## Overview

J-B Weld 31314 Red High Temperature RTV Silicone Gasket Maker & Sealant is a professional-grade, 3 oz. silicone adhesive designed for high-heat environments up to 550°F continuous and 650°F intermittent. It air-cures to form a waterproof, weatherproof, and mold-resistant seal that bonds stronger than steel, ideal for automotive repairs, household sealing, and mechanical assemblies.

## 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

## Questions & Answers

**Q: Does this work on stone?**
A: Dear Sir,

Thank you for query,

Above item is useful for industrial equipment gasket making, it remains soft after application not suitable for gap & crack filling in stones. Please confirm your application is to fill the gap between the 2 stone layer or to fill hairline or large crack on one stone surface accordingly we suggest you the right product with detail to order.
