Hauthane L-2183
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.
Characteristics:
- Low activation temperature (200 ºF)
- Can be crosslinked to improve bond strength and heat-resistance.
- Non-crystalline nature
- Contains n-methyl pyrrolidone co-solvent.
