Abstract

The invention relates to a solvent-free epoxy coating which includes following components, by weight: 200-300 parts of low-molecular-weight epoxy resin, 50-60 parts of a reaction active diluent, 30-45 parts of a coloring pigment, 15-20 parts of an anti-settling agent, 5-7 parts of a defoaming agent, 3-9 parts of a dispersing agent and 5-12 parts of a low-viscosity amine curing agent. The epoxy coating is prepared from the low-molecular-weight epoxy resin, the coloring pigment, the additives and the like through high-speed dispersion and grinding. The epoxy coating is a double-component reaction curing anti-corrosion coating with the low-viscosity modified amine as the curing agent. The epoxy coating is scientific in formula, is high in safety and is excellent in construction safety and environmental protection.

Description
