SU753875A1 - Water-diluting epoxy composition for coatings - Google Patents

Description

This goal is achieved in that the water-soluble epoxy composition for coatings, including epoxy cyan gum, pigments, hardening agent and water, contains a mixture of polyamino amide resin and aromatic primary amine selected from the group containing the adduct of formaldehyde and ethylene diamine to phenol, xylylenediamine, its adduct with diphenylolpropane glycidyl ether, in a ratio of 1: 0.05-0.16, with the following ratio of components, parts by weight: Dianova epoxy resin1 0O

Pigments56, -95

A mixture of a polyaminoamide resin and an aromatic primary amine selected from the group: a product of addition of formaldehyde and ethylene diamine to phenol; xylylenediamine; its adduct with diphenyl glycidyl ether .. lolpropane in the ratio of 1: 0.05-0.16 50-100 Voda70-245

The proposed water-borne epoxy composition is a two-pack, one of its components is pigmented Diane epoxy resin, and the other is an aqueous solution of an oral emulsifier.

The hardener-emulsifier is obtained by mechanical displacement of the polyaminoamide resin and the aromatic primary amine.

The emulsifier hardener is a pale yellow to dark brown liquid with a viscosity of 1 to 4OO P and may have a faint smell of amine.

Pigmented epoxy resin was prepared by grinding the pigments with epoxy resin. Then see both components of the composition.

The composition uses inorganic pigments: titanium dioxide, red iron oxide pigment, crown oxide, strontium, lead silico chromate, chromium oxide, etc.

In the composition, you can enter fillers: talc, mica, blanfix.

The composition can be applied by brush or by spraying onto a metal or concrete surface.
