Description

PVB 60 varnish 50 ml with brush is a fast-drying, transparent protective coating for printed circuit boards and electronic components. It forms a highly durable insulating film that protects against moisture, corrosion and contaminants, while still allowing soldering through the coating.

Benefits and unique features

  • Solder-through capability – faster servicing without stripping the coating
  • Fast drying: approx. 40–45 minutes
  • High clarity – easy visual inspection of PCBs
  • Effective barrier against moisture and corrosion
  • High dielectric strength and very high resistivity
  • Convenient 50 ml bottle with brush; coverage approx. 0.25 m²

Properties and applications

  • Dielectric strength >89 kV/mm: insulating parts and preventing stray currents
  • Volume resistivity >1.0×1014 Ω·m, surface >1.1×1014 Ω: protection of precision electronics
  • Operating range −50 to +150 °C, application −40 to +60 °C: reliability in harsh conditions
  • Transparent film: protection of PCBs, transformers, motor windings, cables and connector housings
  • Application methods: brush (included), dip or spray
  • Thinning: may be diluted with a suitable PVB thinner to adjust spray viscosity
