A co-solvent free, flame retardant, aliphatic, aqueous polyurethane dispersion.

Suggested Uses: HD-2313 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 HD-2313 will enable synthetic fabrics to pass various FR tests including NFPA-701, MVSS-302, & others. HD-2313 is well suited for use in textile coatings, such as automotive upholstery, that require outstanding strength and fire retardancy without the use of antimony-oxide/decabrome chemistry. Using HD-2313, 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. The high solids and solvent-free nature of HD-2313 make it a very cost effective urethane.

Characteristics:
  • Permanent, non-leaching flame retardancy
  • Contains no co-solvent
  • Excellent cost/performance ratio
  • Soft, tough, flexible, dry film
  • Excellent low temperature flex crack resistance
