Liquid Epoxy Resin (Bisphenol A Type) CAS 25068-38-6 - Industrial Grade Thermosetting Polymer

Bisphenol A Type Liquid Epoxy Resin (DGEBA, CAS:25068-38-6,EINECS:293-777-5, HS Code:3907300000, molecular formula (C₁₁H₁₂O₃)ₙ) is a colorless to pale yellow transparent viscous liquid produced via condensation reaction of bisphenol A with epichlorohydrin under alkaline conditions. Our industrial grade epoxy resin is available in two mainstream specifications: E-51 (128/618) and E-44 (6101), featuring high epoxy value, low viscosity and excellent reactivity. When cured with amine or anhydride curing agents, it forms a three-dimensional crosslinked network with outstanding mechanical strength, adhesion, chemical resistance and electrical insulation properties. As the most versatile thermosetting polymer, it is widely known as the "universal industrial resin" and serves as the foundational material for adhesives, coatings, electronic components and composite materials. Our product strictly complies with GB/T 13657-2012 and international industrial standards, ensuring consistent batch quality.
