PUS433 Solvent-free Polyurethane Topcoat is a polyurethane coating used as a topcoat. High-build type, achieving a film thickness of 100–200 µm in a single coat; the film offers excellent weather resistance and colour and gloss retention and is widely used as deck paint and hull paint. A two-component solvent-free polyurethane topcoat, high gloss or semi-gloss, in various colours. Parameters on this page: volume solids 100%, dry film thickness 100–200 µm, theoretical spreading rate 5.33 m²/kg.

Before applying this product, all cracks, joints, protrusions and depressions in the concrete floor shall be properly treated, a sealer applied and conductive copper foil grounding laid; it may also be applied over conductive coatings (such as conductive filler or conductive intermediate coat), keeping the base flat, clean and dry. The product may also be applied directly to conductive substrates such as metal and antistatic terrazzo. At application temperatures of 20 °C and above, the summer grade is recommended; at 0–20 °C, the winter grade; below 5 °C, curing is slow. Mix only the amount needed and use within the pot life, stirring thoroughly, to avoid waste from gelling. The coating is walkable 24 hours after application and shall be put into service only after full cure. The film appearance depends on ambient temperature and humidity; a good appearance is obtained above 10 °C and below 85% relative humidity.
