UR5634

Polyurethane Resin

UR5634 is a two-part, semi-rigid optically clear polyurethane resin ideal for use in protective applications. Due

to a carefully selected blend of components an extremely durable, low viscosity system is achieved which can

be used for a wide variety of applications.

 Water white transparency; ideal for LED applications

 1:1 by volume mix ratio; aids ease of processing

 Does not contain IPDI; low hazard material

 High resistance to weather/UV, acids and alkalis, water and mould growth; suitable for a range of environments

Bulk Mixing When mixing, care must be taken to avoid the introduction of excessive amounts of air. Automatic mixing equipment is available which will not only mix both the resin and hardener accurately in the correct ratio but do this without introducing air. Containers of Part A (Resin) and Part B (Hardener) should be kept sealed at all times when not in use to prevent the ingress of moisture. Bulk material must be thoroughly mixed before use.
