Hauthane HD-2117
An extremely hard, aliphatic, polyester-based, aqueous polyurethane dispersion with exceptional chemical and early water-resistance properties.
Suggested Uses: HD-2117 was designed for topcoat applications on a wide variety of substrates, including concrete, metal, plastic and wood. HD-2117 produces films with exceptional adhesion to aluminum, excellent leveling properties and high levels of chemical resistance.
Characteristics:
- Outstanding water and chemical resistance
- Fast early water resistance development
- Can be crosslinked to enhance performance
- Dilution and clean-up with ordinary tap water
- Contains n-methyl pyrrolidone (NMP) co-solvent

Application
| HD-2117 can be used as a sole vehicle or blended with acrylic emulsions for spray or rotogravure applications. Rheology modifications can be made with associative thickeners for alternative application methods. |
Drying
HD-2117 may be dried at ambient temperatures with supplemental co-solvent addition of 5 % DPM or DPnB on total formulation weight. Typical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties without additional co-solvent.
