A partially, renewable resource-based, hard, aliphatic, polyester-based, aqueous polyurethane dispersion with good chemical and water-resistance properties.

Suggested Uses: L-3369 was designed for topcoat applications on a wide variety of substrates, including concrete, metal, plastic and wood. L-3369 produces glossy films with excellent leveling properties and good stain- and chemical-resistance to a variety of household food and cleaning products.

Characteristics:
  • 42 % bio-based, renewable resource content
  • Good water and chemical resistance
  • Low VOC content (75 g/L less water)
  • Can be crosslinked to enhance performance
  • Dilution and clean-up with ordinary tap water

Application

N/A L-3369 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.

Curing

N/A L-3369 is a film former at 70 ºF and may be applied at lower temperatures with supplemental co-solvent addition of 3 - 5 % hexylene glycol 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. The performance of L-3369-based coatings may be enhanced with carbodiimide and aziridine crosslinkers.
