UV stable Polyurethane casting resin
UV stable Polyurethane is also very clear and has a medium viscosity. It has normal UV stable Polyurethane yellowing.
Intercol's polyurethanes are 100% resistant against yellowing, otherwise then with epoxies.
Transparent
polyurethanes can be used in a large number of outdoor en light applications. Both very small single LED applications and large scale projects (multi LEDs, large surfaces as within flooring) are possible. Because polyurethanes are very durable they can be used in hard wearing conditions such as vandalism resistant projects, roadmarks and traffic lights. Transparent polyurethanes offer new possibilities to for LED packaging and encapsulations (e.g. Protective encapsulants, lenses etc.).
non yellowing UV stable Polyurethane
all Epoxies are yellowing, some of them have UV blockers, but it is not a 100% solution and your product is not that clear anymore. Transparant Polyurethanes of Intercol are 100% clear and 100% UV-stable (non yellowing)
