The start of Honjo Chemical’s first production of zinc dust in Japan was successful which led to secure a major share in the market accumulating expertise in this field.
Zinc dust and zinc oxide are in production since the start of the company.

Zinc dust

Characteristics ・Usage

One of the characteristics of our zinc dust is less than 10μm and can change the size of the product according to particle size by applying our exclusive processing technology.
Zinc dust is mainly used in anti-corrosion paints for marine containers and ships, as well as for large buildings; it is also used for specific purpose such as a reducing agent in organic synthesis and desulfurizing in metal refining.
In compliance with increasingly strict environmental regulations, we also offer low Pb and low Cd products.

Various zinc oxide products are available based on the French method zinc oxide manufacturing technology.
Zinc oxide is used in electronic materials such as ferrite and varistors, and as a raw material for alkaline and manganese dry cells in addition to the use as a vulcanization accelerator for rubber products.
MMS-7B-4 is now available for use in anti-corrosion paints which is supplied to paint manufacturers.

Nano-sized ultra-fine zinc oxide particles are transparent to visible light and have excellent absorption effects against ultraviolet rays when dispersed.
It is widely used in cosmetics, PET films, textiles and others.
Products are available with two different specific surface areas: 60m²/g and 100m²/g.

Specific surface area	60m²/g・100m²/g　Specific surface area measurement device
True specific gravity	5.6g/cm³

Visibility of the transmitted light is almost transparent.
Ultraviolet rays, on the other hand, show a remarkable absorption at about 380nm which is an absorption edge of zinc oxide. (See left graph).
