Master Bond, Inc. UV Curable Compound UV15-7TK1ANV Features Paste Consistency UV15-7TK1ANV

Master Bond Polymer System UV15-7TK1ANV is a new one component, high viscosity, optically clear, tough UV curable polymer system with extended capability of -80°F to +300°F. It is fully reactive, does not contain any solvents or other volatiles and does not embrittle even upon exposure to low service temperatures. When exposed to a source of UV light of appropriate wave lengths and adequate intensity, it cures quickly to produce a tough, durable, non-yellowing, and chemically resistant adhesives, sealants and coatings, with excellent electrical insulation properties. The UV cured polymeric material features low shrinkage, excellent adhesion to various substrates, hardness and durability in thick sections up to 200 mils and more. Unlike any other commercially UV curable products, the high viscosity Master Bond UV15-7TK1ANV polymer system is not inhibited by air and exhibits a desirable fast curing rate at ambient temperatures even at section thickness greater than 1/4". Cure time depends on the type of UV lamp, the wave lengths and the amounts of the UV15-7TK1ANV, the thickness of the section to be cured, etc. Typical cure times range from as little as 5-10 seconds to 1-2 minutes at ambient temperatures. Commercially marketed 200 watt/inch medium pressure mercury vapor or equivalent UV light sources are recommended. Maximum UV absorption takes place in the 280-360 nanometer range. No solvents or other vapors are released during the curing process which takes place with minimal shrinkage from the liquid to the solid state. Cured adhesives, sealants and coatings exhibit a most desirable performance profile including outstanding durability, toughness, thermal shock resistance, flexibility, non-yellowing color as well as excellent adhesion to many substrates ranging from glass and steel to polyester films and polycarbonates.
