High Quality Making Mold Core Precoated Resin Sand with Low Thermal Expansion
Description of precoated resin sand :
Precoated resin sand 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 of silica resin coated sand can be adjusted and matched appropriately.
silica resin coated sand is one of the best moulding sand for cars, tractors and hydraulic parts.

Features :
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;
Application :
Resin coated sand is a non-quartz artificial sand employed to the production of metal casting.
silica resin coated sand also can be used for many casting methods such as vacuum casting, VRH, LFC, investment casting, common and resin sand. The fused ceramic foundry sand can be with many adhesives, greatly improving the quality of castings.
1. Production of low pollution coated sand, reduce the use amount of resin and curing temperature; improve coated sand's overall performance, especially in high temperatures; research and develop of pollution-free phenolic resin alternatives.
2. Improve the regenerative capacity of coated sand.
