Chromium-free Water-based Zinc & Aluminium Coating System

ZICOLLUM™ GMT-320 Silvery White Coating Process

– Chromium-free solution
– Replace dacromet coating as an environmentally friendly water-based coating.
– The coating layer is fine and thin with excellent brightness; the standard thickness is 8-10 µm which is uniform and has no excessive deposition.
– Low VOC emission; comply with REACH & RoHS regulations.
– No acid cleaning and electroplating process is needed, therefore no hydrogen embrittlement of the substrate.
– High efficiency; cost-saving; no dilutor is needed.
– Can reach 320-14,400 hours SST.

ZICOLLUM™ GMT-600 Silvery White Coating Process

– Single component under coating system.
– The coating is fine and thin with excellent brightness; standard thickness is 10 µm, uniform surface and not easy to pile up.
– Low VOC emission; comply with REACH & RoHS regulations.
– No acid cleaning and electroplating process is needed, therefore no hydrogen embrittlement of the substrate.
– High efficiency; cost-saving; no dilutor is needed.
– Can reach 480-6,000 hours SST.

ZICOLLUM™ GMT-1000 Silvery Grey Coating Process

– The coating is fine and thin with excellent brightness, standard thickness is 8-10 µm, uniform surface and not easy to pile up.
– Low VOC emission; comply with REACH & RoHS regulations.
– No acid cleaning and electroplating process is needed, therefore no hydrogen embrittlement of the substrate.
– High efficiency; cost-saving; no dilutor is needed.
– Can reach 720-6,000 hours SST.
