A very hard, aliphatic, polyester polyurethane dispersion.

Suggested Uses: HD-2120 was developed for use on flexible and 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 n-methyl pyrrolidone co-solvent

Application

N/A HD-2120 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 HD-2120. In ambient-cured systems the addition of 5 - 10 % 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.
