Since its introduction in 1977 this material has achieved an excellent record for high performance combined with consistency and reliability. It has become the material of choice for manufacturing organic-based electrically conductive coatings that can fully current requirements for electromagnetic compatibility (EMC) - such as those found in EU Directive EEC/336/89.

NOVAMET Conductive Nickel Flake HCA-1 is compatible with both solvent and water based paint systems as well as with conductive ink and adhesive formulations. The product gives smooth, semi-lustrous coatings that can be applied in very thin layers since the flakes are less than 1 µm thick.

This is a high purity filamentary nickel powder produced by the nickel carbonyl process. It is specially screened to optimise size distribution profile. The three dimensional branched structure maximises particle-to-particle contact.

The product is available in two grades - 525 Regular and 525 Low Density.

NOVAMET Type 525 Conductive Nickel Powder is used for the production of conductive paints. It is therefore a complimentary material to HCA-1 Flake. It is often used in situations where relatively thick coatings are required.

NOVAMET also produces a range of high purity spherical nickel powders used in electrically conductive applications. These products have a very tightly controlled particle size distribution together with regular and smooth morphology. Two separate size grades are available:

• Minus 37 microns
  
• Minus 10 microns

Conductive nickel spherical powders are useful where the small particle size is essential, for example in screen printing applications.
