Octylphosphonic acid

OPA 80% is an 80% solution 1-octyl phosphonic   acid / OPA 97% is a 97% version of 1-octyl phosphonic acid. The material is used as a surface modifier, chelant and in the sodium and potassium salt forms has surfactant properties useful in the formulation of hard surface cleaners.

 

Application: Pigments
Surface Modification

  • Pearlescent pigments
  • Metallic flake pigments
  • Pigments become suitable for powder coating formulations
  • OPA improves luminance and flop of powder formulations
  • Improved chroma results. Example data below:
