Nano gold colloids with good stability

Our client said Nano colloidal gold and gold nanoparticles of Hongwu are unrivaled – we found that your company the best that we could work with.”

Colloid gold solution possesses unique properties such as good optical characteristics, biocompatibility, and catalytic activity. 

High hardness, wear-resisting zirconia ceramic dolly is the best choice in the milling of electron, printing ink, paint, coating which require high and no pollution.

Titanium dioxide, rutile, 30-50nm, surface treatment, have hydrophilic and oleophylic two kinds. 

Zinc oxide (ZnO) Nanoparticle can be used for anti-UV with excellent performance. Nano size zinc oxide ZnO powder has optical, electrical, magnetic, thermal, sensitive and other properties that conventional coarse sizes do not have. Hongwu Nano long-term mass production and supply of high stable quality nano zinc oxide materials.
