Request Information
An aliphatic, APEO-free, co-solvent free, polyether-based, polyurethane dispersion.

Suggested Uses: L-3037 was designed for base coats or intermediate coats intended for plating/embossing. Films based on this polymer exhibit excellent print retention properties.

Characteristics:
  • Excellent print retention properties
  • Contains no co-solvent
  • Produces soft, tough films
  • Good water and solvent-resistance for a soft polymer
  • Dries to clear, glossy film

Application

N/A L-3037 can be used as a sole vehicle or blended with acrylic emulsions intended for plating applications for spray or roll coating applications. Rheology modifications can be made with associative thickeners.

Curing

N/A L-3037 can be forced dried, if desired, depending on film thickness. Typical drying temperatures and dwell times for aqueous finishes are sufficient to produce optimal film properties.
