Hauthane L-2245 Anionic and aliphatic waterborne polyurethane Hauthaway PU - Polyurethane dispersions (PUDs) ADHESIVE An anionic, aliphatic, aqueous polyurethane dispersion with a low activation temperature. L-2245 is an adhesive grade polyurethane suggested for industrial laminating applications . 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° F. Heat activation will occur between 215 – 225° F. L-2245 may be crosslinked with polyaziridines, water dispersible polyisocyanates, epoxy silanes or low temperature melamines to increase bond strength and heat resistance. Anionic, aliphatic, aqueous polyurethane dispersion for industrial laminating adhesive and for bonding plasticized vinyl sheet. Offers low activation temperature, low level of n-methyl pyrrolidone and non-crystalline nature. Can be used as supplied or blended with vinyl acetate/ethylene, styrene butadiene and acrylic emulsions. May be modified with associative or acrylic thickeners.
