Powerbead Ultra Grey RTV Silicone 9.5oz

Powerbead Ultra Grey RTV Silicone 9.5oz is a professional-grade elastomeric sealant engineered for demanding sealing and bonding applications across automotive, industrial, and maintenance sectors. Designed for technicians and contractors who require a reliable, gap-filling sealant that cures to a flexible, durable bond, this product excels in high-temperature and high-vibration environments. The ultra-grey formulation provides excellent visibility during application and blends seamlessly with grey components, making it ideal for engine gaskets, valve covers, transmission pans, and thermal management assemblies.

As a room-temperature vulcanizing (RTV) silicone sealant, Powerbead Ultra Grey cures through moisture exposure, forming a resilient elastomer that resists oil, coolant, and solvents commonly encountered in automotive and industrial settings. The silicone base chemistry delivers superior adhesion to both metal and composite surfaces without the need for additional primers, while the non-corrosive formulation protects sensitive electronics and sensor assemblies. With a 9.5oz capacity per cartridge, this sealant provides adequate coverage for multiple sealing tasks, and the aerosol dispensing format ensures consistent bead application and reduces waste during installation.

Professionals across OEM assembly lines, independent repair shops, and heavy equipment maintenance operations trust Powerbead Ultra Grey for gasket replacement, surface sealing, and thermal isolation work. The product is compatible with standard 9.5oz cartridge guns and applicator tools, enabling rapid deployment in high-volume production or field repair settings. Full cure typically occurs within 24 hours under normal conditions, though partial handling strength develops within hours, allowing work resumption on time-sensitive projects.
