Master Bond Polymer System UV21 is an easy to use one component UV curable urethane elastomer compound. It has been used for bonding, sealing, casting and formed in place high performance seals and gaskets. The UV21 is a solvent free system and has an excellent six month shelf life at ambient temperatures. Curing can be accomplished with UV light emitted from 320-365 nanometers. Radiation dosages of 20-40 mw/cm² can effect rapid cures; seconds for thinner sections, slightly longer for thicker ones. UV21 offers outstanding physical strength properties including elongation of over 260% and a tensile strength of over 500psi. While the UV21 has the flexibility of RTV silicones if offers many advantages including faster cure time, improved chemical resistance, and no emission of corrosive elements while curing. The temperature range of UV21 is an outstanding -65°F to 250°F and its electrical insulation properties are also superb.
