Request Information
Soft, aliphatic, water-borne polyurethane dispersion in a blend of DMM and propylene glycol solvents.

Suggested Uses: L-2985 was designed for use in textile applications that require a soft hand coupled with very good strength, abrasion resistance, excellent adhesion, and excellent resiliency. Due to its overall properties, L-2985 can be used as a finish or a coating. This versatile urethane is ideally suited for use as a finish for nylon and polyester threads and as a coating for nylon and vinyl substrates. L-2985 is also ideally suited for textile-coating applications that require excellent low temperature flex crack resistance. The low melt temperature also allows L-2985 to be used as a heat seal coating. When properly formulated, L-2985 can be used as a coating for awning fabrics, boat cover fabrics, and other architectural fabrics.

Characteristics:
  • NMP-free, APEO-free
  • Superior flexibility
  • Soft, tough, flexible film
  • Good abrasion resistance
  • Superior low temperature, flex-crack resistance
  • Low melting point (265 ºF)

Application

N/A L-2985 may be used as a sole vehicle or blended with acrylic emulsions. Viscosity modification can be made with associative thickeners for application by spray, knife-over-roll, or other methods.

Curing

N/A Typical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties. Do not use crosslinking agents for heat-seal coating applications.
