Optically Transparent Polymers for LED Encapsulation
Optically clear polymers allow light to pass through them without significant distortion. These materials are commonly used to protect LED circuitry from the harsh demands of outdoor environments, heat generation, liquid exposure, and hazardous environments. Our LED encapsulating materials are used to protect electronic circuitry in a variety of applications, including:
-
LED drivers
-
Power supplies
-
LED lamps with integrated drivers
-
Outdoor LED displays
-
Automotive lighting
-
Decorative and outdoor strip lighting
-
Pool & spa lighting
-
Emergency lighting & signaling

Optically Clear Compounds
Epic S7515 is a two-component optically clear aliphatic urethane compound. It has exceptional UV resistance. Low mixed viscosity and short gel time allow for easy air release and quick turnover of parts in high-volume production settings. It features a 1:2 volumetric mix ratio for easy adaptation to meter mix and dispensing machinery.
Perfect for high-volume production applications:
-
High strength + high stiffness yields strong, lightweight results
-
Low shrinkage allows for precision
-
High adhesion forms tight, reliable bonds
-
Thermal stability for tolerance of high temperatures
-
Tough chemical resistance to acids, solvents and bases
Epic D9980-01 is a rigid, two-component aliphatic urethane casting material. It is designed to be UV stable, optically clear, and display minimal color change and high gloss retention after 1,000 hours of accelerated weathering tests. This product is used in applications that operate up to 130C.
Epic S7524 is a 2-component transparent, UL 94 V-0-recognized polyurethane potting compound. It is unfilled and excellent for applications requiring low mixed viscosity for better flow into tight tolerance areas. It is an excellent choice for white goods applications, sensor potting, switches, and control modules.
