Electrolube conformal coatings and resins

Electrolube is an expert in the formulation and application of conformal coatings designed to meet international approvals (including European and American military specifications). Its broad range of products comprises acrylics, silicones, polyurethanes and environmentally friendly VOC-free options.

The company’s 2K conformal coatings combine the two-part chemistry of encapsulation resins with the ease of application and process of a conformal coating. The coatings are solvent-free, fast curing and high performance, designed for application by selective coating. The 2K materials provide a solvent-free alternative to both single-part UV and silicone coating materials and are claimed to offer improved performance in harsh environments when compared to silicones.

Electrolube’s epoxy, polyurethane and silicone resin ranges have a wide range of potential applications, particularly in the LED market. The ER2224 epoxy provides high thermal conductivity and good thermal cycling performance, making it useful for LED lighting units where it helps to promote heat dissipation and prolong unit service life.

The tough UR5638 polyurethane resin provides high levels of protection while maintaining a clear, transparent finish. It exhibits high UV stability and good transmission of visible light, making it a suitable resin for white light LEDs. Its low exotherm during cure makes it particularly useful for LED applications involving the encapsulation of larger LED lighting units.
