Product Description

UR5634 optically clear polyurethane LED potting compound is a two-part, semi-rigid polyurethane resin. Formulated with a carefully selected blend of components specifically to be optically clear, making it ideal for LED encapsulation or potting. Its clarity makes it an excellent choice for use in both decorative and protective applications in the LED luminaires industry.

It exhibits superb weather resistance, as well as good resistance to acids and alkalis making it suitable for a wide range of environments and an extremely durable potting and encapsulation compound for use in a wide range of applications.

It is also strongly resistant to yellowing when exposed to UV light making it especially useful as an outdoor LED encapsulant or for use in other applications where it may be exposed to direct sunlight.

UR5634 has a simple mix ratio of 1:1 for ease of processing with a low viscosity aiding application.
