'Fine Metal Powders Co' manufactures by its own original technology fine zinc, copper and bronze powders
These materials can be used in:
- paint-&-varnish materials production;
- as components of powder paints;
- for thermal diffusion zincing;
- for gas-flame, gas-plasmatic gas-dynamic and other methods of spraying
- as catalysts of chemical processes;
- as components of solder and pastes for electronic industry;
- as components of antifriction and anti-wear preparations and so on.
Production reaches industrial scale.
