Hauthane L-2245

An anionic, aliphatic, aqueous polyurethane dispersion with a low activation temperature.

Suggested Uses: L-2245 is an adhesive grade polyurethane suggested for industrial laminating applications where a pre-lamination coating is applied to a substrate and then dried. Ideal for bonding plasticized vinyl sheet to itself and to other substrates such as rubber, wood, cardboard and textiles.


  • May be crosslinked for improved adhesion and heat-resistance.
  • Non-crystalline nature
  • Low level of n-methyl pyrrolidone (NMP) co-solvent (~2 %)

L-2245 can be used as supplied or blended with vinyl acetate/ethylene, styrene butadiene and acrylic emulsions. The rheology of L-2245 may be modified with associative or acrylic thickeners for knife-over-roll or similar methods.


L-2245 will dry to a tack-free film in 10 minutes at 200 ºF. Heat activation will occur between 215 – 225 ºF. L-2245 may be crosslinked with polyaziridines, water dispersible polyisocyanates, epoxy silanes or low temperature melamines to increase bond strength and heat resistance.
