Welcome to our website! SH Chemical Group Co.,Ltd is a professional food container coating manufacturer and supplier located in China. Here, in the following, we will introduce you specifically our macromolecule food container coating, 841.

Introduction
The food container coating is a two-component paint composed of epoxy resin, special auxiliary, solvents, epoxy hardener, polyamide resin, pigments and fillers, etc. It is packaged as component A and component B, with the latter being universal hardener for primer and finish coat. The macromolecule food container coating has excellent water, oil and chemical resisting properties. With strong adhesion and abrasion resistance, the non-toxic, odorless paint film proves to be sanitary paint, tested by the national academy of preventive medicine as per procedures for food toxicological assessment.

Applications
The macromolecule food container coating is applicable to 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.
