A low cost, aromatic, polyether-based, aqueous polyurethane dispersion.

Suggested Uses: HD-3011 is a highly versatile coatings and adhesive polymer for applications where lightfastness is not critical. Its dry surface and high melting point properties prevent blocking problems. Excellent for use as a solvent (MEK) reactivate-able adhesive for bonding and laminating applications. Compatible with acrylic and other aqueous polymers for optimum cost/performance balance.

Characteristics:
  • Medium soft, tough, flexible film
  • Unusually dry surface for non-blocking applications
  • High melting for thermal stability
  • Can be crosslinked with melamines or aziridines for true thermoset character and increased adhesion.
  • Excellent hydrolytic stability
  • Contains n-methyl pyrrolidone (NMP) co-solvent

Application

N/A HD-3011 can be used as a sole vehicle or blended with acrylic emulsions for spray, dip, or rotogravure applications. It can be thickened with associative thickeners for alternative application methods.

Curing

N/A HD-3011 can be air dried at ambient room temperatures. Typical drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
