## Description

J-B Weld Hi-Temp Red Silicone Gasket Maker & Sealant is an RTV (Room Temperature Vulcanized) Silicone gasketing material designed for use in mechanical assemblies where the existence of higher, continuous temperatures up to 550°F or 650° intermittent might exist. Upon curing, which occurs when the product is exposed to the moisture in the air, the silicone forms a tough, waterproof seal on most surfaces. It will not shrink or crack, resists weathering, is sensor safe, and is great for many automotive 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
