Master Bond Polymer system UV15-7NV 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. Unlike many other commercially curable UV curing products, the Master Bond UV15-7NV 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 UV15-7NV, 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 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, polye[JB1]ster films, and polycarbonates. The storage stability of the UV15-7NV Polymer system is 6 months under usual storage conditions in original unopened containers.
