A very hard, NMP-free, APEO-free, aliphatic, polyester polyurethane dispersion.

Suggested Uses: L-2882 was developed for use on rigid PVC. Coatings containing this polymer form hard, tough, hydrolysis-, chemical- and stain-resistant films, which approach 2-component polyurethane performance levels. Superior adhesion to PVC makes it the ideal candidate for automotive interior parts, vinyl furniture and components.

Characteristics:
  • Superior adhesion to PVC
  • Excellent UV resistance
  • Exceptional alcohol resistance
  • Humidity resistance
  • Contains dipropylene glycol dimethyl ether co-solvent

Application

N/A L-2882 can be used as a sole vehicle or blended with acrylic emulsions for spray, dip or rotogravure applications. It can be thickened with associative thickeners for alternative application methods.

Drying

N/A The addition of coalescing solvent is recommended to achieve optimal film formation with L-2882. 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 optimize film characteristics.
