Strontium chromate is contained in SEEVENAX Low VOC Primer 113-07, Grundbeschichtung 113-22 and 113-82, Primer 313-01 (including FlatPack) and 313-81. SEEVENAX Grundbeschichtung 113-25 contains potassium hydroxyoctaoxodizincatedichromate. The CELEROL WashPrimer 913-21 wash primer contains pentazinc chromate octahydroxide and potassium zinc chromate. The coatings are applied wet-on-wet with short drying and a minimal content of volatile organic compounds. The systems are matched to each other, comply with the specifications of leading OEMs and keep protection under regular contact with fuel and other chemicals.
How to choose
The choice starts with the question of whether chromates are acceptable. Chromate grades are used in the EU only under REACH authorizations and only in the aerospace sector, so for supplies to Ukraine this status is important to check in advance. Chromate-free products of the same portfolio should be considered as an alternative. For the outer layer over the primer look at ALEXIT BaseCoat/ClearCoat.
