Plastisols comprising a finely divided vinyl chloride polymer and the usual fillers, additives, and plasticizers, to which plastisols is added, as an adhesion promoter, an adduct formed between an epoxy compound and the condensation product formed between (1) a polyaminoamide, comprising polymerized fatty acids and an excess of a polyalkylene polyamine and (2) a carboxylic acid or an ester thereof, and methods for coating or adhering a substrate with such plastisols by applying said plastisols to the substrate and baking at temperatures of 90.degree. C. and up.

Polyvinyl chloride plastisols

What are disclosed are plastisols comprising a finely divided vinyl chloride polymer and the usual fillers, additives, and plasticizers, to which plastisols is added, as an adhesion promoter, the condensation product formed between (1) a polyaminoamide, comprising polymerized fatty acids and an excess of a polyalkylene polyamine and (2) a carboxylic acid or an ester thereof, and methods for coating or adhering a substrate with such plastisols by applying said plastisols to the substrate and baking at temperatures of 90.degree. C. and up.

What are disclosed are a method for the bonding of metallic materials and for producing coatings on metallic materials with a polyvinyl chloride plastisol which has improved adhesion at baking temperatures of 90.degree. C. and up and which contains, as an adhesion-improving additive, a condensation product of a polymerized fatty acid, a polycarboxylic acid having three or more COOH groups, an optional dicarboxylic acid, and an excess based on the carboxyl groups of the acid components, of a polyalkylene polyamine, and plastisols suitable for such a process.

Method for making coatings and adhesive bonds with polyvinyl chloride

Amine compounds, adaptable to use as a hardener for epoxy compounds, prepared by the reaction, with amine exchange and liberation of secondary amine, of a Mannich base and a member selected from the group consisting of aminoamides, aminoimidazolines, aminoamides containing an imidazoline group, and polyamines, said Mannich base being prepared by reacting formaldehyde, a monophenol or polyphenol, and a secondary amine are disclosed, as are a method of making epoxy polyadducts (i.e. cured epoxy resins) by the reaction of said amine hardener compounds with an epoxy compound and the epoxy polyadducts (i.e. cured epoxy resins) so prepared.
