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.

Research projects were already implemented for:
- mixed self-assembled layers of phosphonic acids
- low adhesion, non-wetting phosphonate self-assembled monolayer films formed on copper oxide surfaces
- study of the self-assembling of n-octylphosphonic acid layers on aluminum oxide
- fabrication of DNA nanowires by orthogonal self-assembly and DNA intercalation on a Au patterned Si/SiO2 surface
Shelf Life
Under proper storage conditions, the shelf life is 12 months from the certification date.
