1. TBA Electro Conductive Products Ltd Electrically Conducting Coatings Presented by Mark Lineker- Technical Sales Manager (TBA ECP)

2. TBA Electro Conductive Products supplies a wide range of coatings modified with a variety of conductive fillers. These coatings are tailored to provide varying degrees of electro-conductivity and are especially suitable for use in applications where protection from static electricity and electromagnetic interference (EMI) is required. The coatings have been developed for optimum adhesion to a wide variety of substrates. Conventional plastics are normally electrically insulating materials which typically exhibit surface resistances of 1012 - 1016 ohms per square. Introduction to Conductive Coatings

3. Introduction to Conductive Coatings Static dissipative Coatings Surface resistivities between 106 and 1010 ohms per square, for use in applications where slow , controlled and low energy dissipation of electrostatic charges is required. For example ATEX (Explosive Atmosphere) and electronics applications. Conductive Coatings Surface resistivities of less than 106 ohms per square, designed to meet the requirements of EN 61340 (specifications which refer to the protection of electronic components from electrostatic damage). EMI Shielding Coatings Volume resistivities less than 1 ohm-cm and up to 55 dB attenuation of EMI radiation. SALES 01706
