TECHNICAL SPECIFICATIONS

Ferrinov®-500 is a dark brown ferrite pigment with exceptional anticorrosion properties.

This pigment initially shows a certain activity and releases metal ions when subjected to a corrosive environment. These ions form stable hydroxides that cover the metal in a continuous process. The passive layer then formed consists mainly of zinc hydroxide and, to a lesser degree, of calcium hydroxide. This pigment is also characterized by an electrochemical protection mechanism linked to its zinc content. The pigment is colour stable up to 400°C, and shows no significant chemical change at 1,000°C.

Ferrinov®-500 has a very narrow grain size distribution. The median particle size is less than 0.30 µm. These particles are clusters of nanoparticles. They have a very long term passivation activity. This pigment has a moderately high alkalinity.

Ferrinov®-500 is easily dispersed and compatible with all paint systems.

The key parameters of the hydrometallurgical process are systematically checked at all the manufacturing stages. The resulting pigment is then controlled in terms of pH levels, conductivity, specific weight, moisture, oil absorption, dispersion, incorporation speed and colour. This continuous quality control process ensures the consistency and quality of each production lot.
