Dear Sir,

any standard book on rubber compounding ingredients will contain chapters on additives among which antistatic agents. Sooner I will provide with some references. Regards

In most cases antistatic reagents are not used as coatings but as filler or additive for plastics or rubbers. Some antistatic reagents are dependent on humidity of the air, like glycerol monostearate, ethoxylated amines derived from fatty chemistry, salts of sulfonates (Li salts especially effective) or compounds with a quarternary ammonium ion. Not dependent on air humidity are conductive fillers, like carbon black. They must be applied in a amount slightly below percolation of the filler (some weight-%, must be determined by experiments). At higher concentration the composite becomes conductive. Other conductive fillers are indium tin oxide (for colorless compounds) or conductive polymers like PEDOT or polyaniline. They can be also used as coatings but coating of rubbers require high elastic films what is difficult to put into practice.
