Surface coating material, antistatic

Polyurethanes with antistatic properties are suitable for use where static electrical charges must be dissipated. The polyurethane must be compounded to provide the antistatic properties throughout the whole bulk of the material. The antistatic agent, if a liquid, must not migrate to the surface readily. Surface coating the item is not desirable, as the effect is only temporary.

This discussion will focus on chemical antistats and excludes inorganic conductive additives such as carbon black, metal-coated carbon fiber, and stainless steel wire. Chemical antistatic additives can be categorized by their method of application (external and internal) and their chemistry. Most antistats are hydroscopic materials and function primarily by attracting water to the surface. This process allows the charge to dissipate rapidly. Therefore, the ambient humidity level plays a vital role in this mechanism. With an increase in humidity, the surface conductivity of the treated pol5uner is increased, resulting in a...

These compositions must provide surface resistivity 10 < R < 10 (Qcm). The early efforts, to achieve the optimum surface resistivity, such as coating the polymeric parts with electrostatic dissipative materials, addition of either graphite, metal particles or fibers, incorporation of low molecular weight antistatic agents etc., did not yield fruitful results [Kozlowski, 1995]. Antistatic properties are observed for materials having either -SH or -OH groups e.g., phenolic, alcoholic, or acidic).
