| Aliphatic, anionic polyurethane dispersion containing polycarbonate; solvent-free. Binder for the formulation of water-reducible coatings for plastic substrates and wood materials. Properties / Applications: The product was designed specifically for the coating of plastic substrates. In addition the use in the formulation of PVC floor coatings, the binder exhibits a high grade property profile on a variety of substrates. Filler and topcoat applications (one and two-component) are also plausible. Other possibilities are wood and furniture applications. Bayhydrol UH 2606 yields coatings with good leveling, chemical and weather stabilities. They are also characterized by a tough but flexible property profile. Very good combinations are possible with polyester, polyurethane and acrylic dispersions. These must be checked on a case-by-case basis. Combinations with waterborne UV systems are also possible. Resistances can also be improved by post-curing with e.g. Bayhydur®. The mixing ratio of mill base to hardener is generally 10 : 1. Bayhydrol UH 2606 requires coalescing agents for film formation. Good results have been achieved with mixtures of butyl glycol/butyl diglycol/Dowanol TPnB (0.6 : 0.6 : 3.8). Information provided by Covestro |
