Molecular Structure:
Sinepoxy® CER-221 OXT is a 双官能 oxetane 单体 engineered for high-performance cationic UV光固化 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 单体 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 低挥发性 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光固化 inks, coatings, adhesives, 3D printing materials, and optical films.
