It is used as a coreactant for Bayhydur® and Desmodur® polyisocyanates in the formulation of aqueous two-component polyurethane systems for various applications by brush, roller or spray. This product has a viscosity at 23°C, (D = approx. 165 s-1) of 200 ± 100, a non-volatile content (1g, 1h, 125°C) of 42 ± 2, and a pH (10% in demineralized water) value of 7.1 ± 0.7. Bayhydrol® A 242 is a water-thinnable hydroxyfunctional polyacrylic resin with emulsifying properties. It is neutralised with ammonia. Given the special composition of this product, both hydrophilic polyisocyanates, e.g. Bayhydur® 3100, and hydrophobic grades, such as Desmodur® N 3400 and others, are suitable co-reactants. The resultant water-thinnable two-component system cures to yield a polyurethane film with good general properties, and only a small-scale polyurea reaction takes place. 收起 | |

This product has a non-volatile content (1g / 1h / 125°C / convection oven) of 48-51, a viscosity at 23°C, D=approx.40s-1 of 1,000 - 3,500, and a pH (1:4 in demineralised water) of 7-8. On account of its outstanding mechanical and chemical resistance, the product is particularly suitable for the formulation of hard, high-gloss sealers for mineral substrates and reactive resins (EP, PUR). Furthermore, excellent accentuation of the grain of the substrate (e.g. colored coatings) is achieved. 收起 | |
