Daotan VTW 1250/40WA Polyurethane Solutia PU - Polyurethane dispersions (PUDs) DAOTAN® Waterborne polyurethane with solvent-borne performance. The DAOTAN VTW family of waterborne polyurethane dispersions meets or exceeds the performance of high quality solvent-borne urethanes in a variety of industrial applications, while offering the ability to create a low volatile organic compound (VOC) formulation (<350 grams per liter of VOC). Uses DAOTAN VTW formulations are used in the following applications: Demanding metal applications such as high-performance wall paints, implement enamels, aircraft coatings High-performance floor coatings Secondary containment coatings Anti-graffiti coatings Metal clearcoats Industrial maintenance coatings Automotive and non-automotive transportation coatings Performance Advantages The unique polymer creates very hard films with several performance advantages over solvent-borne urethane. Key features of DAOTAN VTW for waterborne paints and coatings include: Quick drying Quick hardness development Excellent durability Excellent weatherability Good flow and leveling High gloss Excellent stability Superior mar and scratch resistance Excellent adhesion to metal and wood substrates Excellent adhesion to cement substrates and epoxy topcoats and primers Chemical and abrasion resistance Flexibility Hardnes DAOTAN VTW 1250/40WA Aromatic Polyurethane-dispersion modified with drying fatty acids Sole-binder for corrosion-protection-systems because of it's rapid dry and through cure along with excellent corrosion protection and good compatibility with acrylic dispersions Yellow brown liquid supplied 40 % in Water containing also 4.6% N-Methylpyrrolidon ; neutralized with 0.2 % ammonia, as salt. Daotan VTW 1250 is shear stable. For the manufacture of primers the recommended milling facility is a pearl mill. During milling some of the amine may evaporate and should be replaced before final viscosity adjustment. Post-neutralization with ammonia to a pH range of 8.0 -9.0 (measured in a 10% aqueous resin concentration) should be performed in order to ensure good paint stability. Heucophos ZP 10 has been found to offer excellent corrosion protection with DaotanVTW 1250 without compromising stability. This product does require driers such as Additiol VXW 6206 to obtain optimum properties. Aromatic polyurethane dispersion modified with drying fatty acids. Provides quick drying, quick hardness development, very good durability and weatherability, good flow and leveling, high gloss, very good stability and superior mar and scratch resistance. Offers chemical and abrasion resistance, flexibility, hardness, shear stability, rapid dry, through cure, very good corrosion protection and good compatibility with acrylic dispersions. Gives very good adhesion to metal and wood substrates, to cement substrates and epoxy topcoats and primers.
