How long do conductive properties last?
This is an interesting question. A quality product should provide a lifetime of service. Likewise, conductive properties should last for the life of the product. Some “dissipative’ vinyl products, however, require regular recoating with antistatic floor finish in order to maintain acceptable electrical properties. These should be avoided unless the solution does not need to be a long-term one. Some ESD carpets require periodic applications of a topical treatment containing antistat. The problem with applying the antistat is that the maintenance crew doesn’t always know when it is time to reapply the antistat or when the humidity conditions might be too low for adequate performance from a surface additive. Fortunately, there are many products that will provide unlimited electrical performance without any use of maintenance additives. Make sure you read the fine print.
