Hauthane HD-2142 DMM
An NMP-free, APEO-free, aliphatic, polyester-based, water-borne polyurethane dispersion.
Suggested Uses: HD-2142 DMM was developed for use on flexible and rigid PVC, and treated polypropylene film. Coatings containing this polymer form hard, tough, hydrolysis-, chemical- and stain-resistant films. Superior adhesion to PVC makes it the ideal candidate for vinyl sheet goods, automotive interior parts, vinyl furniture and components.
Characteristics:
- Superior adhesion to PVC and treated polypropylene film
- Excellent UV resistance
- Exceptional alcohol resistance
- Humidity resistance
- Contains dipropylene glycol dimethyl ether (DMM) co-solvent

Application
HD-2142 DMM may be used as a sole vehicle or blended with acrylic emulsions. Viscosity modification can be made with associative thickeners for application via spray, knife-over-roll, or other methods.
Curing
The addition of coalescing solvent is recommended to achieve optimal film formation with HD-2142 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 oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
