DEVELOPMENT OF POLYMERIC COATINGS WITH ULTRA DIELECTRIC AND ANTICORROSIVE PROPERTIES

摘要

The invention relates to the synthesis of new homo and copolymers containing urea linkages at laboratory and pilot scale. Further these polymers with fillers and different additives have been used to formulate and manufacture products and coatings for commercial applications for different industries like, Power Generation and Transmission, heavy engineering industry, electronic hardware manufacturing industry, petrochemical and chemical manufacturing industry, etc. These coatings and products have been tested as per the national and international standards to meet the stringent requirements of the industry. They have very high tack properties on the substrates like copper metal wire and sheets. We have found that such polymers have not been used for electrical applications. These polymers have been used for coating applications on electrical appliances and electrical conductors where the requirement is of very high mechanical properties as well as high performance electrical properties. The mechanical properties required for such applications are of very high tensile strength and elongation. It is found that the electrical properties required for the polymer to posses are like high dielectric strength, low dielectric constant, high volume & surface resistivity and very low dissipation factor.
