Sealant Bonds Quickly to Accelerate Assembly, Improve Reliability of LED Lamps and Luminaires

Dow Corning has released Dow Corning EA-2900 Sealant (white). One of the latest additions to the company’s broad and growing portfolio of advanced silicone solutions for LED lamp and luminaire applications,  EA-2900 Sealant rapidly forms bonds in as little as 10 minutes. This enables manufacturers to minimize delays to assembly or handling of parts, and ensures significantly faster production of LED modules, lamps and luminaires.

“As the demand for next-generation LED lamps and luminaires continues to accelerate and production volumes increase every day, OEMs are looking for new and innovative ways to push design boundaries, while optimizing manufacturing speed,” said Kaz Maruyama, global strategic marketing director, Lighting Solutions at Dow Corning. “Our new EA-2900 Sealant’s ultra-fast adhesion addresses these critical challenges by enabling significantly faster assembly and delivering the proven mechanical performance and reliable protection, after full cure, for which Dow Corning silicones are known.”

New Dow Corning EA-2900 Sealant rapidly forms workable bonds in as little as 10 minutes, allowing OEMs to handle and process parts with minimal delay to the LED manufacturing process. This advanced silicone material delivers improved unprimed adhesion to all conventional substrates and materials used in LED lighting assemblies, including aluminum, glass, polycarbonate, polymethylmethacrylate and Dow Corning molded silicone optics.

After full cure, EA-2900 Sealant offers greatly expanded design latitudes by enabling assembly of both optical and structural parts inside LED lamps and luminaires with a single material. In addition, it retains an Underwriters Laboratories (UL) 94-V1 Flammability rating, which contributes to the overall improved UL rating of completed LED fixtures in which EA-2900 Sealant is used.
