Light Emitting Diode (LED) Potting Applications and LED Encapsulants

LED EncapsulationEpoxy Resin and Polyurethane Compounds for LEDs

Recent research shows the demand for LED encapsulants is expected to double in the next few years, with packaged LED lighting dominating this demand. Epic Resins offers the highest quality LED encapsulation for virtually any industry and application. LED encapsulants are engineered to prevent fragile wire bonds from breaking, keeping LED lights in tact and damage free. Encapsulating your LED lights protects against moisture, thermal shock, vibration, extreme temperatures, and other potentially damaging environments. The LED encapsulation process includes  pouring liquid epoxy into the LED chamber and inserting the bracket to create the desired shape. The mold is then set in the oven until hardened. Our epoxy manufacturers have exceeded industry expectations for decades in terms of quality, cost, and dependability. Utilizing the best LED encapsulation technologies and decades of industry training, we provide unbeatable service for each customer we serve. Our state of the art epoxy manufacturing equipment ensures LED encapsulation is performed correctly the first time, producing exceptional results. When you’re seeking cost-effective LED encapsulation  you can depend on, turn to  none other than Epic Resins.

LED Encapsulation Improving a Variety of Applications

Light Emitting Diode (LED) potting applications are extremely varied in terms of hardness, pot life, thermal abilities, temperature tolerance, viscosity, and more. Epic Resins manufactures a product line of epoxy resin and polyurethane potting and encapsulating compounds that meet the needs of LED product manufacturers when LED encapsulation is required. Our LED epoxy and polyurethane potting compounds are used in applications ranging from automotive lights and LED signs to LED indicators that are incorporated into other products. Combining polyurethane compounds in the LED encapsulation n process prevents mechanical and moisture damage, extending the life of LED lights. For those seeking extreme temperature and thermal resistance, we recommend our epoxy LED encapsulation.

Other common LED encapsulation applications include:

  • Theater lighting
  • Architectural lighting

Polyurethane LED potting compound S7144

From extremely thermally conductive epoxy LED potting compounds to flexible polyurethane LED potting compounds that will seal out moisture and contaminants over a large temperature range, Epic Resins can help to select the proper material for your LED encapsulation application. 

The Hammer Testing Findings for Solid-State Lighting Luminaires suggests the reliability of LED lighting can be improved with better driver design. Selecting the appropriate potting compound is imperative in controlling two common failures in SSL Luminaires: board-level corrosion and solder joint fatigue in the driver circuit. These findings are discussed in detail here.
