Material properties 2K-polyurethane varnish

2K-polyurethane varnish is a 2-component polyurethane cover coating for high-quality yacht and industrial appliance for exterior and interior use. In combination with aliphatic Polyisocyanate (PUR-hardener 72000) a yellowing free varnish with excellent resistance to weathering and corrosion and gloss retention is obtained.

Films have a high scratching and abrasion resistance, combined with a good solvent resistance. 2K-polyurethane varnish is applicable for coating of metals and plastics (GFK-components). 2K-polyurethane varnish has been proven since over 15 years for varnishing of wind turbine rotor blades.
