Hauthane L-2996

An NMP-free, APEO-free, polycarbonate-based, hydroxyl-functional, aliphatic, water-borne polyurethane dispersion.

Suggested Uses: L-2996 was developed for use with water-dispersible, isocyanate crosslinkers such as Bayer’s Bayhydur 302 or Perstorp’s Easaqua X D 401. The product, when crosslinked provides tough, chemical resistant, glossy coatings which may be applied to a variety of substrates including concrete, metals, plastics and wood materials. This product exhibits superior chemical resistance, while maintaining excellent flexibility and gloss retention characteristics.

Characteristics:

  • Superior chemical resistance
  • Excellent exterior weathering durability
  • Excellent humidity resistance
  • Contains dipropylene glycol dimethyl ether (DMM) co-solvent

Application

HD-3011 can be used as a sole vehicle or blended with acrylic emulsions for spray, dip, or rotogravure applications. It can be thickened with associative thickeners for alternative application methods.

Curing

HD-3011 can be air dried at ambient room temperatures. Typical drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
