The new UR5641 resin is halogen-free and based on aliphatic polyurethane chemistry, without solid fillers and using a specific combination of PIN flame retardants. It is resistant to yellowing by UV light and so useable in both interior and exterior applications. It is flexible and resistant to weathering, acids and alkalis, water and mould growth, at operating temperatures -40 to +120°C. It can be used in hazardous atmospheres, ATEX zones and emergency lighting.
