Cycloaliphatic Epoxy Resin (3,4-Epoxycyclohexylmethyl-3,4-epoxycyclohexane Carboxylate)
CAS Number: 2386-87-0
Cycloaliphatic Epoxy Resin is a low-viscosity, aromatic-free difunctional epoxy offering exceptional UV stability and outdoor durability. Unlike aromatic epoxies, it resists yellowing and chalking under UV exposure, making it suitable for outdoor coatings, optical adhesives, and UV-curable systems. Cured systems exhibit high Tg, excellent electrical insulation, and very low moisture absorption.
