Description for Henkel Armstrong A-2 Epoxy Resin w/ E Activator
An off-white, versatile, filled paste resin that has low coefficient of thermal expansion making it ideal for bonding porcelain, glass and ceramics. Exhibits excellent wetting properties and provides strong bonds to rigid materials. Versatility is achieved by selecting one of four recommended activators. Non-metallic oxide fillers provide excellent electrical insulation properties.Brand Armstrong Chemical Resistance Acetone, Chemical Resistance: Glacial Acetic Acid, Chemical Resistance: Fluid Resistance: Salt water, Hexane, Chemical Resistance: Fluid Resistance: Ammonia, 28%, Distilled Water, Ethyl Acetate, Ethylenedichloride, Toluene Application Type Bond 1 Part or 2 Part 2-Part Material Form Paste Substrate Acrylics, Aluminium, Ceramics, Copper, Glass, Nylon, Polycarbonate, Polyester, Steel, Wood, Cast iron, Titanium, Magnesium, Phenolics, ABS Industry Electrical Manufacturer Henkel Chemistry Epoxy Cure Method 2 Parts Cure Temperature (°C) 93 Cure Time (min) 60 Viscosity (cPs) 5,000, 5.00 to 15, 170,000 Color Off White, Bronze High Temperature Resistance (°C) 82 Low Temperature Resistance (°C) -51 -
