Dielectric varnishPLASTIKbased on acrylic resins, it is most suitable for use in electronics and electrical engineering.
Forms an elastic, glossy transparent layer that resists acids, salts, mold, corrosive fumes, alcohols, thermal and mechanical influences, alkalis, moisture and other manifestations of an aggressive environment.
The coating remains effective over a wide temperature range from –70°C to+120°C.
Forms a stable film on metals, plastics, wood, glass.
Allows soldering through the protective layer when a PCB repair is required.

Protection of printed circuit boards, components, wires, cables, transformer and motor windings, etc.
Tips for applying varnish:
Elimination and prevention of current leakage, corona discharges, short circuits.
Corrosion protection of components exposed to adverse weather conditions.
Moisture protection for various materials such as cardboard, wood, leather.
Before application, the surface must be free of dirt, grease, etc. Apply the aerosol by spraying from a distance of approximately 30 cm, otherwise drips may form on the surface.
To ensure an even coating, the varnish must be applied in 2-3 layers with intermediate drying for 20-30 minutes.
A clogged nozzle of an aerosol can is washed with a solvent, acetone or turpentine.
