UR5640 is an optically clear polyurethane LED resin for potting or encapsulation. Suitable for aesthetic as well as protective application over the top of the luminaire UR5640 offers excellent protection from a variety of environments. Due to the aliphatic chemical nature of the resin chemistry, the cured UR5640 is naturally resistant to the yellowing effects of UV light, making it useful for a range of outdoor applications. UR5640 also shows excellent weather resistance, as well as chemical resistance against a range of chemicals. This enables this clear, though yet flexible resin to be used in a range of applications, both indoor or out.
