Hauthane HD-2142

DESCRIPTION: 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.

Drying

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.
