Desmophen® VP LS 2328 is a solvent-free, low-viscosity, linear short-chain polyester polyol liquid, and is most often used as a binder for high-quality, high-solids or solvent-free, flexible two-component coatings. This product has an OH content of 7.95 ± 0.35%, an acid value of < 0.5mg KOH/g, and a vscosity at 23°C of 800 ± 50 mPa·s.
Desmophen® VP LS 2328 is used as the flexibilising component in two-component polyurethane coatings. Preferred polyol combinations are mixtures with e.g. Desmophen® VP LS 2249/1 as the hard component to achieve the desired flexibility. Desmophen® VP LS 2328 is suitable for the formulation of highly flexible polyurethane coatings. Combination with Desmophen® VP LS 2249/1 yields systems of medium flexibility.
