For those, consider specialized products. ## How to use 1. Clean and dry all surfaces thoroughly. Remove old sealant, oil, grease, and dirt. Ensure the area is well-ventilated and free of moisture before application. — Prepare Surfaces 2. Cut the tube nozzle to create a bead of approximately 1/8 to 1/4 inch (3-6 mm). Apply a continuous bead to one surface, ensuring even coverage without gaps. — Apply Sealant 3. Immediately assemble the parts, allowing the sealant to squeeze out slightly. Wipe away excess sealant. Allow the adhesive to cure tack-free for 1 hour and fully for 24 hours before use or exposure to fluids. — Assemble and Cure ## Product details | Field | Value | |---|---| | Key Feature | High-Temperature Resistance | | Continuous Temperature Rating | 204°C (400°F) | | Intermittent Temperature Rating | 260°C (500°F) | | Chemical Resistance | Oils, water, weather, vibration, grease | | Adhesion Surfaces | Stainless steel, aluminum, glass, metal, plastics, fabric, vinyl | | Full Cure Time | 24 hours | | Tack-Free Time | 1 hour | | Specific Uses | Automotive gasket maker, sealing engine parts, electrical insulation, ductwork, doors, windows | | Cost per use | 80 ml tube at ~1 ml/application = ~80 applications: ₹18.61 per application | | Shelf life after opening | 12 months (typical for RTV silicone) | | Contraindications | Not for painted surfaces; avoid direct skin contact during cure; ensure adequate ventilation. | | Allergens / common irritants | May cause skin irritation; contains lead (California Prop 65). | | Brand | Loctite | | Model Number | 37460 | | Color | Black | | Material | Silicone | | Container Type | Tube | | Item Form | Liquid | | Volume | 80 ml (2.7 Fl Oz) | | Weight | 0.1 kg (0.25 lbs) | | Country of Origin | China | | Water Resistance Level | Waterproof | | California Proposition 65 | Contains lead; Cancer, Reproductive | ## Attributes - **Item form:** Liquid ## Frequently asked questions ### Is Loctite 37460 Black RTV Silicone safe for automotive sensors? This Loctite RTV silicone is designed for automotive use and offers good resistance to oils and vibration. While it is not explicitly labeled as 'sensor-safe' or 'low-volatility' like some specialized oxime-cure silicones, it is commonly used for gasket making and sealing around engine components. For applications directly adjacent to oxygen sensors or sensitive electronics, always check the product's specific cure type and manufacturer recommendations to avoid potential corrosion. ### What temperature can this bonding_adhesive withstand? The Loctite 37460 Black RTV Silicone Adhesive Sealant can withstand continuous temperatures up to 204°C (400°F) and intermittent temperatures up to 260°C (500°F). This high-temperature resistance makes it suitable for demanding automotive applications like engine gaskets and exhaust system seals, where it will perform reliably even under the heat generated in Indian traffic conditions. ### How to use Loctite 37460 Black RTV Silicone Sealant? Ensure surfaces are clean, dry, and free of oil and grease. Apply a continuous bead of sealant (approx. 1/8 to 1/4 inch thick) to one surface. Assemble parts immediately, allowing sealant to squeeze out. Remove excess sealant. Allow to cure tack-free for 1 hour and fully for 24 hours before exposing to fluids or stress. ### What is the best bonding_adhesive for automotive use in India? For automotive use in India, Loctite 37460 Black RTV Silicone Adhesive Sealant is a strong choice due to its high-temperature resistance and ability to bond to various automotive materials like metal and rubber. It withstands oils, water, and vibration common in Indian driving conditions. Imported from the USA, it offers a reliable alternative to local brands for critical sealing applications. ### Can I use this bonding_adhesive for general household repairs? While Loctite 37460 Black RTV Silicone is versatile, it is specifically formulated for automotive applications and high-temperature resistance. It can bond to glass, metal, and plastic. However, for general household repairs like bathroom tiles or window frames, a standard silicone caulk might be more appropriate and cost-effective. This product's strength lies in its ability to withstand engine bay conditions. ### What are the side effects of bonding_adhesive?
