Request Information
A partially bio-renewable resource based, NMP-free, soft, aliphatic, water-borne, polyurethane dispersion.

Suggested Uses: L-3360 was designed for use in textile applications as a versatile polyurethane coating. Due to its overall properties, L-3360 can be used as a finish or a coating for many textile applications. This product is ideally suited for use as an anti-fray finish on textile fabrics that must have a soft hand. L-3360 is also suitable for textile coating applications that require excellent low temperature flexibility and crack resistance.

Characteristics:
  • 50 % bio-based, renewable resource content
  • Superior flexibility
  • Produce soft, tough, flexible, dry films
  • Good UV resistance
  • Very good abrasion resistance
  • Superior low temperature flexibility and crack resistance
  • Contains n-ethyl pyrrolidone (NEP)
