Hauthane L-2961
A soft, NMP-free, APEO-free, aliphatic, water-borne, polyurethane dispersion.
Suggested Uses: L-2961 was designed for use in textile applications as a versatile polyurethane coating. Due to its overall properties, L-2961 can be used as a finish or a coating for many textile applications. This product is ideally suited for use as an anti-fray finish on textile fabrics that must have a soft hand. L-2961 is also suitable for textile coating applications that require excellent low temperature flexibility and crack resistance.
Characteristics:
- Forms soft, flexible, dry films
- Excellent UV-resistance
- Good abrasion resistance
- Superior low temperature flexibility and crack resistance
- High melting point (320 ºF)
- Contains dipropylene glycol dimethyl ether (DMM) co-solvent
