Master Bond UV15DC80Med is a special dual cure epoxy based system that offers a primary cure using UV light along with a secondary heat curing mechanism. This extraordinary compound also meets USP Class VI specifications and passes ISO 10993-5 testing. UV15DC80Med allows for curing areas on parts that do not allow UV light curing because of “shadowing” issues. It is important to note that the heat curing portion of this system can be initiated at the relatively lower temperature of 80°C. This kind of UV system is highly desirable because it allows for rapid fixturing with completion of the cure accomplished by adding heat. As alluded to above, a secondary cure at 80°C is not very common. This curing temperature is desirable because many plastics are sensitive to elevated temperatures above that point. One innovative use of a dual cure UV is to fixture two optically opaque substrates, such as metals, using UV light exposure from a side angle and then completing the cure with heat.
UV15DC80Med is a moderate viscosity system. The UV portion of the curing mechanism is cationic in nature. This type of curing system generally imparts lower shrinkage upon curing and is not susceptible to oxygen inhibition. UV15DC80Med has very good temperature resistance along with the capability of withstanding many chemicals including liquid sterilants, radiation and even steam (in the form of autoclaving). As one might expect, it is a first rate electrical insulator. UV15DC80Med has very good adhesion to metals, glass, ceramics and many plastics. The service temperature range is -80°F to +400°F.
UV15DC80Med will fully cure with UV light in 5-30 seconds depending upon the intensity of the light, the duration of the exposure and the distance of the light source from the material being cured. Areas not cured because of shadowing, should be heated at 80°C for 2-3 hours. Post curing for an additional 2-4 hours will help optimize properties. And if possible, more curing at 125°C for 1-2 hours, will further enhance product properties.
In summary, UV15DC80Med is a one part, fast curing, easy to use system with compelling product properties upon curing and that also meet biocompatibility requirements.
