The conformal coatings of the series PETERS ELPEGUARD® SL 1301 ECO-FLZ are used to protect and insulate assembled pcbs so that they can fulfil higher requirements regarding reliability and service life. Owing to their very good resistance against moisture and condensation an excellent protection against corrosion (such as electro corrosion and migration) is possible. These conformal coatings are very environmentally friendly as they are absolutely free from aromatic solvents such as benzene, toluene, xylene and C9 aromatics. Furthermore, they contain neither free or volatile isocyanates nor free groups of isocyanates.
