All-Purpose Acetic RTV Silicone Sealant – Black


Discover the perfect balance of strength, flexibility, and reliability with GENERAL AUTOSIL — your trusted solution for sealing mechanical assemblies with confidence.


Formulated as a single-component, acetic-cure, room temperature vulcanizing (RTV) compound, GENERAL AUTOSIL cures upon contact with moisture in the air to form a durable silicone rubber seal. Its non-sagging, paste-like consistency ensures smooth application on both horizontal and vertical surfaces, bonding instantly to a wide range of materials such as metal, glass, wood, plastic, silicone resin, ceramic, and more.


Once cured, GENERAL AUTOSIL becomes a resilient, waterproof, and UV-resistant barrier that won’t shrink, crack, or degrade over time — even when exposed to extreme temperatures or mechanical vibrations. This makes it ideal for both automotive and general-purpose use, where durability and precision matter most.
