LED Encapsulation Solutions for Submersible & Chlorinated Environments

LEDs used in pool and spa systems face continuous exposure to water, fluctuating temperatures and corrosive chemicals like chlorine and bromine. Encapsulation materials must prevent moisture intrusion while maintaining optical clarity and mechanical integrity over time. Epic Resins formulates epoxies and polyurethanes with excellent hydrolytic stability, strong substrate adhesion and the flexibility to accommodate thermal expansion for sealed lighting components in submerged or wet locations.

Reliable Light Output in Demanding Water Settings

Pool and spa lighting must remain bright, stable and visually clear despite constant exposure to moisture and thermal cycling. Epic Resins’ encapsulation materials help preserve LED color consistency and brightness while protecting internal components from corrosion and material breakdown. With low shrinkage, strong bond strength and long-term clarity, our epoxy and polyurethane compounds support safe and attractive underwater lighting in residential and commercial environments.

Polyurethane & Epoxy Systems for Wet-Use LED Applications

Epic Resins offers a variety of encapsulants designed for LED modules in submerged or wet-location environments. Low-viscosity formulations allow complete coverage in tight assemblies, while UV-stable polyurethanes help maintain clarity over time. Flexible materials absorb thermal stress without cracking or delaminating for applications with frequent temperature swings. Each system can be custom-formulated to support performance goals in freshwater and chemically treated water settings.
