UV15DC80-1 Product Information

Master Bond UV15DC80-1 is a special dual cure epoxy based system which offers a primary cure utilizing UV light along with a secondary heat curing mechanism. This system addresses the problem of curing areas on parts that do not allow UV light curing because of shadowing issues. Heat can be used not only to complete cure, but to initiate fixturing. Also, the decrease of fixturing time to seconds is highly advantageous in a production environment, or when fixturing is a laborious and expensive proposition. One innovative use of a dual cure UV is to fixture two optically opaque substrates, such as metals, with the UV light exposure and then completing the cure with heat.

This moderate viscosity system features a cationic cure mechanism (for the UV portion) and has very low shrinkage upon curing. UV15DC80-1 is not oxygen inhibited and has outstanding chemical resistance to many acids, bases, fuels and solvents. It is a superb electrical insulator and bonds well to metals, glass, ceramics and most plastics. UV15DC80-1 has a service temperature range of -80°F to +350°F.

If there are no shadows, straight UV curing in thicknesses of 0.010” to 0.020” will usually take 10-20 seconds with UV light at 365 nm with 20-40 milliwatts/cm2 of energy. Areas not cured by shadowing, can be cured at 80°C for 60-90 minutes. Post curing for 2-4 hours will help optimize properties. If possible, 1-2 hours at 125°C will promote curing even further. The 80°C secondary cure is truly a remarkable innovation. It has wide applicability in the optical, electronic and optoelectronic industries.
