The top coat is a fast-curing, optically clear polyurethane encapsulant. It is UV stable (non yellowing), bubble resistant and offers excellent light transmission. The properties of this clear compound will be of interest in LED applications where environmental and mechanical protection are important such as outdoor lighting used for pathways, buildings and signage.
The base material is a bright, white, rigid polyurethane designed to offer mechanical protection with elevated thermal dissipation to avoid heat build up in the chip. It is easy to pour but is capable of gelling quickly.
- Thermal conductivity 0.8w/m/k
- Fast cure;takes 8 minutes to gel
Both products are available in bulk or twin pack.
