Master Bond -- UV15-7 Optically Clear UV Curable Polymer System For High Performance Adhesives, Sealants and Coatings - Master Bond - #1

Master Bond Polymer System UV15-7 is a new one component, optically clear, non yellowing UV curable polymer system for high performance bonding, sealing and coating. It is 100% reactive and does not contain any solvents or other volatiles. When exposed to a source of UV light of adequate wave length and intensity, it cures quickly to produce durable, tough, non-yellowing, chemically resistant adhesives, sealants and coatings with excellent electrical insulation properties. The UV cured polymeric material can be employed over the wide service temperature range of -60°F to +300°F (-50 to 150°C).

Unlike many other commercially curable UV curing products, the Master Bond UV15-7 system is not inhibited by air and exhibits a desirable fast curing rate at ambient temperatures even in a section thicknesses of 1/8" and more. Cure time depends on the type of UV lamp, distance of the lamp from the surface of the UV15-7, thickness of the section to be cured, etc. Typical cure times range from as little as 5 seconds to 2-3 minutes at ambient temperatures. 200 Watt/inch medium pressure mercury vapor lamps or equivalent UV light sources are recommended. Maximum UV absorption takes place in the 280-360 nanometer range. No solvents or vapors are released during the curing process. Cured adhesives, sealants or coatings exhibit a most desirable combination of properties including outstanding durability, roughness, thermal shock resistance as well as excellent adhesion to many different substrates ranging from glass, metals, plastics, polyester films, and polycarbonates. The storage stability of the UV15-7 Polymer System is 6 months under usual storage conditions in original unopened containers.
