POWERSIL® 403 has been developed for manufacturing the outer conductive film on cable accessories for transmission and distribution cables. The product yields a conductive coating characterized by high elasticity, good mechanical properties and scrub resistance. This makes the dispersion suitable even for cable fittings to be installed via cold-shrink processes. The product contains no aromatic compounds such as toluene.
The new POWERSIL® 403 silicone rubber dispersion likewise forms this kind of electrically conductive film. The two-component formulation contains addition-curing silicone rubber, which adheres well to the insulating silicone substrate while forming a flexible film. Elongation at break is roughly 650 percent for this formulation, and its tear strength is 20 newtons per millimeter. This means that a conductive film made from POWERSIL® 403 can withstand extreme elongation – without cracking – such as occurs during the production and installation of cable accessories suitable for cold-shrink processes.
The product also meets increasingly frequent demands for formulations that contain no aromatics and, as such, are more user friendly. POWERSIL® 403 is free of aromatic solvents such as toluene. The low-viscosity liquid can be easily applied by spraying, dipping, or brushing. Its electrical properties also make the dispersion suitable for use in antistatic coatings for textiles.
