CAST BOND

Cast Bond is a blend of high quality VOLCLAY and PROBOND at a suitable ratio. Blended bentonites are commonly used in industrialized countries such as USA,
Australia, Canada, U.K., Mexico, and European countries. Blended bentonites comprise 80% of the USA ferrous foundry market.

Volclay Siam is proud to present Cast Bond as an advanced product so that foundries can access current bentonite technology at competitive costs. Those foundries seeking to improve quality with improved bentonite formulation now have
a local supply to meet their ever-increasing demands. By drawing on American Colloids vast experience with blended materials, Volclay Siam can now extend to the Thai foundries precision blending of premium bentonites. Extensive testing
in our laboratory with 4 parts VOLCLAY to 1 part PROBOND indicates improved properties.

Major reasons that Cast Bond is number one in the international market :

• Reduce Inventory Costs: Foundries that blend two bentonites, can minimize inventory management problems
by stocking only one product instead of two.

• No need to worry about inconsistencies in mixing ratios as Cast Bond is blended with precision accuracy at the
Volclay Siam production facility.

• Higher GCS are achieved from better flowability of the mixture thus achieving greater mold density from the
inherent properties of calcium bentonite.

• Lower DCS leading to easier shake out and less lumping of the return sand.

• Calcium Bentonites are easier to hydrate thereby reducing mulling energy.

• Competitive prices can minimize company's day to day production costs.
