Its performance is equal to the traditional conversion coating. Features 　Process name 　Main features 　TRIVALENT 100 　(Appearance type blue chromate) 　· A strong consistent blue can be obtained. 　· Because of one solution, it is easy to control with the wide control range. 　TRIVALENT 300 　(Corrosion resistance type blue chromate) 　· A consistent blue can be obtained. 　· The corrosion resistance is excellent. A film with high adhesion can be  　obtained. 　· Quick treatment in low temperature is possible. Its control range is wide. 　TRIVALENT 400 　(Corrosion resistance type yellow chromate) 　· A light consistent yellow can be obtained. 　· The corrosion resistance is excellent. A film with strong resistance to  　scratches and dents can be obtained. 　· Especially appropriate for barrel operations. 　TRIVALENT 600 　(Corrosion resistance type yellow chromate) 　· A consistent yellow can be obtained. 　· A film with the excellent heat resistance and corrosion resistance can be  　obtained. 　· Because of one solution, it is easy to control with the wide control range. 　Rust-proof plating New zincate bath　|　Zinc-cobalt-iron ternary alloy plating 　| Trivalent chromium conversion coating - TRIVALENT series　|
