Desmophen® 800 is a solvent-free, highly branched polyester bearing hydroxyl resin of high viscosity, and is used in the formulation of two-component PU coatings. This product has a pour point of approx. +11°C, a viscosity at 23°C (70% in 1-methoxypropylacetate-2) of 850 ± 150 mPa·s, and an equivalent weight of approx. 200.
With Desmodur® L as the reaction partner, Desmophen® 800 yields hard films with good chemical resistance. These coatings are also characterized by high impact resistance, toughness and abrasion resistance. As a combination polyol with Desmophen® 1100, Desmophen® 800 can be used to formulate floor coatings with high abrasion resistance.
