Restore Your Vehicle's Integrity with a Reliable Seal
Permatex Black Silicone Adhesive Sealant provides a reliable, general-purpose RTV seal for both indoor and outdoor automotive use. This black sealant effectively bonds, repairs, seals, mends, and secures a variety of materials including glass, metal, plastics, fabric, vinyl, and weather stripping. It also protects electrical wiring and can be applied to horizontal or vertical surfaces, ensuring versatility in repairs.
Engineered for resilience, this sealant is waterproof and flexible, offering resistance to water, weather, vibration, and grease. Its impressive temperature range of -75°F to 450°F (-59°C to 232°C) makes it suitable for demanding automotive environments. Surfaces may require clamping for approximately 1 hour until the silicone is firm, ensuring a strong, lasting bond.
Suggested applications span windshields, door frames, electrical connections, seams, roofs, vinyl tops, and weather stripping. Each pack contains two 3 oz (88.7ml) tubes, providing ample material for multiple repairs. All customs duties and GST are included in the listed price, with delivery via ExpressBox tracked shipping.
Engineered for Automotive Durability
Permatex Black Silicone Adhesive Sealant is specifically formulated for the rigorous demands of automotive repair. Its RTV (Room Temperature Vulcanizing) silicone composition ensures a flexible, waterproof, and vibration-resistant bond that stands up to harsh weather and temperature extremes. Unlike generic adhesives, it's sensor-safe and designed to adhere securely to a wide range of automotive materials, including glass, metal, plastics, and vinyl, offering reliable sealing for windshields, seams, and electrical components. This pack of two 3 oz tubes ensures you have enough for multiple projects, providing a cost-effective solution for maintaining your vehicle's integrity.
Ideal for Indian Automotive Repairs
This sealant is well-suited for the varied Indian climate, resisting water, weather, and vibration effectively. It performs reliably from -75°F to 450°F (-59°C to 232°C), handling both the heat of Indian summers and cooler conditions. While excellent for general automotive sealing, those needing a high-strength structural bond for critical chassis repairs might consider specialized epoxies. For cosmetic trim or weather stripping, this silicone sealant is a robust choice. Surfaces may require clamping for about an hour until firm.
