It can be used in combination with amino resins or blocked polyisocyanates for waterborne, one-component, industrial baking coatings. This product has an acid value of 10 ± 3, a viscosity at 23°C, (D = approx. 40 s-1) of 950 ± 550, and a non-volatile content (1g / 1h / 125°C/ convection oven) of 45 ± 2. Bayhydrol® A 145 has good pigment wetting properties and high shear stability. Bead mills have proved suitable as grinding equipment. Only pigments and extenders with a minimal water-soluble content should be used. Bayhydrol® A 145 combined with aliphatic polyisocyanates yields high-gloss topcoats which can be dried at room temperature or force-dried, e.g. at 80°C. The cured paint films are hard and flexible with good single-coat adhesion and good resistance to solvents and water. view less | |

This product has a non-volatile content (1g / 1h / 125°C / convection oven) of 38-42, a viscosity at 23°C, D=approx.45s-1 of max. 200, and a pH (1:3 in demineralised water) value of 7-9. On account of its outstanding mechanical and chemical resistance, the product is particularly suitable for the formulation of sealers for mineral substrates and reactive resins (EP, PUR), in particular when good hot tire resistance is required. 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. view less | |

It can also be used in combination with suitable melamine resins for the formulation of one-component coatings. This product has a viscosity at 23°C, D=approx.40s-1 of 1,500 - 3,000, a non-volatile content (1g / 1ml toluene / 1h / 125°C) of 44-47, and a pH (1:4 in demineralised water) value of 7-8. This product can be used primarily in combination with Bayhydur® 304, XP 2487/1 and Desmodur® N 3900 for air- and oven-drying industrial coatings. The cured coating film is hard, tough but flexible and exhibits high gloss, good filling power, good weather and light stability, good resistance to solvents and gasoline and rapid drying. It is not recommended for clearcoat applications for wood. view less | |

This product has a pH (1:3 in demineralised water) value of 8-9, an acid value of 8-11.2, and a hydroxyl content solvent-free, calculated to approx. 3. Bayhydrol® A 2651, combined with aliphatic polyisocyanates is well suited for the formulation of high gloss and matt clear 2K polyurethane coatings, as well as pigmented coatings. The product was developed in particular for the formulation of two-component wood coating systems. It is characterized by very good film transparency and high wood warmth. Crosslinking with Bayhydur® XP 2487/1 or XP 2655 yields coatings with very high chemical resistance. view less | |
