An anionic, aliphatic, aqueous polyurethane dispersion.

Suggested Uses: L-2183 is an adhesive grade polyurethane suggested for modifying industrial laminating adhesives. L-2183 may also be used in low tack pressure sensitive applications.

  • Low activation temperature (200 ºF)
  • Can be crosslinked to improve bond strength and heat-resistance.
  • Non-crystalline nature
  • Contains n-methyl pyrrolidone co-solvent.

N/A L-2183 can be used as supplied or blended with vinyl acetate/ethylene, styrene butadiene and acrylic emulsions. The rheology of L-2183 may be modified with associative or acrylic thickeners for knife-over-roll or similar methods.


N/A L-2183 may be crosslinked with carbodiimides, polyaziridines, water dispersible polyisocyanates, epoxy silanes or low temperature curing melamines to increase bond strength and heat resistance.
