Cycloaliphatic Epoxy Resin 4221 CAS NO.2386-87-0

CER 4221 is a cycloaliphatic epoxy resin made by our proprietary epoxidation using a special catalyst system.  It is a liquid with lower viscosity than epi- and bis- epoxy resins for general purposes, and contains no halogen impurities such as chlorine.  It gives superior transparency with acid anhydride curing agents, and provides cured parts with a high heat-deformation temperature.  These properties find uses in applications such as cation or acid cured coatings, electrical-insulating varnishes and sealants for semiconductors.  It is also used as the acid scavenger for halogen compounds.
