Master Bond's UV15DC80-1Med is a one-component, no-mix epoxy that offers a dual cure mechanism utilizing UV light for initial fixation followed by heat for complete polymerization.

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, and meets ISO 10993-5 cytotoxicity standards, demonstrating biocompatibility for medical device applications. Is said to have excellent resistance to radiation, liquid sterilants and autoclaving. Has a moderate viscosity of 20,000-40,000cps for versatile dispensing and delivers strong bonds to various substrates, including metals, glass, ceramics, and many plastics, with a tensile strength exceeding 5,000psi at 75°F. Offers a wide service temperature range from -80°F to +350°F (-62°C to +177°C) and a high glass transition temperature of 125-135°C, and maintains optical clarity with a refractive index of 1.52 at 589nm. Exhibits minimal sensitivity to oxygen, and initial UV cure/tack can be achieved in seconds with UV light (325-365nm) at a minimum UV radiation intensity of 20-40mW/cm2 while areas with limited UV access need to be subsequently cured with heat at 80°C within 40-60 min. Post-cure at 80°C for 2-4 hr. or 125°C for 30-60 min. is recommended for maximum performance.
