Product Uses
  • This unique urethane dispersion is manufactured at high solids and without the use of solvent.
  • Low add-on levels of L-3808 will enable synthetic fabrics to pass various FR tests including NFPA-701 and MVSS-302. L-3808 is well suited for use in textile coatings, such as automotive upholstery, that require outstanding strength and flame retardancy. Using L-3808, a coating can be formulated to pass MVSS-302 and maintain required strength properties at a much lower coating weight than conventional coatings. T
  • his results in a much softer hand and possible cost saving
Product Applications
  • L-3808 may be sprayed or pad applied as supplied.
  • Rheology may be modified with alkali-swellable or associative thickeners for alternative application methods.

Technical Details & Test Data

Drying

This product displays excellent strength properties as supplied, but the use of a crosslinker such as melamine-formaldehyde (3-6 phr) for elevated temperature-curing or carbodiimide for low temperature-curing may be added to enhance performance.
