Abstract
A water-based coating composition and methods of making and using the same are disclosed. The composition includes a halogenated resin, a polyol, a surfactant, and an amine. It is suitable for coating a variety of substrates including polyolefinic substrates such as polypropylene, and operates without aromatic organic solvents.
Claims21
An aqueous coating, composition, comprising effective film-forming amounts of:
- (a) about 0.5 to about 40 parts by weight of a thermoplastic polyolefinic resin, said resin having a molecular weight up to about 40,000, or a softening point of about 150.degree. F. to about 350+ F.;
- (b) at least one constituent selected from the group consisting of a polyol in an amount up to about 40 parts by weight, a surfactant in an amount up to about 15 parts by weight and mixtures thereof;
- (c) about 0.01 to about 10 parts by weight of an amine having an amine functionality of between 1 and 3;
- and
- (d) the balance water, wherein said composition is substantially free of aromatic organic solvents.

An aqueous coating composition, comprising effective film-forming amounts of:
- (a) about 0.5 percent to about 40 percent of a resin selected from halogenated polyolefinic resin materials, halogenated vinyl resins, epihydrin resins, halogenated epoxy resins, and mixtures thereof, said resin having a molecular weight of about 10,000 to about 30,000, or a softening point of about 150.degree. F. to about 350.degree. F.;
- (b) at least one constituent selected from the group consisting of a polyol in an amount up to about 40 parts by weight, a surfactant in an amount up to about 15 parts by weight and mixtures thereof;
- (c) about 0.01 to about 10 parts by weight of an amine having an amine functionality of between 1 and 3;
- and
- (d) the balance water, wherein said composition is substantially free of aromatic organic solvents.
