Description: |
|
Natural Bitumen Foundry Grade is for Foundry
Sand Additive Refactaries Ingot Mold Coating
Briquette or Pellet Binder, Physical Sand
properties with Gilsonite resin are equal or
superior to sea coal at significantly lower
additive levels. |
|
|
|
>>
Applications: |
|
Natural Bitumen Foundry Grade improves sand
density, water requirements and strength
(green, dry, baked, and hot). Gas evolution
curves show that Gilsonite volatilizes more
rapidly than sea coal. Gilsonite has the
same total volatiles as sea coal at
one-third the additive level. |
