Verabschiedete Gutachten und bisherige Konsultationen zu Zulassungsanträgen


This page provides further information on the applications for authorisation or review reports, which have undergone consultation. The applications for authorisation are in the opinion development phase until the final opinions of the Committees for Risk Assessment and Socio-economic Analysis have been adopted and sent to the European Commission. The European Commission's decision-making process can be followed through the comitology register, where further information is published about the REACH Committee's past and upcoming meetings.

Substance Details

Potassium hydroxyoctaoxodizincatedichromate
EC Number
CAS Number
Entry Nr in Annex XIV
Use name
Use of potassium hydroxyoctaoxodizincatedichromate in paints, in primer, sealants, and coatings (including as wash primers)
Broad information on use applied for (conditions of use and function)
Surface coating of articles with paints, primers, sealants and coatings (including as wash primers) containing potassium hydroxyoctaoxodizincatedichromate. These surface coatings are applied to protect the part from corrosion and improve adhesion between metal and composite parts. They may be applied during production, maintenance or repair.

The key function of potassium hydroxyoctaoxodizincatedichromate in the surface coatings is corrosion inhibition.

The coating material generally contains < 10% hexavalent chromium by weight. The formulated product is delivered to the industrial facility in sealed containers. The size, geometry and area of the article to be coated determine the coating technique to be used. The coating material may be applied to the component by spray application using a spray gun and/or by brush application (local/roller application). The paint is applied either automatically or manually by a trained operator within a designated area. Sometimes a coating may be 'touched-up’ during maintenance or repair operations in- or outside a designated facility by small brush.

Concentrations of Cr(VI) in the surface coating may be below or above detection levels.
