Master Bond UV22DC80-1 is a one component, low viscosity, nanosilica filled epoxy based system for bonding, sealing and coating with the ability to cure under UV light and/or with heat. The UV portion of the cure can be achieved in seconds upon exposure to a UV light at 365 nm with 20-40 milliwatts/cm2 of energy. This type of formulation allows for polymerization in “shadowed out” areas with the addition of heat at 80°C for 40-60 minutes. This advantageous low temperature is useful when working with plastics or other heat sensitive substrates.
