Bayhydrol® A 2646

Solubility / thinnability    The product is solublein water.

Properties / Applications    On account of itsoutstanding mechanical and 

                            The high reactivityenables 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 canalso be used for the formulation of 

                            high-grade low VOC coatings for use on substrates 

                            such as wood, metal, plastic, etc.
                            chemical resistance, theproduct 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 productcan also be combined with other water-

                            reducible binders. On account of the many potential

                            co-reactants, compatibility testing should always 

                            be carried out.
