Coated sand

Coated sand is a kind of high-quality selected natural sand as the sand base, resin coating system with special performance and the most ideal process technology. According to the technical requirements of different users, it strives to perform at room temperature, high temperature performance, collapsibility, and flowability. The most perfect combination of performance, casting surface roughness, etc., is widely used in automobile engines, diesel engines, hydraulic parts and other industries.
