Varnish PVB 16 is a universal varnish for printed circuit boards. A quick-drying transparent PVB coat with good isolation properties. Protects printed circuit boards and other elements operating in unfavourable weather conditions from corrosion. The coating protects printed circuit boards against the creation of stray currents and short circuits. Creates a protective and insulating layer that protects against weather influences such as moisture, oxidation, dusts, chemical contaminations; Adheres well to metal, plastic and wood surfaces; Creates a coating resistant to diluted acids, alkalis, and atmospheric agents; It is possible to solder through the varnish layer; Prevents sparks and corona discharge; Limits ground failures between paths; It does not change the transparency and elasticity even after a long time. Operating temperature -50°C - 150°C.
