RS PRO Transparent Potting Compound Polyurethane 250 g

RS PRO Polyurethane Resin

The RS PRO polyurethane resin is an optically clear compound, making it ideal for LED encapsulation. It is suitable for aesthetic as well as a protective application over the top of the luminaire. Due to the aliphatic chemical nature of the resin chemistry, the cured resin is naturally resistant to the yellowing effects of UV light. It 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 outdoor.
