EPON 813
Low Viscosity Liquid Bisphenol-A Based Epoxy Resin Diluted With Cresyl Glycidyl Ether, Reacts With Full Range of Curing Agents At Low Temperatures
EPON 813 is a low viscosity liquid bisphenol-A based epoxy resin diluted with cresyl glycidyl ether. EPON 813 provides several benefits compared to higher viscosity resins. It is easier to handle and flows out and wets surfaces better. In addition, entrained air escapes more easily from systems during cure, producing almost bubble-free products. Higher concentrations of filler can be used with EPON Resin 813 giving cured systems reduced cost, lower cure shrinkage, lower coefficient of thermal expansion and higher compressive strength. EPON Resin 813 can be used with all of the curing agents, common to EPON Resin 828 systems. This permits a full range of curing temperatures, pot life and handling characteristics to choose from. EPON Resin 813 systems give excellent service at moderate temperatures for long periods. They are commonly used in formulations for electrical castings and encapsulations and adhesives. They are especially useful in contact and pressure vacuum bag laminating, giving superior wet out and glass loading of up to 70%. They provide high adhesive strength to a variety of metal and non-metal surfaces. The rapid room temperature cure of EPON 813 with aliphatic amines makes it ideal for adhesives for fabrication, tooling, grouting compounds, and high solids and solventless coatings.
