An optically clear adhesive which produces tough, high-performance bonds, seals and coatings for an array of substrates has been developed by Master Bond for demanding bonding, coating, and sealing applications.
This non-yellowing one component adhesive is 100% reactive and doesn't contain any solvents or diluents. It also offers excellent adhesion to a wide variety of substrates including glass, metals, plastics, polycarbonates and polymer films.
Like many UV curable adhesives, UV15-7 offers fast cure rates, ranging from 5 seconds to 3 minutes upon exposure to a UV light source. Maximum UV absorption occurs in 280 to 360 nanometer range using a 200 Watt/inch medium pressure, mercury vapour lamp. Unlike many UV curable products, UV15-7 is not inhibited by air and cures quickly at ambient temperatures, even in thickness up to 1/8 inch or more.
Serviceable over the wide range of -60 to +300°F, UV15-7 features a tensile strength exceeding 5,000 psi, a refractive index of 1.55 and a Shore D hardness over 70. Resistant to chemicals and thermal shock, it features a thermal expansion coefficient of 65-70x10-6. With a volume resistivity of 1014 ohm-cm, this low viscosity adhesive offers excellent electrical insulative properties.
