Abstract

An improved method of pretreating and electrostatically coating an article made of a material which has little or no conductivity, and the article made therefrom.

Claims (15)

1. A conductivity inducing surface treatment composition applied to a substrate having poor electrical conductivity comprising at least one member selected from the group consisting of halophors of nonionic surfactants; halophors of amphoteric surfactants; iodophors, chlorophors and bromophors of anionic surfactants; halophors of glycol ether or polyvinylpyrrolidone; hypohalites; hypohalates; perhalates; iodine, chlorine, bromine, fluorine; and mixtures thereof.

2. A conductivity inducing surface treatment composition applied to a substrate having poor electrical conductivity wherein said surface treatment composition comprises a halogen complex which is an iodophor of a surface active agent.

3. The conductivity inducing surface treatment composition of claim 2 wherein said surface treatment composition comprises an iodophor of polyethoxylated nonylphenol, an iodophor of polyethoxylated fatty alcohol or a mixture thereof.

4. The article of claim 2 , said article further comprising an electrostatic coating.

5. An article formed of a substantially nonconductive material wherein said article is pretreated with a surface treatment composition comprising at least one member selected from the group consisting of halophors of nonionic surfactants; halophors of amphoteric surfactants; iodophors, chlorophors and bromophors of anionic surfactants; halophors of glycol ether or polyvinylpyrrolidone; hypohalites; hypohalates; perhalates; iodine, chlorine, bromine, fluorine; and mixtures thereof, and electrostatically coated.

6. The article of claim 5 wherein said halogen salt is an alkali metal or alkaline earth metal halide salt, hypohalite, hypohalate, or perhalate.

7. The article of claim 5 wherein said surface treatment composition is a hypohalite.

8. The article of claim 7 wherein said hypohalite is sodium hypochlorite.

9. The article of claim 5 wherein said article is a fishing rod, fishing lure, archery bow, automobile body, automobile accessory, siding, furniture, shelving, door, cookware or appliance.

10. An article pretreated with a surface treatment composition comprising at least one halogen complex which is an iodophor and electrostatically coated.

11. The article of claim 10 wherein said iodophor is an iodophor of polyethoxylated nonylphenol, an iodophor of polyethoxylated fatty alcohol or mixture thereof.

12. A conductivity inducing surface treatment composition applied to a substrate, said conductivity inducing surface treatment comprising at least one halogen, a halogen salt, a halogen complex or mixture thereof wherein said halogen is iodine.

13. An article formed of a substantially nonconductive material wherein said article is pretreated with a surface treatment composition comprising at least one member selected from the group consisting of halophors of nonionic surfactants; halophors of amphoteric surfactants; iodophors, chlorophors and bromopbors of anionic surfactants; halophors of glycol ether or polyvinylpyrrolidone; hypohalites; hypohalates; perhalates; iodine, chlorine, bromine, fluorine; and mixtures thereof.

14. A conductivity inducing surface treatment composition applied to a substrate having poor electrical conductivity comprising at least one member selected from the group consisting of iodophors nonionic surfactants, iodophors of amphoteric surfactants; iodophors of cationic surfactants; iodophors of anionic surfactants; iodophors of glycol ether, iodophors of polyvinylpyrrolidone, and mixtures thereof.

15. The conductivity inducing surface treatment composition of claim 14 comprising at least one member selected from the group consisting of iodophors of nonionic surfactants; iodophors of glycol ether; iodophors of polyvinylpyrrolidone; and mixtures thereof.
