Universal varnish based on polyvinyl butyral for protection of printed circuit boards, windings of transformers and electric motors.
Fast drying clear PVB coating with good insulating properties. Protects against corrosion of printed circuit boards and other elements operating in adverse atmospheric conditions.
The coating protects printed circuit boards from the formation of stray currents and short circuits.
Highly fluid, penetrates well into porous structures, fills microcracks.
forms a protective and insulating layer that protects against atmospheric influences such as: moisture, oxidation, dust, chemical pollution
Adheres well to metal, plastic and wood surfaces
-
forms a layer resistant to diluted acids, alkalis and atmospheric factors
-
soldering through a layer of varnish is possible
-
prevents sparking and corona discharge
-
limits gaps between tracks
-
does not change transparency and elasticity even after a long period after application
-
application temperature range: -40°C to +60°C
-
operating temperature -50°C + 150°C
-
flash point - 380°C
Convenient packaging for small repairs - a bottle with a brush.
Application:
It isolates and protects electronic boards, cables and wires, high voltage transformers, electric motor windings.
It is used in the automotive industry to protect auto electronics from adverse environmental influences.
Varnish recommendations:
Before application, the surface must be free of dirt, grease, etc. Apply by brush, dip or spray gun. Spray applied by spraying from a distance of approximately 30 cm, otherwise streaks may form on the surface.
To ensure a uniform coating, the varnish must be applied in 2-3 layers with intermediate drying for 20-30 minutes.
Reference Information:
Polyvinyl Butyral (or PVB) is a resin primarily used for applications requiring strong bonding, optical clarity, adhesion to many surfaces, strength and flexibility. It is obtained from polyvinyl alcohol by reaction with butyric aldehyde. The main application is laminated safety glass for car windshields. Trade names for PVB films include KB PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol and EVERLAM. PVB is also available as a 3D printer filament, which is stronger and more heat resistant than polylactic acid (PLA).
PVB resins (provided by the manufacturer in powder or granular form) are also used in a variety of applications including technical ceramic (temporary) adhesives, inks, dye transfer paints, paints and coatings (including primary primers), reflective sheet adhesives, and adhesives for magnetic media.
PVB resin is especially useful when bonding to metals, ceramics and other inorganic materials.
