Master Bond‘s new 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 excellent toughness, with a high elongation of 50 to 60%, passing stringent ISO10993-5 cytotoxicity standards.
UV17Med cures in 10 to 30 seconds when exposed to a UV-light source, emitting at a wavelength of 320 to 365 nm with an energy output of 20 to 40 milliwatts/cm2. It’s 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 to 3,000 cps, a tensile modulus measuring between 30,000 to 50,000 psi, and a service temperature range between -80° and 250° F.
This non-cytotoxic system is formulated for demanding applications in the medical industry, and is capable of withstanding many chemicals including liquid sterilants, antimicrobial agents, Ethylene Oxide (EtO), e-beam, and gamma radiation. In addition to TPUs, UV17Med bonds well to metals, glass, ceramics, and many plastics.
It’s available in a wide range of packaging options, including half-pint, pint, quart, gallon, and five-gallon containers. It can also be purchased in convenient syringe applicators for automated dispensing.
