Master Bond UV15DC80 is a very special dual cured (UV/heat) curable system featuring the capacity to cure in shadowed out of areas by supplementary heat curing at 80°C for 15-30 minutes. In addition, UV15DC80 has outstanding physical properties including superb physical strength characteristics along with unmatched temperature and chemical resistance. UV15DC80 is 100% solids and contains no solvents or volatiles. This low viscosity system features a cationic type curing system, with low shrinkage upon curing. UV15DC80 forms high strength bonds to metals, glass, ceramics and most plastics.

UV15DC80 is not inhibited by oxygen. Straight UV curing can be accomplished for thickness of .010"/.020" in seconds using UV light at 365nm with 30-40 millwatts per cm² of energy. Faster cures can be acheived at higher energy outputs. Areas not cured because of shadowing can be cured at 80°C for 15-30 minutes. In addition, post curing at 125-135°C per 15-30 minutes can increase the Tg from 90°C achieved by straight UV cure to over 130°C with a post cure. The storage life in unopened container at ambient temperature is 6 months.
