Bayhydrol® A 2470 is an aqueous hydroxyfunctional polyacrylic dispersion that has waterborne 2K-Polyurethane varnishes in combination with aliphatic Polyisocyanates. This product has a viscosity at 23°C, D=approx.40s-1 of 1,500 - 3,000, a non-volatile content (1g / 1h / 125°C / convection oven) of 44-47, and a pH (1:4 in demineralised water) value of 7-8.

Bayhydrol® A 2470 is a hydroxyfunctional polyacrylic dispersion which can be thinned with water to application viscosity. The viscosity of the product is largely governed by the pH. As the pH may decrease during storage, a decrease in viscosity is also to be expected. The viscosity can be restored to its original value by the addition of small amounts of an aqueous 10% solution of dimethyl ethanol amine.
