A soft, halogen-free, flame retardant, aliphatic, polyurethane dispersion.

Suggested Uses: L-3192 was designed for use as a coating or finish for synthetic textile fabrics that must have permanent flame retardancy. This unique urethane dispersion is manufactured at high solids and without the use of solvent. Low add-on levels of L-3192 will enable synthetic fabrics to pass various FR tests including NFPA-701 and MVSS-302. L-3192 is well suited for use in textile coatings, such as automotive upholstery, that require outstanding strength and flame retardancy. Using L-3192, a coating can be formulated to pass MVSS-302 and maintain required strength properties at a much lower coating weight than conventional coatings. This results in a much softer hand and possible cost savings.

Characteristics:
  • Permanent, non-leaching flame retardancy.
  • Halogen free.
  • Excellent cost/performance ratio.
  • Soft, tough, flexible, dry film.
  • Excellent low temperature flex crack resistance.
  • Contains n-methyl pyrrolidone (NMP).
