Alcohol based coatings

Due to its versatility, VELVACOAT is an ideal coating for multiple applications and metal types. It was engineered specifically to mitigate burn-in and penetration defects. Additionally VELVACOAT coatings provide excellent casting surfaces. They can be used for multiple applications.

 

Benefits

- Fewer casting defects and excellent casting surfaces

-  Very fast drying and flammable

-  Available in cooler burning formulations

-  Universal coating

 

Highlights

Avoiding burn-in defects

The superior refractoriness of VELVACOAT coatings for iron and steel castings makes it an exceptional solution for avoiding burn-in defects. VELVACOAT prevents the chemical reactions that cause this defect. VELVACOAT is a highly protective barrier between sand and molten metal.

 

Zircon-free coatings for heavy iron and steel applications

ASK Chemicals has developed an innovative zircon-free refractory combination for heavy and thick-walled iron, as well as steel castings. In such extreme applications, it provides the same or even better casting results as achieved with coatings containing zirconium. Two key advantages of zircon-free coatings include low density and material handling.

 

Metallurgicial coatings and sulphur stop

New types of refractory coating formulations, which bind the forming SO2 or suppress its transport from the acid cured No-Bake sand system, prevent the degeneration of graphite.
