| Aliphatic, fatty acid-modified, anionic polyurethane dispersion. Binder for the formulation of water-reducible coatings and sealers for wood and wood materials. Properties / Applications: The product was developed specifically for the formulation of one- and two-component wood coating systems. It is characterized by very good wet film transparency, high hardness and good black heel mark resistance. Post-curing of such coatings with Bayhydur® 305 or Bayhydur® 3100, for example, brings additional significant advantages and results in waterborne two-component coatings with even higher mechanical and chemical resistance. The mixing ratio of mill base to hardener solution is generally 10 : 1. The product is also suitable for use in a wide range of applications thanks to the combination of good application properties and good compatibility with cost-effective PAC dispersions. On account of the many potential co-reactants, compatibility testing should always be carried out. Information provided by Covestro |
