Master Bond (Hackensack, NJ) UV17Med is a one part, no mix, UV curable system. It was specially formulated to provide excellent adhesion to many TPUs (thermoplastic polyurethanes), which are widely recognized as challenging substrates for bonding. This compound provides very good toughness with a high elongation of 50-60%. UV17Med passes stringent ISO10993-5 cytotoxicity standards.
UV17Med cures in 10-30 seconds when exposed to a UV light source emitting at a wavelength of 320-365 nm with an energy output of 20-40 milliwatts/cm2. It is recommended that one of the surfaces to be bonded is transparent, without UV blocking agents, so as to allow the light to penetrate the substrate’s surface with no shadows. This flowable system features a low viscosity of 500-3,000 cps, a tensile modulus measuring between 30,000-50,000 psi, and a service temperature range from -80°F to 250°F.
