Abstract: A method of preparing an antistatic coating exhibiting a desired value of surface resistivity which is substantially stable with respect to time takes as its starting point a commercial antistatic product having a synthetic resin base and substantially free from metallic particles but of which the surface resistivity, measured after mixing with its hardener and drying, is very much below the desired value. A compatible insulating resin is added to this product so as to raise the surface resistivity, still measured after mixing with the hardener and drying, to a value much higher than the desired value. The resulting product is then subjected to an accelerated ageing treatment causing a reduction in surface resistivity with terminal asymptotic development to the level of the desired value. Such a coating may be applied to radomes and other aircraft surface elements, and has the advantage that its conductivity does not increase appreciably with age.
