LubrizolR2063

Product Type      Metal Adhesion Promoter

Product Performance         2063 is a phosphate ester with a polyester backbone. Since phosphate esters can bond with metal surfaces, Lubrizol 2063 improves the adhesion of oil-based and water-based paints to metal substrates, with particularly good results on aluminum, as well as on cold-rolled steel and galvanized steel. It also enhances the flexibility and corrosion resistance of the paint film. 2063 can be widely used in coating systems.

                  
     2063 offers the following advantages:

                     ◆ Adhesion     (including adhesion after water immersion and condensation tests)

                        ◆ Improved flexibility of the paint film   ◆ Enhanced corrosion resistance

Application Range     ◆ Industrial Coatings                                            ◆ Heavy-Duty Protective Coatings

                          ◆ Can and Coil Coatings                                 ◆ Acid-Curing Primers

                    Can be used in the following systems:

                ◆ Acrylic/Melamine, oil-based and water-based;

                   ◆ Polyester/Melamine, oil-based and water-based

                   ◆ Alkyd Resins, oil-based and water-based                   ◆ Epoxy Resins, oil-based and water-based

                   ◆ Two-Component Polyurethane and Polyurethane Emulsions             ◆ Acrylic Emulsions

Addition Method    Lubrizol 2063 is a viscous liquid. It is recommended to add it during the grinding stage or incorporate it with high-speed stirring or slow addition during the paint mixing stage. For water-based systems, it can be neutralized to pH 7 with ammonia water first, or added directly to a system that already contains ammonia water. This product has acid functionality, which acts as a catalyst, promoting cross-linking of amino paints during baking. Therefore, the amount of catalyst can be reduced, or the baking temperature can be lowered.

Dosage        Typically added at 1-2% (W/W) of the total formulation. In some cases, up to 3% of the total amount may be required. The optimal dosage is determined through testing to achieve the desired adhesion.
