Varnishing circuit boards with a protective varnish is a fast and economical method for large production runs. It is also a good method if casting becomes too expensive or too heavy.
✔ A good circuit board varnish must have low viscosity, good spreading and perfect adhesion to the substrate. It meets our silicone-based varnishes.
Circuit board varnish made of silicone has also been shown in tests to provide better protection of circuit boards against, among other things, corrosion caused by condensation than conventional varnishes, above all in an environment rich in salt water. For products that will be left outdoors, silicone is probably the best option for climate protection.
Depending on the size of series to be produced and the speed at which production must be maintained, we offer several different protective varnishes and a first-class range of silicone products, all of which are free from
