Master Bond, Inc. Non-Drip, Polysulfide Based Two Component Adhesive EP21TPND-NV

Master Bond Polymer Adhesive EP21TPND is a two component polysulfide/epoxy based adhesive/ sealant formulated to cure at room temperature or more rapidly at elevated temperatures, with a 100 to 100 mix ratio (A/B) by weight. It readily develops a high bonding strength of more than 1000 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/Sealant EP21TPND can be applied without sagging or dripping even on vertical surfaces. It produces durable high strength and tough, flexible bonds and seals 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 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 EP21TPND adhesive/sealant is widely used in the electronic, electrical, computer, construction, metalworking, appliance, automotive and chemical industries. EP21TPND and related systems have been successfully used as fuel tank sealants for years! The cured compound fully meets the requirements for polysulfide/epoxy type sealants. It is also available as a flowable liquid of moderate viscosity; EP21TP (viscosity 50,000 cps), or a lower viscosity (5,000 cps) system called EP21TPLV.
