L-2245

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

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.

 

CHARACTERISTICS:

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