Request Information
Co-solvent free, soft, aliphatic, water-borne, polyurethane dispersion.

Suggested Uses: HD-2024 was designed for use as a cost effective urethane for use in coatings or finishes for textile fabrics. This unique urethane dispersion is manufactured at high solids and without the use of solvent. HD-2024 is well suited for use as a strength additive for acrylic polymers. Whether used alone or as a strength additive, HD-2024 provides increased strength, anti-fray, and abrasion resistance properties at an affordable price.

Characteristics:
  • Co-solvent free and high solids
  • Excellent cost/performance ratio
  • Soft, tough, flexible, dry film
  • Excellent UV resistance
  • Excellent low temperature flexibility and crack resistance
  • Very good abrasion resistance
