• ELPEGUARD® SL 1800 FLZ defying extreme frost

    SL-1800-FLZ__Stefan_Schröder2 (1)

    ELPEGUARD® SL 1800 FLZ impresses with its temperature flexibility, especially at low temperatures. The new product from the Peters’ research labs exceeds the industrial standard for cold-flexible acrylates by as much as 25 degrees. In other words, the conformal coating does not show any negative effects even under temperature shocks between 125 °C and -65 °C. “For the automotive and aviation sectors, it is now required to go beyond the lowest point of -40 °C into even more extreme frost layers. Our ELPEGUARD® product meets the demand claimed by these industries,” reports Stefan Schröder.

    The Global Product Manager Conformal Coatings refers to long- term tests performed in the Peters climate laboratory. In a test cabinet of the latest generation, i.e. the VT3 7012 S2 temperature shock system, electronic components and printed circuit boards undergo multiple rapid temperature changes in ranges between -80 °C and +220 °C.

    After the completion of thistest phase, graduate engineer Stefan Schröder emphasises that with SL 1800 FLZ, the further develop-ment of the Peters classic from the ELPEGUARD® 1307 conformal coating family can be considered successful. With ELPEGUARD® SL 1800 FLZ, the highly specialised research and development team in Kempen has once again come up with a forward-looking and practice-oriented solution. “The newcomer has even better end properties,” says Stefan Schröder.

    From the family of physically drying thin-film coatings, this modified acrylate is the measure of all things on the world market. Besides its high thermal shock resistance, the Peters ink also features a good wetting of silicone-contaminated surfaces when choosing the ELPEGUARD® conformal coatings of the SL 1801
    FLZ series.

    What makes the difference and the icing on the cake for the relevant industries for choosing ELPEGUARD®

    SL 1800 FLZ is, according to Stefan Schröder, its extreme resistance to even very low temperatures. In the au-tomotive industry, for example, one has to take into account that vehicles have to be reliably operational even in regions with permanent frost below -40 °C. In space, the circuit boards and their coatings are exposed to even lowersub-zero temperatures. As Stefan Schröder puts it, this kind of frost could be dangerous for conventional acrylics, as hairline cracks could lead to moisture penetration causing, in the worst case, failure of electronics. With ELPEGUARD® SL 1800 FLZ, there is no risk of den-
    drites forming even under difficult environmental conditions, provided the coating has been applied properly. Coating engineer

    Stefan Schröder: “And that is exactly why high-tech industries play it safe trusting the cold-flexible acrylate from Peters.

    Meets the best flame class What also speaks in favour of ELPEGUARD® SL 1800 FLZ is that it meets the best flame class according to UL. In other words, the single-component component coating has reached flame class UL 94 V-0, UL File No. E80315. UL is the registered trademark of Underwriters Laboratories Inc., of Northbrook, Illinois, the internationally recognised testing authority.

    “In addition, the ink is repairable – which is also what customer ask for nowadays”, reports Stefan Schröder. This allows saving costs in the long run. Repairable means that one can easily remove ELPEGUARD® with the thinner V 1800 and reapply it after repair. Stefan Schröder concludes: “The new product of the ELPEGUARD® SL 1800 FLZ series is excellently suited for pro- tecting and insulating assembled printed circuit boards, so that they can meet even higher requirements in terms of reliability and service life.” The ink also offers an outstanding protection against e-corrosion thanks to its high resistance to moisture and condensation water.

    By developing ELPEGUARD® SL 1800 FLZ, the Peters Group underlines its leading world market position in the field of high-tech coatings for electronics, from the manufacture of printed circuit boards and the protection of assemblies and electronic components up to integrated solutions for coating technology.
    According to Peters CEO Ralf Schwartz, high-tech coatings can be used in all kinds of industrial applications, and Peters is ready to deliver at any time.
