Master Bond adhesives

Master Bond EP21TDC Toughened, Shock Resistant Two Component Epoxy System
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Master Bond Polymer Adhesive EP21TDC is a two component epoxy adhesive for general purpose bonding formulated to cure at room temperature or more rapidly at elevated temperatures, with a one-to-one mix ratio, by weight or volume. It readily develops a high bonding strength of more than 2800 psi at room temperature which unlike that of many other epoxy adhesives, is relatively insensitive to mixing ratio or substrate cleaning procedures.

Vendors: Master Bond is a leading manufacturer of adhesives, sealants, coatings and potting compounds. Master Bond’s vast product line consists of over 3,000 epoxy, polyurethane, silicone, cyanoacrylate and latex adhesives that vary in viscosity, cure speed, strength, chemical resistance, electrical properties, etc. Our custom adhesives offer design flexibility and provide excellent bonding performance.
