Novagard’s Next Generation UV/Dual Cure Silicone Conformal Coating Platform is a fundamental improvement that is quickly becoming a competitive advantage for our customers. Solvent free, it cures completely within 24 hours without the use of high temperature ovens. Because our UV cure dries to a tack-free surface in seconds, racking can be eliminated and production time slashed.
The conformal coatings that provide the necessary protective shield and insulation for Printed Circuit Boards (PCBs) and other electronic assemblies aren’t usually in the spotlight. And while the properties of silicone are well known, we admit it’s rarely labeled an “exciting technological breakthrough”. But when you put enough brainpower into problems, sometimes a solution deserves that label.
Drawing on years of silicone expertise, our R&D lab combined a UV cure that dries tack free in seconds with a secondary moisture cure that eliminates unreacted coating in shadow areas. “Listening to our customers drove our need to innovate conformal coatings,” explains Jason Clark, Vice President, Electronics and EV at Novagard. “The rapid UV dual cure our team developed builds instant adhesion without the need for hazardous solvents. It is an order-of-magnitude change from current market offerings, greatly increasing our customer’s speed for final assembly and product shipment.”

Novagard’s 800-505 UV/Dual Cure Silicone Conformal Coating dries tack free in seconds. This allows components to move to the next step of assembly in less than 5 seconds, enabling manufacturers to skip the oven cure and eliminate racking. In effect, the parts finish curing as they move to the next stage of manufacturing. Customers can literally cut hours, and sometimes days, off of their manufacturing process.
The UV cure process has effectively proven superior to all oven methods, and as cure times have dropped from hours to seconds, it’s becoming the standard for PCBs and other electronic assemblies in the automotive, medical, marine, and defense industries. Especially in large curing or high throughput processes, better coverage and faster processing time is critical. By combining a UV primary cure with a secondary alkoxy cure, the resultant UV/Dual cure system provides manufacturers with a dramatic decrease in the total cost of ownership (TCO). 800-505 UV/Dual Cure Silicone Conformal Coating eliminates the need for high energy ovens, enclosures, and racking – reducing dedicated floor space and cutting energy costs.
A faster, more reliable cure, 800-505 UV/Dual Cure Silicone Conformal Coating is an attractive alternative to solvent-based solutions. Silicone are low VOC and non-flammable, enabling engineers to provide a less hazardous, environmentally friendly work environment.
With 800-505, there’s no compromise on coverage. Due to its low viscosity, 800-505 is easily applied using standard PCB spray coating equipment. After the initial UV cure, the secondary, ambient cure ensures no unreacted coating remains in shadow areas. Broader viscosity ranges offer better coverage, even in small shadow areas – and the alkoxy cure means even components with deeper shadow areas can move on to the next step immediately.
As with most silicones, 800-505 has excellent dielectric properties and offers better protection from corrosion and other harsh environmental elements than other coating technologies such as acrylics and urethanes. Our fast-acting cure minimizes potential damage of delicate components during the production process.
