Bayhydrol A 2646

Solubility / thinnability    The product is soluble in water.

Properties / Applications    On account of its outstanding mechanical and 

                             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.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.
                             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 product can also be combined with other water-

                             reducible binders. On account of the many potential

              &nbp;              co-reactants, compatibility testing should always 

                             be carried out.
