Highly Flexible UV Curable Adhesive Meets ISO 10993-5 Standard for Cytotoxicity

Master Bond UV15X-6Med-2LV is a UV curable, non-cytotoxic adhesive that features optical clarity and abrasion resistance. Not only can it be utilized for bonding, but it can also be employed for sealing, coating, and encapsulating purposes. It has a high degree of flexibility with an elongation that exceeds 100% and a low tensile modulus of 20,000-50,000 psi at room temperature. This flexibility allows it to withstand extreme thermal cycling and mechanical shock without inducing stress on components/parts. It bonds well to similar and dissimilar substrates including glass, metals and plastics.

UV15X-6Med-2LV is a one part system that cures upon exposure to a UV light source emitting at a wavelength of 320 to 365 nm with an energy output as low as 20-40 milliwatts/cm². It can cure in as little as 10 to 30 seconds, and in sections up to ¼ inch. A successful curing process entails complete exposure to the UV light source, for this reason there should be no shadows or UV blocking agents in the substrates used. As a one part system, it requires no mixing prior to use. This compound has a medium viscosity of 20,000-40,000 cps and is not oxygen inhibited. It is electrically insulative with a volume resistivity of more than 10¹² ohm-cm at room temperature. UV15X-6Med-2LV has a refractive index of 1.50. It is serviceable over the temperature range of -80°F to +250°F.

Since UV15X-6Med-2LV meets the ISO 10993-5 certification it can be used in medical device manufacturing applications where this requirement is vital. It has good resistance to water, cleaning agents, e-beam, ethylene oxide and gamma radiation. Packaging is available in syringes, ½ pint, pint, quart and gallon sizes.
