Master Bond Polymer Adhesive EP21D-1 is a two component epoxy adhesive for general purpose bonding formulated to cure at room temperature or more rapidly at elevated temperatures, with a conveninet two-to-three mix ratio, weight or volume. It readily develops a high bonding strength of more than 3000 psi at room temperature which unlike that of many other epoxy adhesives, is relatively insensitive to mixing ratio or substrate cleaning procedures. Master Bond Polymer Adhesive EP21D-1 can be applied without sagging or dripping even on vertical surfaces. It produces durable high strength, flexible, tough bonds and seals with high peel strength which are remarkably resistant to thermal cycling and chemicals including water, oil and most organic solvents, over the exceptionally wide temperature range of -60°F to more than 250°F. Adhesion to metals, glass, ceramics, wood vulcanized rubbers and many plastics is excellent. The hardened adhesive/sealant is an electrical insulator. Color of part A gray, part B amber. Master Bond EP21D-1 adhesive is widely used in the electronic, electrical, computer, construction, metalworking, appliance, automotive and chemical industries. The EP21CL-1 version is especially designed for concrete bonding.
