Master Bond has released a new biocompatible and UV curable adhesive, specifically formulated for adhesion to thermoplastic polyurethanes (TPU), which are widely recognised as challenging substrates for bonding.
Master Bond UV17Med is a one part, no mix, UV curable system and the compound provides good toughness with a high elongation of 50% - 60%. UV17Med cures in 10 - 30 seconds when exposed to a UV light source emitting at a wavelength of 320Nm – 365Nm 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, as to allow the light to penetrate the substrate’s surface with no shadows. This flowable system features a low viscosity of 500cps – 3,000cps, a tensile modulus measuring between 30,000psi – 50,000psi, and a service temperature range from -80°F (-62°C) to 250°F (121°C).
This non-cytotoxic system was designed for demanding applications in the medical industry and can withstand 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.
The product is available in a wide range of packaging options, including ½ pint, pint, quart, gallon and five gallon containers. It can also be purchased in convenient syringe applicators for automated dispensing. UV17Med passes ISO10993-5 cytotoxicity standards.
