J-B WELD® white silicone sealant and adhesive is a general-purpose sealant adhesive RTV (room temperature vulcanized) silicone designed for use in household or mechanical assembly applications. Upon curing, which occurs when the product is exposed to the moisture in air, the silicone forms a tough, waterproof, mildew and mold-resistant seal on most surfaces. It will not shrink or crack, resists weathering, is sensor safe and is great for many household and automotive applications.

Optimum Black combines maximum oil resistance with maximum flexibility. Today, we see components changing and unlike materials meeting (plastic/steel, aluminum/steel etc), all with different rates of expansion and contraction. In addition, with technology advancing, regulations and requirements tightening, we see thinner metals, fewer fasteners and wider spread bolt patterns. The strength and flexibility of Optimum Black handle the changes and added stresses that exist between today's lightweight, high-performance and premium component assemblies. Optimum Black is sensor safe, low odor and non-corrosive with resistance to oil, shop fluids and vibration. It is one of the most advanced, maximum flex, maximum oil-resistant RTV silicone gasket makers available.
