PU potting resin for LEDs gives diffused light effect
Provider of a variety of materials that offer environmental protection, extend service life and improve light performance, Techsil, supplies high performance LED chip packaging encapsulants, potting materials, thermal management solutions, and adhesives to bond lighting assemblies. Product chemistries include silicones, polyurethanes, epoxies, greases and pressure sensitive tapes.
Techsil's latest product is PU23955 – a new pearl PU resin used to encapsulate electronic devices containing LEDs. It cures to a tough, scratch resistant, opalescent material that diffuses transmitted light. The cured resin allows high transmission of diffused light but hides the underlying electronic components offering the electronics environmental and visual protection.
Techsil PU23955 is a 2-part flexible 55 shore D pourable potting polyurethane which cures to a translucent material that is stable in UV light. Once mixed, the system reacts at room temperature to produce a tough abrasion resistant material with good hydrolysis resistance. There are many applications for this product including assemblies, tracks, LED arrays, luminaires, up lights and lighting.
Key features:
- Opalescent in colour
- UV stability
- Non-toxic
- Water resistant
- Tough and abrasion resistant
- Available in a twin-pack which can be mixed by hand and free poured.
