New Polymer System Cures by UV Light and/or Heat

Master Bond Inc., Hackensack, N.J. has introduced a new one component, optically clear, non-yellowing UV and/or heat curable polymer system called UV15-7DC. This high performance system is designed for bonding, sealing and coating applications. It is 100% reactive and does not contain any solvents or other volatiles. UV15-7DC is not inhibited by air and exhibits a desirably fast UV cure at ambient temperatures. Typical cure times range from 5 seconds to 2-3 minutes depending upon the wave length, intensity of the UV light and the thickness being cured. Typical heat curing schedules are 10-30 minutes at 250-260°F. Heat curing is recommended for use in applications with “shadowed out areas”.

Master Bond UV15-7DC is easy to use and has a low viscosity. It has outstanding durability, toughness, thermal shock resistance as well as excellent adhesion to many different substrates. These substrates include glass, metals, plastics, polyester films and polycarbonates. It has a Shore D hardness of >70 and an elongation of 65-75%. Its tensile strength is 5,460 psi.

Master Bond UV15-7DC is available in pint, quart, gallon and 5 gallon containers. For ease of application it also is available in syringe applicators.

Note: Starting from February 2017 Master Bond offers a new version of this formulation called UV15-7DCNV, while UV15-7DC has been discontinued.
