URETHAN 71/400, Polyurethane varnish 400ml

Urethan 71 Varnish is a high quality one-component polyurethane insulating and protective varnish for a wide range of applications in electronics and electrical engineering.

Urethan 71 Varnish forms a strong, durable, flexible, non-conductive film. The varnish provides durable protection in various conditions such as high humidity, salt fog. Urethan 71 protects against thermal and mechanical influences, is resistant to acids, alkalis and solvents, and is an anti-corrosion coating for all types of metals. Urethan 71 lacquer does not allow soldering through the lacquer layer.

Properties:
It has high dielectric properties.
Low loss factor and low dielectric constant.
Moisture resistant.
Antifungal.
A unique combination of strength, elasticity and high adhesion.
It has the advantage over two-component coatings due to its ease of application, while providing a high quality varnish coating.
