Hauthane HD-2101 DMM
A soft, aliphatic, polyester-based, aqueous polyurethane dispersion.
Suggested Uses: HD-2101 DMM was designed primarily for use on flexible substrates as a coating, saturant or impregnant. HD-2101 DMM may also be used as a blending resin with harder polyurethane dispersions to impart flexibility without adversely effecting chemical resistance.
- 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 water
- Contains dipropylene glycol dimethyl ether co-solvent

HD-2101 DMM 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.
|The addition of coalescing solvent is recommended to achieve optimal film formation with HD-2101 DMM. In ambient-cured systems the addition of 5 – 10 % DPnB 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 produce optimal film properties. HD-2101 DMM may be crosslinked with carbodiimides, water-dispersible isocyanates or polyaziridines to further enhance performance.|
