## Description

J-B Weld Black Silicone Sealant & Adhesive is a general purpose RTV (Room Temperature Vulcanized) Silicone, designed for sealing and bonding uneven surfaces. Upon curing, which occurs when the product is exposed to the moisture in air, the silicone forms a tough, waterproof seal on most surfaces. It will not shrink or crack, resists weathering and is great for many automotive accessories and household applications.

Review: Excellent Sealant for Multiple Uses - This product is a great product for sealing leaks, bonding materials, or weatherproofing. I used it on a cracked window frame, and it held up perfectly against rain and wind. The clarity is excellent, and it doesn’t shrink after drying. Works on glass, metal, and plastic very handy to have around
