The effects of milling standard phosphate-based anticorrosive pigments to nanoparticle size have been investigated. Notably, the finer particles were able to approach the metal surface more closely when formulated into a primer. Several different tests in an epoxy primer confirmed that the nanoparticles gave better corrosion resistance than the standard form of the same pigment.
