HR COIL COAT

Description A high density plastic alumina refractory. It has high strength and abrasion resistance and good electrical insulation once dried.
Installation Supplied as powder, to which 12 to 13% water must be added for a stiff putty consistency, or more water for a soft coil embedding consistency.
Applications Areas where combinations of high strength, abrasion resistance, high thermal conductivity and zero electrical conductivity are required. Main uses are; filling the spaces between induction coils, Embedding elements around muffles.
