RELEASE: Novagard Achieves UL 746E Certification for Two Conformal Coatings

CLEVELAND, Aug. 17, 2023 /PRNewswire/ -- Novagard, a woman-owned innovator and manufacturer of silicone sealants, coatings, lubricants and foams, announced that it has received UL 746E certification for two of its conformal coatings.

A conformal coating is a thin polymeric film layer applied to printed circuit boards (PCBs) to protect the circuitry from moisture, dust, and other contaminants. PCBs are used in a wide spectrum of industries, including electronics, automotive and electric vehicle electronics, aerospace, renewable energy, LED lighting, medical devices, and telecommunications equipment.

"We are delighted that 800-505FC UV Alkoxy Dual Cure Sprayable Silicone and 500-210 General Purpose Conformal Coating passed the rigorous testing required to achieve UL 746E certification," said Robert Duan, Ph.D., Novagard vice president of R&D. "At Novagard, we are committed to offering products that meet the highest standards our customers demand."

UL 746E certification is earned after a product passes a series of tests to assess whether a conformal coating can withstand sudden electrical surges and maintain its dielectric integrity. These are performed in succession and include: transient voltage test, dielectric withstand test, and dielectric breakdown. A vertical combustion flammability test was also performed as part of the UL 746E certification, and both coatings have a V1 rating.

800-505FC UV Alkoxy Dual Cure Sprayable Silicone cures in 3-5 seconds after exposure to UV light. It has a secondary neutral alkoxy moisturizing cure for shadow areas that starts immediately and develops full adhesion in hours.

500-210 General Purpose Conformal Coating is a clear, moisture-cured sprayable silicone that offers simple “dispense and forget” processing and tack-free performance in as little as 10 minutes.

With the miniaturization and electrification of everything, silicones play a vital role in today's manufacturing process. Novagard's moisture-cure and UV/dual-cure silicones cure tack-free in a fraction of the time required by traditional conformal coatings. After the initial UV cure, secondary curing ensures that no unreacted coating remains in the shadow areas.

Novagard electronic grade silicones offer superior performance in harsh and demanding environments. They combine greater flexibility and resistance to high temperatures, offering more versatility in the design and assembly process. Novagard silicones seal, bond, coat, package and encapsulate to protect sensitive components and modules, enhancing and enabling its customers' technological innovations. These high performance materials contain NO added solvents (no isocyanates, benzene, toluene, ethylbenzene or xylene) and are PFAS free.

Novagard will be demonstrating its UL 746E certified conformal coatings in booth 1845 at The Battery Show in Novi, MI (September 12-14).
