Abstract
Polyamide coating compositions that demonstrate strength and toughness, flame and corrosion resistance and resistance to hydrolysis and thermal degradation at coating thicknesses of less than or equal to 0.25 mm or 0.15 mm are provided. Such coating compositions are extremely useful for coating wires or cables that are housed in automotive electrical harnesses.
Claims9
A thermoplastic coating composition comprising:
- a. a polyamide selected from the group consisting of nylon 610, nylon 612, nylon 11, nylon 12 and blends thereof;
- b. an ionic copolymer of at least one .alpha.-olefin having from 2 to 6 carbon atoms and at least one .alpha.,.beta.-unsaturated organic carboxylic acid having from 3 to 6 carbon atoms which is partially or completely neutralized with zinc ions;
- and
- c. an unsaturated dicarboxylic anhydride compatibilizer;
- wherein said ionic copolymer is present in an amount ranging from about 18 to about 27% by wt. based on the total amount of polyamide present in said composition;
- and
- wherein said unsaturated dicarboxylic anhydride of said unsaturated dicarboxylic anhydride compatibilizer is present in an amount ranging from about 0.2 to about 4.0% by wt. based on the total amount of ionic copolymer present in said composition.

A thermoplastic coating composition comprising:
- a. nylon 11;
- b. zinc neutralized ethylene-methacrylic acid copolymer;
- and
- c. maleic anhydride modified polyethylene;
- wherein said zinc neutralized ethylene-methacrylic acid copolymer is present in an amount ranging from about 18 to about 27% by wt. based on the total amount of nylon 11 present in said composition;
- and
- wherein said maleic anhydride of said maleic anhydride modified polyethylene is present in an amount ranging from about 0.2 to about 4.0% by wt. based on the total amount of zinc neutralized ethylene-methacrylic acid copolymer present in said composition.
