Hauthane HD-2101
A soft, aliphatic, polyester-based, aqueous polyurethane dispersion.
Suggested Uses: HD-2101 was designed primarily for use on flexible substrates as a coating, saturant or impregnant.
Characteristics:
- Outstanding toughness and abrasion resistance
- Excellent water and chemical resistance
- Exceptionally high melting point for a medium soft polymer
- Can be crosslinked to enhance performance
- Dilution and clean-up with ordinary tap water
- Contains n-methyl pyrrolidone (NMP) co-solvent

Application
| HD-2101 can be used as a sole vehicle or blended with harder polyurethane dispersions or acrylic emulsions for spray or rotogravure applications. Rheology modifications can be made with associative thickeners for alternative application methods. |
Curing
HD-2101 can be air dried, if desired, depending on film thickness. Typical drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
