W´Pol 6756 is a saturated, hydroxy functional polyester resin for the manufacture of solvent based "ultra high solids" 2 component PUR systems.
In combination with aliphatic polyisocyanates W´Pol 6756 is used in high quality air- and forced-drying 2 pack-"ultra high solids" lacquers for industrial and car repair coatings and shows good mechanical properties as well as chemical and outdoor resistance.
The special dilutibility enables the formulation of 2 pack topcoats with low VOC (calculated value of approx. 400 g/l in a white testing formulation at a viscosity of 21 s at 20 °C in a DIN 4 mm-cup) and at the same time good drying and high hardness.
In corresponding lacquer formulations (with compatible "low or medium solids"- acrylic polyols) with W´Pol 6756 the non volatile content of the lacquer can be increased as well as the chemical and outdoor resistance be improved.
