Polyurethane varnish provides permanent protection for substrates. It may be one-part or two-part. It is applied to a wide variety of substrates and protects them from aggressive external agents (UV, chemicals, scratches, moisture, etc.).
Some of our polyurethane varnishes can provide F-class thermal protection (-20°C to +150°C). In certain applications this varnish may also enhance mechanical properties and provide dielectric strength.
