Master Bond Inc., Hackensack, NJ recently announced the development of a special dual cure (UV/heat curable) epoxy system called UV15DC80. It is designed for bonding, sealing, coating and potting applications. According to the company:

  • This compound has a low viscosity, is easy to apply and requires no mixing.
  • Environmentally friendly, it is 100% solid and contains no solvents or volatiles.
  • UV15DC80 is not inhibited by oxygen and has low shrinkage upon cure.
  • A salient feature is that UV15DC80 can cure in shadowed areas by supplemental heat curing at 80°C for 15-30 minutes. Straight UV curing can be accomplished for thicknesses of .010"/.020" in seconds using UV light at 365 nm with 30-40 milliwatts per cm² of energy. Faster cures can be achieved at higher energy outputs. Post curing at 125-135°C for 15-30 minutes can increase the Tg from 90°C achieved by straight UV cure to over 130°C.
  • UV15DC80 has high physical strength properties. Adhesion to metals, glass, ceramics and most plastics is excellent. It has superior chemical resistance. Shore D hardness is >70 and its elongation after cure is 3-4%. UV15DC80 has a tensile strength of >4,200 psi and a tensile modulus of 120,000 psi. Its refractive index is 1.517.
  • Storage stability of UV15DC80 is 6 months at room temperature in the original unopened containers. It is available for use in half-pint, pint, quart, gallon, and 5 gallon pail containers. For ease of use, it also is available in syringe applicators.
