A high solids, anionic, aliphatic, aqueous polyurethane dispersion.

Suggested Uses: L-2255 is an adhesive grade polyurethane suggested for industrial laminating applications. Suitable for bonding plasticized vinyl sheet to itself and to other substrates such as rubber, wood, cardboard and textiles.

  • High solids (48%), co-solvent free
  • Can be crosslinked to improve bond strength and heat-resistance.
  • Non-crystalline nature

N/A L-2255 can be used as supplied or blended with vinyl acetate/ethylene, styrene butadiene and acrylic emulsions. The rheology of L-2255 may be modified with associative or acrylic thickeners for knife-over-roll or similar methods.


N/A L-2255 will dry to a tack-free film in 10 minutes at 200 ºF. Heat activation will occur between 235 - 245 ºF. L-2255 may be crosslinked with polyaziridines, water dispersible polyisocyanates, epoxy silanes or low temperature melamines to increase bond strength and heat resistance.
