Marking Master Bond’s latest offering to the medical industry, Master Bond UV15DC80-1Med offers a unique dual cure mechanism – utilising UV light for initial fixation of the epoxy followed by heat for complete polymerisation of the material. This method addresses limitations of traditional UV adhesives by effectively curing shadowed areas that wouldn't receive sufficient UV exposure, making it suitable for intricate parts and complex geometries.
Notably, the adhesive meets ISO 10993-5 cytotoxicity standards, demonstrating biocompatibility for medical device applications. UV15DC80-1Med has excellent resistance to radiation, liquid sterilants and autoclaving. This one part, no-mix epoxy has a moderate viscosity of 20,000 cps – 40,000 cps for versatile dispensing. It delivers strong bonds to various substrates, including metals, glass, ceramics, and many plastics, with a tensile strength exceeding 5,000 psi at 75°F (23.8ºC). Also, the cured adhesive offers a wide service temperature range from -80°F to 350°F (-62°C to 177°C) and a high glass transition temperature of 125ºC – 135°C. Additionally, it maintains optical clarity with a refractive index of 1.52 at 589Nm.
As a cationic system, UV15DC80-1Med exhibits minimal sensitivity to oxygen. The initial UV cure/tack can be achieved in seconds with 325Nm – 365Nm of UV light at a minimum UV radiation intensity of 20-40 mW/cm2. Areas which haven’t received significant UV exposure can then subsequently be cured with heat at 80°C within 40 – 60 minutes of the first curing stage. To maximise performance, Master Bond recommends a post cure at 80°C for 2 – 4 hours or 125°C for 30 – 60 minutes.
UV15DC80-1Med is available in various container sizes, ranging from a ½ pint to 5 gallons, to suit project needs. It's also offered in convenient 30cc syringes for manual or automated dispensing.
