Foundry coatings can be thought of as paints especially developed for the metal casting industry. The difference between conventional paints and a foundry coating is that the foundry coating is designed to withstand the high temperatures of molten metal and to act as a barrier between molten metal and a core or mold surface. Foundry coatings are also referred to as refractory coatings, protective coatings, washes, and blackings, even when the coating is not black. All foundry coatings are suspensions of a high temperature mineral or refractory in a liquid carrier. After being applied to a core or mold surface the liquid is removed by evaporation and a layer of refractory is left on the sand surface. This layer or barrier can prevent or minimize the penetration of molten metal into the sand, can reduce or prevent “burn-on” and erosion of the sand and generally improves the quality of a casting surface.
Foundry coatings are widely used in various castings.
How to use:
V casting process, when the pattern(with vent holes) is covered with a heated film, and then spray our products.
Benefits of VPC Coating:
Reduce or eliminate metal penetration
Reduce or prevent “burn-on”
Prevent erosion of sand by molten metal
Smoother surface finish
Improve overall casting quality
Lower cleaning costs
Increased Pattern Life (no wear of pattern)
Very Easy Knock-out, within no time
Casting Defects is zero
