An NMP-free, APEO-free, aliphatic, polyester-based, water-borne polyurethane dispersion.

Suggested Uses: L-2942 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

N/A L-2942 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

N/A The addition of coalescing solvent is recommended to achieve optimal film formation with L-2942. 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.
