Description

VersaChem® High Temp Red RTV Silicone

High-Temperature Gasket Maker & Sealant for Automotive & Industrial Applications

VersaChem® High Temp Red RTV Silicone is a premium, one-component, moisture-curing RTV (Room Temperature Vulcanizing) silicone gasket maker built to deliver durable, flexible, leak-proof seals in demanding high-heat environments. Once cured, it forms a tough silicone rubber gasket that stands up to continuous thermal cycling, vibration, moisture, oil, and weather exposure — without shrinking, hardening, or cracking over time.

Designed for automotive, heavy equipment, marine, industrial, and general maintenance use, this high-performance silicone is a reliable alternative to conventional paper, cork, felt, and rubber gaskets. It’s oxygen sensor safe and formulated with low volatile content, making it well suited to modern engine assemblies.

As an authorized distributor of VersaChem products, White House General Trading supplies genuine sealing and repair solutions across the UAE, GCC, Middle East, and Africa — supporting workshops, fleet operators, OEMs, industrial maintenance teams, and manufacturing facilities.
