Resin Coated Sand

Coated sand made by Kupper uses high-quality natural quartz sand as raw sand, thermoplastic phenolic resin, methenamine and enhancers as raw materials. Depending on the technology needs of users, the curing speed, stripping, flowability, collapsibility, the casting surface finish, storage can be adjusted and matched appropriately. It is one of the best moulding sand for cars, tractors and hydraulic parts.

1. Vibration sand cleaning, high strength, low gas, low expansion;
2. Lax, good casting surface finish;
3. Burly mould shell surface, good thermal stability, good thermal conductivity, good liquidity, smooth casting surface;
4. High strength, high temperature, less expansion, good mold release, no sand sticky;
5. Uniform shell layer, fast curing;
