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 285ºC or 340ºC intermittent might exist.
Upon curing, which occurs when the product is exposed to 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.
