GUN 39A

GUN 59A
Dry gunning mix based on the same raw materials as HASLE Low Cement Castable D59A and D59A-EF which combines the best refractory proper­ties from several natural high-alumina raw materials, including andalusite and mullitized bauxitic clay and hence exhibits similar per­formance.

GUN 20SC
Low cement Gunning castable based on Chamotte and Silicon Carbide. Based on the proven and successful GUN39A this product from HASLE is well suited for GUNNING application where alkali resistance is required in combination with the added thermal stability and resistance to slag build-up provided from Silicon Carbide.

Two very important points when gunning, the workability of the product, and the ability to stick to the surface leaving as little spillage as possible. HASLE has been successful in both areas. The low cement gunning products are easy to ap­ply at all angles including the ceiling. The rebound rate is as low as: 10-12%.
