Perma-cote 300W is a water corundum-based nonstick coating for foundry applications.
The coating is used to coat molds and cores when casting steel, gray, wear-resistant and high-strength cast irons, as well as for non-ferrous metals.
It can be used for centrifugal casting and die casting. Also, this coating is suitable for most types of binders, including furan resin, alkaline-phenolic binder and liquid glass.
Application
It is recommended for steel, cast iron and non-ferrous castings. Before use the paste should be diluted with a proper quantity of water, depending on the way the coating is applied:
- by brush,
- by spraying.
It is important that the coating is homogeneous and is held constant during use.
Coated cores and moulds are dried in the air or in an oven (up to 120⁰C).
