Drizzling is an innovative process for the application of chrome-free passivation products for all metals.
During the trade fair Aluminium, that took place from 27th to 29th September 2022 in Düsseldorf (Germany), ALIT Technologies has showcased its new dosing and application system for the passivation of metal components Drizzling.
As it is extremely compact and easy to install, it allows to apply a constantly fresh and contamination-free passivating solution to the products. Drizzling is a complete dosing system capable of automatically managing the mixing of demineralised water coming from a feed tank with the exact quantity of passivating chemical product, thus obtaining an optimal and always fresh solution to be dispensed directly on the surface of metals.
The use of special atomizing nozzles and compressed air enables the Drizzling system to homogeneously produce and distribute a fine and light mist of passivating solution that completely envelops the product, even in 7-meter vertical lines for aluminium profiles.
It can be combined with chrome-free chemicals, including titanium and polymer based ALFICOAT 748/3 from ALUFINISH GMBH & Co. KG, in order to guarantee excellent results in the passivation process both in terms of corrosion protection and paint adhesion.
