Food Container Coating
Description:
The food container coating is composed of epoxy resin, special auxiliary, solvents, epoxy hardener, polyamide resin, pigments and fillers, etc with two-component packed. It is packaged as component A and component B, with the component B being universal hardener for primer and finish coat. The macromolecule food container coating is feathered in excellent water, oil and chemical resisting properties. In the meanwhile, with strong adhesion and abrasion resistance ability, the non-toxic, odorless paint film of this food container coating proves to be sanitary paint, and it meet the standard tested by the national academy of preventive medicine as per procedures for food toxicological assessment.
Applications
This macromolecule food container coating is mainly used for inner walls of drinking water tanks, fresh water tanks, dry cargo holds, granaries, as well as internal walls of tanks, pipelines, and warehouses in the beer, beverage, food, medicine, and tap water industries, to name a few.
