An experimental, non-halogenated, aliphatic, water-borne polyurethane dispersion.

Suggested Uses: L-2728 was developed for use on un-primed, un-treated flexible TPO. Coatings containing this polymer form tough, flexible films. Excellent adhesion to TPO makes it the ideal candidate for sheet goods used in upholstered furniture, canopies, signs and other fabricated articles.

Characteristics:
  • Very good adhesion to un-primed, flexible TPO
  • Good water and humidity resistance
  • Good UV-resistance
  • Good chemical resistance
  • Contains n-methyl pyrrolidone co-solvent
