Key Features of Coated Sand

1. Vibration sand cleaning, high strength, low gas generation, and low expansion;

2. Good dispersion and high surface smoothness of castings;

3. The shell type has no delamination, good thermal stability, good thermal conductivity, good fluidity, and a smooth surface of the casting;

4. High strength, high temperature resistance, low expansion, good demolding performance, and good resistance to sand sticking;

5. The shell layer is uniform and does not peel off, and the curing speed is fast.
