Novagard, a manufacturer of silicone sealants, coatings, lubricants and foams announces that they received UL 746E certification on two of their conformal coatings. A conformal coating is a layer of thin polymeric film that is applied to Printed Circuit Boards (PCBs) to protect circuits from moisture, dust and other contaminants.
It’s called a conformal coating because it conforms to the contours of the PCB. PCBs are used in a broad spectrum of industries, including electronics, automotive & EV electronics, aerospace, renewable energy, LED lighting, medical devices and telecommunications equipment.
Products Meeting with Highest Standards
“
We’re extremely pleased to have our both 800-505FC UV Alkoxy Dual Cure Sprayable Silicone and 500-210 General Purpose Conformal Coating pass the rigorous testing required to achieve UL 746E certification,” said Robert Duan, Ph.D., Novagard’s vice president of R&D. “
At Novagard, we are committed to delivering products that meet the highest standards our customers demand.”
UL 746E certification is obtained after the product passes a series of tests meant to evaluate whether a conformal coating can withstand sudden electrical surges and maintain its dielectric integrity. These tests are done in succession and include voltage transient testing, dielectric withstand testing and dielectric breakdown.
In addition to the electrical testing, there is also a vertical burn flammability test conducted as part of the UL 746E certification. Both of these Novagard conformal coatings are rated V1 for flammability.
800-505FC UV Alkoxy Dual Cure Sprayable Silicone offers manufacturers a coating that cures in 3 – 5 seconds upon exposure to ultraviolet (UV) light. It has a secondary, neutral alkoxy moisture cure for shadow areas that begins 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.
Offers Superior Performance in Harsh Environments
With the miniaturization and electrification of everything, silicone plays a vital role in the manufacturing process. The next generation of Novagard moisture cure and UV/dual cure silicones cure tack free in a fraction of the time needed for traditional conformal coatings. After the initial UV cure, the secondary cure ensures no unreacted coating remains in shadow areas.
Novagard electronics grade alkoxy silicones offer superior performance in harsh and demanding environments. They combine increased flexibility and high temperature resistance, offering more versatility in the design and assembly process. Novagard silicones are PFAS free, making them a safer option for their customers and the planet.
Novagard silicones reliably seal, bond, coat, gasket and encapsulate to protect sensitive components and modules, enhancing and enabling their customers’ technological innovations. These high-performance materials contain no added solvents - no isocyanates, benzene, toluene, ethylbenzene or xylene.
