Zinc rich paints are paints in which the zinc metal pigments functions as the active anticorrosion component. It is present in the dry paint film at levels of 85-92 wt%. It is due to these high levels of zinc metal pigments that the paint has the qualities of a metallic zinc film which allows the paint to protect the steel by a multiple mechanism of barrier, cathodic and physico-chemical protection.
For other applications (e.g. shop primers) where a short term protection is needed (6 months to 1 year), the zinc content is considerably lower.
For many decades zinc rich paints have been considered to be the most effective anti-corrosion paint systems in use, and have a proven excellence in this application. The thickness of these zinc primers can vary between 6 and 125 microns: the higher the thickness and the higher the zinc content, the longer they may provide the anti-corrosion protection to the steel.
The main application area of zinc powder paints is in the anti-corrosion protection for industrial construction (steel infrastructure, pipelines, bridges, windmills, off shore rigs, petrochemical and power industries.…) and the anti-corrosion protection for marine applications (sea containers, construction and maintenance of ships and marine equipment).
As the leader in the field of Fine Zinc Powders EverZinc is developing new products and is investigating Fine Zinc Powder applications. This is described in a number of publications : China Coating Journal July 2009 and March 2010; JPCL March 2013 and December 2015; Nace 2009; PCE January 2012; Wind Technology March 2012; ECS Nurnberg 2013.

Zinc Metal Pigments (ZMP) are extensively used in mechanical plating / galvanizing, whereby small steel parts (screws, fasteners, rivets, bolts,…) are coated with a very thin uniform layer of zinc, providing enhanced corrosion protection without the introduction of hydrogen embrittlement.
Sherardizing is an application to put a zinc coating on small steel parts, this application is similar to Mechanical Plating but applies at higher temperature (380-450° C).
Fine Zinc Powders are used in many chemical applications.
EverZinc is the world’s leading fine zinc powder producer and supplier of zinc powders used in chemistry. As the market leader, EverZinc is continuously looking for innovative fine zinc powders for the life science market.

Sodium Hydrosulphite-based reducing agents are mainly used in three sectors:
• Paper industry: bleaching of mechanical pulp, de-inked pulp and kaolin clay
• Textiles: reducing vat dyes (indigo), decolourising dyes, bleaching fibres, yarn and fabrics
• Specialist chemicals: a powerful reducing agent used in the chemical and pharmaceutical industries, metals and antioxidants.
