Castorcin™ Polyol Series

The Castorcin™ Polyol Series are 100% solids castor oil-based polyol derivatives designed for use as polyols or reactive diluents in two-component (2K) polyurethane adhesives and sealant systems.  These products will allow for the formulation of high performance flexible sealants and adhesives. Castorcin Polyols are multi-functional polyols having a high level of reactivity resulting in enhanced flexibility and strength.

Applications

Filter Adhesives

Castorcin Polyol’s low viscosity allows for good flow and penetration into the filter media, while providing a durable and hydrophobic adhesive seal. It is often used in food manufacturing environments. 

Concrete Adhesives and Sealants

Chemical resistance is a critical requirement for concrete adhesives and sealants. Our polyols have excellent resistance to organic and inorganic acids, caustic, bleach, gasoline, and diesel fuel.  Castor oil polyol-based polyurethanes exhibit good thermal shock resistance and UV exposure stability. They are useful for demanding concrete and flooring applications. Many are FDA-approved for incident food contact. 

Industrial Maintenance Coatings

These polyol-based polyurethane coatings exhibit good chemical resistance to cold and hot water, organic and inorganic acids, caustic, diesel fuel, gasoline, and other commonly encountered chemicals. Castorcin Polyol-based polyurethanes exhibit UV exposure stability.
