PVB 60 Varnish, 50 ml, brush-top – transparent PCB protective coating, fast-drying, solder-through, high insulation
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
