A clear, one-component, non-yellowing polymer system designed for bonding, sealing, coating, and encapsulation is both UV- and heat-curable. Newly launched by Master Bond Inc., Hackensack, N.J., Master Bond UV15-7DC is a 100% reactive, urethane-modified epoxy acrylate that contains no solvents or volatiles. It has a low viscosity of 1500 to 2500 cp at 25 C, and boasts outstanding durability, toughness, thermal-shock resistance, and adhesion to many substrates, including acrylic, polycarbonate, polyester, ABS, and ASA, as well as glass and metals. It has a Shore D hardness above 70, elongation of 65% to75%, and tensile strength of 5460 psi. Unlike many other UV-curing products, this system is not air-inhibited and reportedly cures quickly at ambient temperatures, even in thicknesses of 0.125 in. or more. Typical cure times range from 5 sec to 2-3 min, depending on the UV wavelength and intensity and the thickness being cured. A typical heat-curing schedule is 10 to 30 min at 250 to 260 F. Heat curing is recommended for applications with “shadowed-out” areas that could not be reached by a UV lamp. (201) 343-8983 • www.masterbond.com
