ELPEGUARD® UV Twin-Cure® DSL 1707 NV-FLZ combines the advantages of very fast UV curing with the outstanding final properties of a silicone. « 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 refers to long-term tests carried out in the climate laboratory of the headquarters located in the Lower Rhine region where the Peters Research R&D team is based.
As the only full range supplier of coatings materials for the electronics industry worldwide, Peters understood the need for a high performance, high speed conformal coating to meet the demanding requirements of today’s manufacturers. Peters turned to their partner Novagard Solutions, Inc., the high-tech company from Cleveland, Ohio to develop and manufacture this innovative silicone material. The resulting product reflects the commitment to quality of two established brands: Peters and Novagard. ELPGUARD® UV Twin-Cure® DSL 1707 NV-FLZ is a testament to the growing cooperation with Novagard in the field of silicone-based coating materials for printed circuit boards.
Usable over the entire surface of assembled PCBs
« Our ELPEGUARD® UV Twin-Cure® DSL 1707 NV-FLZ can also be sprayed and is suitable for coating large areas, » says Stefan Schröder when describing the newcomer. According to the graduate engineer, assembled PCBs can therefore be coated thinly and yet durably using the spray process. This is a new feature of this product range. The already familiar ELPEGUARD® UV Twin-Cure® DSL 1707 FLZ coating system can only be processed using a dispenser.
Sustainability is ensured by the fact that the thick-film coating does not release any solvent emissions when processed. In terms of costs, the dual curing mechanism of the Twin-Cure® systems shortens process times, thus saving time. What is sustainable is that the coating can be repaired easily. Stefan Schröder: « This ensures that it can be recycled. »
The new silicone conformal coating is particularly suitable for high-temperature applications. Stefan Schröder: « The silicone remains permanently elastic and also allows higher selective layer thicknesses without compromising on quality and
properties. »
Durable, robust, temperature-resistant
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.
« Ensuring climatic resistance and flammability ratings for our customers’ specifications were key goals when developing this new product,” says Stefan Schröder. It was certified UL 746E after a series of tests proved. The coating withstands sudden electric shocks and retains its dielectric integrity, resulting in an optimum protection of the coated assembly.
By the development of the thick-film coating ELPEGUARD® UV Twin-Cure® DSL 1707 NV-FLZ, 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 dedication. Together, we have provided the electronics manufacturing industry with a great product, » says Peters CEO Ralf Schwartz.
