Molecular Structure:
Sinepoxy® CER-221 OXT is a bifunctional oxetane monomer engineered for high-performance cationic UV-curable systems. It features two reactive oxetanyl groups that undergo cationic ring-opening polymerization. Characterized by its exceptionally low viscosity, it provides excellent diluting power and enhances formulation flow and processing ease.
This monomer contributes to rapid curing speeds and low shrinkage upon polymerization. As a cross-linking component, it helps to form polymer networks that can be tailored to achieve a favorable balance of hardness and toughness, along with strong substrate adhesion. These properties, combined with its low volatility and favorable toxicological profile, make it a reliable and effective component in formulations designed for chemical resistance and elevated temperature performance.
Sinepoxy® CER-221 OXT is widely used in demanding applications such as UV-curable inks, coatings, adhesives, 3D printing materials, and optical films.
