Description
Hexafluorotitanic acid (CAS 17439-11-1, EC 241-460-4), also known as fluorotitanic acid or hydrogen hexafluorotitanate, is an inorganic acid supplied as an aqueous solution with the formula H2TiF6. It carries no assigned E-code and is classified under HS code 2826199090 for customs purposes.
In metal surface treatment, hexafluorotitanic acid reacts with metal oxides to form a thin titanium-fluoride conversion layer that improves adhesion and inhibits corrosion on aluminium and steel substrates. In electronics manufacturing, it functions as an etchant and surface modifier, conditioning metal surfaces at a chemical level to ensure uniform coating adhesion in printed circuit board production.
This product is available in industrial-grade aqueous solution and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm concentration specifications and SDS documentation prior to ordering, as supplied grades may vary by application.
