40% by weight of an inorganic filler based on the total weight of the resin composition; and precooling said coating film to a temperature T.sub.A and then keeping said coating film at the temperature T.sub.A for at least one minute, wherein said temperature T.sub.A (.degree.C.) satisfies the inequality:T.sub.C -10.degree.C..ltoreq.T.sub.A .ltoreq.T.sub.C +10.degree.C.,said T.sub.C (.degree.C.) being the crystallization temperature for the polyvinylidene fluoride.
Abstract:
a method and product relating to a powdered coated resinous article. The surface of the resinous article is sealed to resist the effects of gases released from the article during heating. The sealing layer may contain a lead silicate chromate additive. A conductive exterior surface is then formed on the article and subsequently a powder paint is applied to the article under the influence of an electrostatic field. The coating is then heated sufficiently to merge the particles into a continuous film. The powder coating may be acrylic, polyester or epoxy. The sealing and forming a conductive layer may be done in one operation.
Abstract:
The present invention relates to a substrate having (a) a first material applied to at least a portion of the substrate, and (b) a coating layer deposited from a powder coating composition including a film-forming resin, and optionally a crosslinker that is reactive with the film-forming resin, in direct contact with at least a portion of the substrate to which the first material has been applied. The first material is (i) a catalyst that catalyzes cure of the powder coating composition, (ii) a component reactive with the film-forming resin and/or the crosslinker of the powder coating composition, and/or (iii) a rheology modifier.
