UV curable system with a fluorescent dye meets ISO 10993-5 testing

This feature enables visual inspection with a UV black light to detect voids or overflow and confirm product placement. Engineered for bonding, sealing, coating, and spin coating across a variety of medical device applications, this system passes ISO 10993-5 standards for non-cytotoxicity.

UV16Med-FD resists acids, bases, solvents, and sterilants including ethylene oxide and glutaraldehyde. It also withstands repeated autoclaving. The cured material is optically clear, with a refractive index of 1.511 at 75degF. Tensile strength measures 7,000-8,000 psi, and tensile modulus ranges from 250,000-300,000 psi at room temperature. A low viscosity of 250-500 cps at 75degF makes the material suitable for application by syringe or spin coating. It adheres to substrates including plastics, glass, ceramics, and metals.

UV16Med-FD is a cationic system that contains no solvents or diluents and is not oxygen inhibited. Exposure to UV light at 320-365 nm, with a minimum intensity of 20-40 mW/cm2, initiates the cure. The cure rate depends on light intensity, distance from the source, and section thickness. Post curing at 125degC for 30 minutes brings the glass transition temperature to 130-135degC, which improves autoclave resistance. The service temperature range spans -62degC to +204degC.

UV16Med-FD is available in 1/2 pint, pint, quart, gallon, and 5 gallon containers, as well as EFD syringes compatible with many automated dispensers.
