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.

Structure

  • 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.
