One and two component cured epoxy resin systems provide hydrolytically stable bonds after prolonged aging. These easy to apply, ROHS compliant compounds resist decomposition when exposed to high humidity and temperatures. Products resist mildew/fungus and prevent softening, chalking, blistering, discoloration, brittleness and disintegration. Adhesive strength properties are maintained after outdoor serviceability in tropical environments. Systems guard against corrosion and abrasion. Hydrolytic stable epoxies are frequently employed in potting/encapsulation applications. Premium performance epoxies feature excellent dielectric properties. They have long working life, low exotherm and can fill small voids without entrapment of air.
