Phenolic No Bake Resin (Acid Set)

COOLSET – 1001

COOLSET 1001 is a completely nitrogen free Phenolic resin, activated with acid catalyst and used in production of steel, alloy steels and sophisticated iron
castings, specially those which are prone to subsurface NITROGEN PINHOLING.The product is highly recommended for use in thick section castings as it offers high hot strength, excellent scratch hardness at high temperature, resistance to metal penetration and mould dilation.
