Hauthane HD-4675

A hard, co-solvent free, aliphatic, polyester polyurethane dispersion.

Suggested Uses: HD-4675 was designed for topcoat applications on a wide variety of substrates, including concrete, metal, plastic and wood.


  • Contains no co-solvent
  • Produces clear, durable films with low levels of co-solvent (<100 g/l)
  • Excellent non-yellowing properties
  • Good water and chemical resistance
  • Produces tough, abrasion and mar resistant films

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.
