• Low free isocyanate prepolymers enable final formulations with reduced hazard classifications, especially for consumer and contractor uses
• Low volatile organic solvent content reduces toxicity and flammability risks for contractors and building owners
• Compatibility with low odor solvents reduces the nuisance to building users
• Formulations can be designed for specific reactivity and cure profiles
• Prepolymers can be formulated as 1K or 2K systems for use in all seasons to provide excellent mechanical properties and UV stability, even when exposed to the environment

Blocked Aromatic Prepolymers used as Epoxy Flexibilizers for Coatings and Adhesives

Epoxy resins have excellent properties and are widely used in corrosion protection coatings and flooring applications. Due to their high mechanical rigidity they can be brittle and tough, therefore need to be flexibilized to suit specific applications including; industrial and antibacterial flooring, parking decks and flooring adhesives. Trixene^® blocked urethane prepolymers improve flexibility and impact resistance of epoxy coatings, without compromising chemical resistance. These blocked prepolymers readily react with standard amine hardeners used in 2K epoxy resin formulations, allowing permanent flexibilization of the end product.
