Gilsonite In Foundry
Physical Sand properties with Gilsonite resin are equal or superior to sea coal at significantly lower additive levels.
Gilsonite "Natural Asphalt" improves sand density, water requirements and strength (green, dry, baked, and hot). Gas evolution curves show that Gilsonite "Natural Bitumen" volatilizes more rapidly than sea coal. Gilsonite has the same total volatiles as sea coal at one-third the additive level.
Principal Applications
Foundry Sand Additive
Refractaries
Ingot Mold Coating
