Polyurethane Dispersions are the binder of choice in many more coatings applications than you might imagine.
Water-based polyurethane dispersions put the stain-resistance in automotive interior plastic paints, the lubricity in fly-fishing line coatings, the durability in general aviation hanger floors, and the crispness in sail cloth.
They come with a wide variety of performance characteristics that allow the formulator to fine tune the preferred coating properties. In fact, if you haven't imagined polyurethanes in your formulation, you're missing the opportunity to impart abrasion- and chemical-resistance, toughness, flexibility and a lustrous finish to your coating.

Hauthane Polyurethane Dispersions are available in:
Aromatic Grades - Based on unsaturated isocyanates, these grades are very economical, but yellow with exposure to UV light.
Co-solvent free Grades - Provide the formulator with a very low VOC content base resin. Some grades will require the addition of co-solvent to attain optimal film formation at ambient temperatures.
Flame Retardant Grades - Polymer chains contain unleachable, halogen components to reduce flame spread on coated textiles. Coatings based on these products provide true color capability.
LAMINATING ADHESIVE GRADES - Designed for laminating film to paper, film to film and film to foil composites.
Polyester-Based Grades (NMP-containing) - Contain n-methyl pyrrolidone co-solvent. Generally, polyester-based grades offer enhanced chemical and stain-resistance properties over polyether-based products.
Polycarbonate-based (NMP-containing) - Provide superior hydrolytic stability versus polyester and polyether-based grades in standard hydrolysis testing.
NMP-free (DMM-based) / APEO-free Grades - An alternative to traditional NMP-based products, these grades offer the possibility of formulating "eco-friendly" coatings.
OH-functional Grades - Intended for use in 2-part coatings systems with water-dispersible isocyanates.
