PVB 16 Varnish

PVB 16 varnish is a high-quality insulating agent based on polyvinyl butyral, designed for long-term protection of printed circuit boards against adverse external factors. It provides a reliable foundation for electronic projects, forming a flexible and transparent layer that effectively protects components against corrosion and leakage currents.

Key Features and Specifications of PVB 16 Varnish

Proper protection of copper layers and solder points determines the reliability of devices operating in high-humidity conditions. The technical parameters that ensure the effectiveness of this protection are:

• Coating type: Fast-drying insulating varnish with low viscosity, forming a coating resistant to salt and diluted acids.
• Serviceability: The product allows soldering through the varnish layer, significantly facilitating repair work without the need for chemical removal.
• Operating temperature range: The coating maintains its protective properties over a wide temperature range from -40°C to +60°C.
• Form and capacity: Supplied as a 400 ml aerosol, allowing precise and even coverage of complex surfaces.

PVB 16 varnish is valued by both hobbyists and professionals, providing a solid foundation for many applications requiring reliable electrical insulation.

Typical Applications of PVB 16 Varnish

Thanks to its versatility and fast drying, this product is widely used in professional production and servicing of electronic equipment. It is most commonly applied for:

• protecting printed circuit boards (PCBs) in devices operating outdoors or under challenging workshop conditions;
• insulating wires and cables to prevent short circuits in high-signal-density areas;
• protecting transformers and electric motors from moisture and adverse atmospheric effects;
• maintenance of connections in the automotive and power industries, where resistance to vibration and chemical deposits is required;
• creating protective layers on antennas and communication systems exposed to direct rain.

With its proven formula and ease of application, this varnish is used in professional laboratories and on assembly lines for precision electronics.
