Hauthane L-3155
A self-crosslinking, aliphatic, water-based polyurethane dispersion designed for use in high performance concrete and wood floor coatings.
Suggested Uses: L-3155 employs a unique air-dry, self-crosslinking mechanism to impart chemical-resistance, abrasion-resistance and mar-resistance properties which equal or exceed those of two-component, water-based floor coating systems currently used in the market.
Characteristics:
- One-component, self-crosslinking polymer
- High level of toughness, abrasion- and mar-resistance
- Outstanding water and chemical resistance
- Excellent exterior weathering performance
- Contains n-methyl pyrrolidone (NMP) co-solvent

Application
L-3155 can be used as a sole vehicle or blended with acrylic emulsions for spray or rotogravure applications. Rheology modifications can be made with associative thickeners for alternative application methods.
Drying
Ambient drying temperatures between 60 – 90 ºF are ideal to produce coatings with optimal film properties.
