Bayhydrol® A 2290 is an aqueous hydroxyfunctional polyester polyacrylate dispersion that can be used in the formulation of two-component polyurethane topcoats and primers for plastics. This product has a non-volatile content (1g / 1h / 125°C, convection oven) of 43-47, a viscosity at 23°C, D=approx.40s-1 of 200-2,000, and an acid value of 11-13.

Bayhydrol® A 2290 is a polyester polyacrylate dispersion which has already been neutralized with dimethylethanolamine. It has good hydrolysis stability and can be thinned with water for application. It is preferably combined with Bayhydur® 3100, Bayhydrol® A 2290 can be used to formulate high gloss, solvent-resistant and tar-resistant top-coats. On many substrates, good adhesion with a good build can be achieved when the formulation is applied as a one-coat finish.
