Bayhydrol® A 2651 is an aqueous hydroxyfunctional polyacrylic secondary dispersion well suited for the formulation of high gloss and matt clear 2K polyurethane coatings, as well as pigmented coatings. This product has a pH (1:3 in demineralised water) value of 8-9, an acid value of 8-11.2, and a hydroxyl content solvent-free, calculated to approx. 3.
Bayhydrol® A 2651, combined with aliphatic polyisocyanates is well suited for the formulation of high gloss and matt clear 2K polyurethane coatings, as well as pigmented coatings. The product was developed in particular for the formulation of two-component wood coating systems. It is characterized by very good film transparency and high wood warmth. Crosslinking with Bayhydur® XP 2487/1 or XP 2655 yields coatings with very high chemical resistance.
