Dar-Tech Hauthane HD-4675 is a hard, co-solvent-free, aliphatic polyester 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 supplied or blended with acrylic emulsions for spray, dip, or rotogravure applications. It can be thickened with associative thickeners for knife-over-rolling or similar methods.

- Application Method & Curing
HD-4675 can be used as supplied or blended with acrylic emulsions for spray, dip or rotogravure applications. It can be thickened with associative thickeners for knife-over-roll or similar methods.. Due to the co-solvent free nature of HD-4675, the addition of coalescing solvent is recommended to achieve optimal film formation. In ambient-cured systems the addition of 5-10% coalescing solvent is suggested. Less coalescing solvent is required in heat-cured systems to attain comparable film properties. Typical drying temperatures and dwell times for aqueous coatings are sufficient to optimize film characteristics.
