Increase Durability & Strength
IKOBOND® is the newly developed patent pending clay technology designed for superior durability for high density molding.
This new clay has shown increased durability with respect to Green Compression Strength and Wet Tensile Strength. The strengths generated allow quicker sand development, optimizing consumption usage of bond per ton of metal poured.

Get Both Core & Mold Benefits from ANTRAPEX® Sand Additive
Better Finishes. Reduced Defects. Good Recyclability.
ANTRAPEX® is a service-proven core sand additive that positively influences both the core and the bentonite-bonded molding material. The additive is mixed with core sand and thus contributes to reducing expansion and penetration defects. After core breakdown, ANTRAPEX® passes into the molding material where it has a positive effect on the casting surface and sand stability. ANTRAPEX® is a blend of organic and inorganic components. The core sand additive has been developed by IMERYS especially for the PUR Cold Box process.
- Casting surfaces of near-perfect finish
- Reduce expense in terms of core coating operations
- Following core breakdown, the residues develop lustrous carbon
- Good recyclability
- Reduced gas formation from the core
RIKO© - Recovery of Bentonite & Carbon From Foundry Dust
A Unique Process Technology
Foundry Dust Collection and the Loss of Beneficial Materials
Bentonite and carbon have long been used as key components in the green sand casting process. In 2018 United States Foundry Industry consumed approximately 700,000 tons of bentonite and carbon.
Silica sand has been used in the green sand process for hundreds of years. Recently the United States Environmental Protection Agency instituted tighter regulations on the Permissible Exposure Limits for silica sand dust. This has meant an increased focus on, and need for additional ventilation and dust collection. While this ventilation and dust collection reduces the amount of fine silica sand, it extracts other useable materials, such as active bentonite and carbon.
Preventing Casting Defects is Easy With IMQUICK®
Water is THE essential component in the activation of bentonite used to bond in the green sand process. While necessary to activate the clay, free moisture, not tied up in the bentonite platelet structure is the enemy of metal. If it exists, the free moisture can cause significant casting defects.
IMQUICK is a patented, bentonite based formulation which includes finely sized industrial mica for:
- Better sand flowability in the molding process
- Better compaction
- More consistent mold hardness – without the need for additional moisture
In fact, if reduced moisture is your goal, it’s possible to run lower moisture percentages with IMQUICK versus most conventional premix formulas.
