Bayhydrol? A 2646
Solubility / thinnability    The product is soluble in water.
Properties / Applications    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.
                             The binder can also be used for the formulation of 
                             high-grade low VOC coatings for use on substrates 
                             such as wood, metal, plastic, etc.
                             The product can also be combined with other water-
                             reducible binders. On account of the many potential
                             co-reactants, compatibility testing should always 
                             be carried out.
                             The high reactivity enables short drying times, 
                             which contribute to enhanced productivity.
                             The viscosity of the product is largely governed by
                             the pH. As the pH may decrease during storage, a 
                             decrease in viscosity is also to be expected. The
                             viscosity can be restored to its original value by
                             the addition of small amounts of triethanol amine.
                             Dowanol? PnB and triethanolamine are OH-functional
                             cosolvents/amines that react with isocyanates. They
                             are therefore reactive thinners and not 
                             VOC-relevant pursuant to the Decopaint Directive 
                              2004-42-EC.

Storage                      - Storage in original sealed Bayer MaterialScience 
                              containers.
                             - Recommended storage temperature: > 0 - 30 °C.
                             - Protect from frost, heat and foreign material.
                               General information: The product is sensitive to
                               frost. Prolonged freezing can damage the product
                           irreversibly. Prolonged storage at higher temperatures
                           may result in a decrease of viscosity and/or an 
                           increase of average particle size, possibly resulting 
                           in sedimentation or coagulation.
                           The viscosity of the product is largely governed by 
                           the pH. As the pH may decrease during storage, a 
                           decrease in viscosity is also to be expected. The
                           viscosity can be adjusted to its original value by 
                           the addition of small amounts of an aqueous 10 % 
                           solution of Triethanolamine.
                           Contamination with certain bacteria, fungi or algae 
                           may render the product unusable.
