- Sealants
- maintenance-
- wood-
- industrial- and plastic coatings
- Advantages
- compatibility with 2K-PUR, polyesters, acrylates, flexible medium-oil or short-oil alkyd resins and other OH-group containing resins, dilution in aromatics and esters, light stability and outstanding weathering resistant in polyurethane paints, blends of Vestanat® HB 2640 with Vestanat® T 1890 in 2K-PUR paints improve drying performance, surface hardness, pot life and chemical resistance against enviromental impact
- Storage
- Vestanat® HB 2640/LV is moisture sensitive.It can be stored in unopened containers for at least 6 months at room temperature without loss of quality
- Handling
- The basic reactivity of Vestanat® HB 2640/LV is lower compared to aromatic- and higher compared to cycloaliphatic polyisocyanate. If necessary zinc octoate, tin- or bismuth-catalysts are recommended as a urethane catalyst.
