Product description
Aliphatic, anionic polyurethane dispersion containing polycarbonate.Binder for the formulation of water-reducible coatings for plastic substrates and wood materials.
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).
