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.
Features
