J-B Weld 31310 Silicone Adhesive Sealant High Strength Gel 3 oz Clear Seal, bond, and protect with confidence using the J-B Weld 31310 Clear Silicone Adhesive Sealant, a high-strength, RTV (room temperature vulcanizing) gel designed for reliable performance in both household and mechanical applications. This 3 oz clear gel formula creates a durable, waterproof bond on a wide range of materials including steel, ceramic, glass, rubber, cloth, and most plastics, making it ideal for repairs, sealing, and assembly tasks around the home, garage, or workshop. Formulated as a high-strength gel, this silicone sealant resists shrinking, cracking, and peeling over time, maintaining its integrity under temperature fluctuations and environmental stress. Once applied, it cures upon exposure to moisture in the air, forming a tough, permanently flexible seal that remains effective for up to 10 years. The clear dry color ensures a clean, nearly invisible finish?perfect for aesthetic-sensitive areas. With a service temperature range of 32F to 400F, this sealant performs reliably in extreme hot and cold conditions, making it suitable for use near engines, exhaust components, appliances, and outdoor fixtures. It is heat resistant, moisture resistant, and mold mildew resistant, ensuring long-term protection in damp or humid environments such as bathrooms, kitchens, and marine settings. The sealant reaches tack-free status in approximately 60 minutes (1 hour) and fully cures in 24 hours. It can be applied in temperatures between 40F and 100F for optimal adhesion and curing performance. Its slight odor dissipates quickly during cure, and with a low VOC content of 3 g/L and a flammability rating of 0, it offers a safer, more environmentally conscious option for indoor use. Weighing 0.300 lb and packaged in a 3 oz cartridge, the product is lightweight and ready for use with a standard caulking gun. The gel consistency allows for precise application with minimal drip or sag, even on vertical or overhead surfaces.
