Dar-Tech Hauthane HD-4669 is a hard, co-solvent-free, aliphatic, aqueous polyurethane dispersion. It was designed for topcoat applications on a wide variety of substrates, including concrete, metal, plastic, and wood. This grade can be used as a sole vehicle or blended with acrylic emulsions for spray, dip, or rotogravure applications. It may be thickened with associative thickeners for alternative application methods.

- Application Method & Curing
HD-4669 can be used as a sole vehicle or blended with acrylic emulsions for spray, dip or rotogravure applications. It may be thickened with associative thickeners for alternative application methods.. Due to the co-solvent free nature of HD-4669, the addition of coalescing solvent is recommended to achieve optimal film formation. Heat curing will also improve film properties. Typical drying temperatures and dwell times for aqueous coatings are sufficient to optimize film characteristics.
