Bochemie Nano Zinc Oxide

logo bochemie 

Bochemie nano zinc oxide has unique functional properties such as antimicrobial, antifouling, vulcanizing, anticorrosive, photo-catalytic, UV protection, piezoelectric, etc.

Bochemie have developed a unique production technology of nano ZnO with extremely high surface area. The resulting technology is environmentally friendly, and thanks to its parameters, the product is among the most advanced nanomaterials.

 The functional properties of the nano ZnO have been tested in different application sectors (plastics, paints, filters, cosmetics, etc.). The tests are performed directly at industrial partners and in collaboration with prominent academic experts. Compared to the classical oxide, Bochemie nano ZnO is more environmentally friendly.  There are applications, especially in the rubber industry, where Bochemie nano ZnO can replace classic ZnO with 4x less addition rate, whilst maintaining or even improving the functional properties. 

Alongside the nano ZnO in powder form. Bochemie have also developed three types of aqueous dispersions (differing in the nano ZnO content and the type of  dispersant system), and one organic dispersion (PMA solvent).
