Key Features:- Allows for curing in “shadowed out” areas
- Cures at temperatures as low as 80°C
- Convenient no mix system
- Excellent physical strength properties
Master Bond UV15DC80-10 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. Most noteworthy is that the heat cure portion can be initiated at only 80°C rather than at the more common 125°C. Another very useful feature of a dual cure UV is that it allows for rapid fixturing and then enables the cure to be completed by adding heat. As alluded to above, a secondary cure at 80°C is not very common and highly desirable because of the sensitivity of many plastics to elevated temperatures. 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 low to moderate viscosity system features a cationic cure mechanism (for the UV portion) and has exceptionally low shrinkage upon curing. UV15DC80-10 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. UV15DC80-10 has a service temperature range of -60°F to +350°F. Straight UV curing can be accomplished for thicknesses of 0.010” to 0.020” in seconds using UV light at 365 nm with 20-40 milliwatts/cm2 of energy. Faster cures can be achieved at higher energy outputs. Areas not cured because of shadowing can be cured at 80°C for 40-60 minutes. In addition, post curing at 125-150°C for 15-30 minutes can increase the Tg from 90°C achieved by straight UV curing to over 125°C. The 80°C secondary cure is a remarkable innovation.
