Request Information
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
