Abstract

Two component water-based coatings, inks, adhesives and sealants prepared by reacting enhanced molecular weight epoxy emulsions with amine curatives.

Claims

1. A heat hardening or air drying two component water-based composition suitable for making a reaction product for use as a coating, ink, adhesive, or sealant, comprising:

Part A and Part B components;

said Part A component comprising an enhanced molecular weight epoxy ionic emulsion; and

,

said Part B component comprising an amine chosen from the group consisting of primary, secondary and tertiary amines or ammonia, said enhanced molecular weight epoxy polymer being prepared by polymerizing water-borne epoxy resin particles in the presence of an alkaline substance.

2. An article having a metallic, cementaceous, wood, paper, or fiber surface coated with a heat hardening or air drying film of a composition comprising:

the reaction product of a mixture of Part A and Part B components;

said Part A component comprising an enhanced molecular weight epoxy ionic emulsion; and

,

said Part B component comprising an amine chosen from the group consisting of primary, secondary and tertiary amines or ammonia,

said enhanced molecular weight epoxy polymer being prepared by polymerizing water-borne epoxy resin particles in the presence of an alkaline substance.

3. Articles having metallic, cementaceous, wood, paper, or fiber surfaces which are bound together with a heat hardening or air drying composition comprising:

the reaction product of a mixture of Part A and Part B components;

said Part A component comprising an enhanced molecular weight epoxy ionic emulsion; and

,

said Part B component comprising an amine chosen from the group consisting of primary, secondary and tertiary amines or ammonia,

said enhanced molecular weight epoxy polymer being prepared by polymerizating water-borne epoxy resin particles in the presence of an alkaline substance.
