The Elpeguard UV Twin-Cure DSL 1707 NV-FLZ thick-film varnish from Peters combines the advantages of very fast UV curing with the outstanding final properties of a silicone. The new development is a high-performance and fast sprayable protective lacquer for coating printed circuit boards.

"The silicone structure of the thick-film coating ensures a high long-term temperature resistance of approx. 180°C. It is characterized by almost constant elasticity down to a temperature of -40°C," reports Stefan Schröder. The Global Product Manager Conformal Coating at Peters refers to long-term tests in the climate laboratory at the Peters Research R&D team's headquarters in the Lower Rhine region. As the only full-range supplier of coating materials for the electronics industry, Peters recognized the need for a high-performance and fast protective coating that meets the high requirements of manufacturers. To develop and manufacture this innovative silicone material, Peters turned to partner Novagard Solutions Inc, a high-tech company based in Cleveland, Ohio. The resulting product reflects the quality commitment of two established brands: Peters and Novagard. The Elpeguard UV Twin-Cure DSL 1707 NV-FLZ is a statement in the growing cooperation with Novagard in the field of silicone-based coating materials for assembled printed circuit boards: "Our Elpeguard UV Twin-Cure DSL 1707 NV-FLZ can also be sprayed and is suitable for flat coating," says Stefan Schröder, describing the newcomer. This means that assembled PCBs can be coated thinly and yet durably using the spray process. This is new in this product range. The already familiar Elpeguard UV Twin-Cure DSL 1707 FLZ coating system can only be applied using a dispenser. Sustainability is ensured by the fact that the thick-film coating does not release any solvent emissions during processing. In terms of costs, the dual curing mechanism of the Twin-Cure systems results in short process times, saving time. What is sustainable is that the paint can be easily repaired. Stefan Schröder: "This ensures that it can be recycled." The new silicone protective coating is particularly suitable for high-temperature applications. Stefan Schröder: "The silicone remains permanently elastic and also allows selectively higher layer thicknesses without compromising on quality and properties."

The bottom line is that Elpeguard UV Twin-Cure DSL 1707 NV-FLZ combines three advantages in one coating system: chemical resistance, physical robustness and, as a highlight, permanent temperature resistance. Climatic resistance and flame resistance in accordance with our customers' specifications were the most important requirements when developing this new product," says Stefan Schröder. The product was certified to UL 746E after a series of tests. The coating withstands sudden current surges and maintains its dielectric integrity, resulting in optimum protection of the coated assembly. With the development of the Elpeguard UV Twin-Cure DSL 1707 NV-FLZ thick-film coating, the Peters Group in partnership with Novagard Solutions Inc. is underlining its leading global market position in the field of high-tech coatings for electronics in the manufacture of printed circuit boards and the protection of assemblies and electronic components through to integrated solutions for coating technology. "This now also applies to silicone-based coating materials from our company. We would like to thank Novagard for their innovation and commitment. Together we have provided the electronics manufacturing industry with a great product," says Peters Managing Director Ralf Schwartz.
