EPIKOTE™ Resin 828

Description

EPIKOTE Resin 828 is a medium viscosity liquid epoxy resin produced from bisphenol A resin and epichlorohydrin. It contains no diluent. EPIKOTE 828 provides good pigment wetting and good resistance to filler settling and a high level of mechanical and chemical resistance properties in cured state. However, as an unmodified pure bisphenol A resin, EPIKOTE 828 is prone to crystallise on storage, particularly in cold conditions (see bulletin EK 1.5.11 for a description of the laboratory test method used to determine the crystallisation tendency of EPIKOTE resins). Note, EPIKOTE 827, 828 and 828 LVEL are unmodified resins of similar type and performance; they offer the formulator a choice of viscosity.
