Hauthane HD-2125
A hard, chemical-resistant, polyester-based, aliphatic, polyurethane dispersion.
Suggested Uses: HD-2125 was developed for use on flexible and rigid PVC and other plastic substrates. It may also be formulated to provide gloss topcoats on cementatious, metal and wood substrates. This product exhibits superior chemical resistance properties, while maintaining excellent flexibility and gloss retention characteristics.
Characteristics:
- Superior adhesion to PVC
- Excellent UV resistance
- Exceptional alcohol resistance
- Humidity resistance
- Contains n-methyl pyrrolidone co-solvent
