Bayhydrol® UH XP 2592 is a Polyester-Polyurethane dispersion which dries by oxidation. It can be used as a binder in the formulation of aqueous air- and forced-drying, high-gloss coatings and primers with very good anti-corrosion properties. Mainly used for general industrial finishes. This product has an acid value of approx. 12, a viscosity at 23°C, (D=approx.40s-1) of approx. 300, a non-volatile content (1g / 1h / 125°C) of approx. 45, and a pH (1:4 in demineralised water) of approx. 7.2.
Bayhydrol® UH XP 2592 does not contain any cosolvents, no anti skinning agents and no driers and is therefore label-free. Coatings based on this resin show a quick drying and after drying a quite high hardness. After curing over night a very good water-resistance is achievable. High-gloss coatings, however, need a certain amount of suitable co-solvents and additional amine in the formulation. Bayhydrol® UH XP 2592 can be used as universal resin for high-gloss top coats, effect coats and - due to its excellent anti-corrosion properties – as raw material for primers and single coats.
