Hauthane L-2892
An extremely hard, NMP-free, APEO-free, aliphatic, polyester-based, aqueous polyurethane dispersion with exceptional chemical and early water-resistance properties.
Suggested Uses: L-2892 was designed for topcoat applications on a wide variety of substrates, including concrete, metal, plastic and wood. L-2892 produces films with exceptional adhesion to aluminum, excellent leveling properties and high levels of chemical resistance.
Characteristics:
- Contains dipropylene glycol dimethyl ether (DMM) co-solvent
- Outstanding water and chemical resistance
- Fast early water resistance development
- Can be crosslinked to enhance performance

Application
| L-2892 can be used as a sole resin vehicle or blended with acrylic emulsions for spray or rotogravure applications. Rheology modifications can be made with associative thickeners for alternative application methods. |
Drying
L-2892 may be dried at ambient temperatures with supplemental co-solvent addition of 5 % DPM or DPnB on total formulation weight. Typical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties without additional co-solvent.
