PURPOSE AND CHARACTERISTICS OF VIRES ELECTROCONDUCTIVE PAINTS
The increasing use of plastic containers for electronic equipment, has gradually highlighted a major drawback: plastic material is much less efficient than metal in shielding from electromagnetic interferences, with obvious negative consequences on the various electronic components.
This is due to the fact that plastic is an insulating material, and therefore cannot discarge electrostatic charges. These charges form arcs which can damage, and sometime cut electrical circuits.
Sources of interferences are several: from the most obvious, like lightnings and storms, to marcy others, like high and low tension trestles, telephone switchboards, TVs, vacuum cleaners, etc.
Even car manufacturers have discovered that this phenomenon can be very dangerous, as it is often responsible for sudden electric and electronic failures of car engines, that cannot be otherwise explained.
Considering the growing use of plastic material, it appeared obvious that a different solution to the problem had to be found. Researches showed that the application of a special electroconductive paint would build a kind of Faraday cage over plastic containers, shielding electronic components from EMI and ESD.
Electroconductive paints are based on metallic pigments and special resins.
The shielding capacity is measured by a 0 to 120 Decibel scale, with the following values:
- from 0 to 40 DB very low shielding
- from 40 to 80 DB satisfactory shielding
- over 80 DB very satisfactory shielding.
A 50 microns coating by conductive paint, with a resistivity of 0.2-0.4 sq.ohm. will grant a 65-75 DB shielding, which is considered satisfactory by most US and West-German researchers.
At present electroconductive paints are widely used in almost all electronic sectors for container coating, and their application will most probably spread to automotive production for shielding of electronic equipment, now present in all vehicles. The advantages involved are marcy: fuel saving, better performance of the braking circuit, improved efficiency of acoustic signals, telephones, air-conditioning, lower maintenanee work, improved general reliability.
VIRES has developed and currently produces several types of electroconductive paints, suitable for application on plastic materials, metals, glass.
VIRES electroconducti ve paints are both cold-water, and solvent diluted paints. Drying can take place in open air, at 120°C oven, and at higher temperatures. On plastic surfaces it is advisable to use a primer under the electroconductive coating.
