REFRACTORIES & COATINGS

 
Refractories are durable materials engineered to withstand extreme temperatures without breaking down, making them essential for lining furnaces, ladles, molds, and other equipment used in casting iron, steel, aluminum, and other alloys. They retain heat to maintain the proper temperature of molten metal and endure rapid heating and cooling cycles without cracking or degrading.

Core and Mold Coatings

Refractory coatings are applied to molds and cores to improve the surface finish of the castings and minimize defects that can occur at the sand-metal interface. These coatings provide a higher melting point than the sand and create an impermeable barrier between the sand grains and the molten metal.

The refractory system is the most critical coating component, directly determining the coating's overall effectiveness. The type, shape, size distribution, thermal expansion, chemical reactivity, thermal conductivity, and specific gravity are the basic criteria for the selection of the proper refractory.

Coatings developed by ASK Chemicals are far more than a pure barrier between sand and metal. They are high performance systems and determine in a decisive way the accuracy and surface quality of the casted parts and thus specifically eliminate typical casting defects. Whereas all coating systems are characterized by excellent casting results, low cleaning and fettling efforts as well as productivity and efficiency in the casting process, ASK Chemicals water-based coatings offer unbeatable advantages.
