    Product Description

    Supex High Temperature Gasket Silicone Adhesive Sealant is a ready to use, single component, room temperature, vulcanizing adhesive/sealant for making 500ºF to 600ºF gaskets and seals. Uncured Supex™  High Temperature Gasket Silicone Adhesive Sealant is a red, viscous, non-sag, low volatile paste which emits a small amount of acetic acid (vinegar like odour) while curing to a flexible rubber. The material cures on exposure to atmospheric moisture to provide a tough, flexible, waterproof, oil-resistant silicone rubber seal. It is specially formulated to meet the low silicone volatiles requirements of the automotive industry for 600ºF flange sealants. The non-sag properties of this ready-to-use sealant allows its use on vertical as well as horizontal surfaces.

    Uses of High Temperature Gasket Silicone sealant 

    Applications for both plant maintenance and small, medium and large-sized OEM include:

    • High temperature (600ºF) Adhesive – Bonds most all substrates including silicone rubber.
    • Gasket dressing and sealant to up-grade conventional metal and specialty pre-cut gaskets that often fail at 600ºF.
    • Formed-in-place Gasket/Sealant to replace pre-formed gaskets that fail to function up to +600ºF.
    • Seal and encapsulate heating elements in electrical appliances up to 500ºF continuous operation.
    • Sealant and adhesive for assembly and repair of industrial furnaces, ovens, boilers, exhaust stacks and high temperature ducting up to 500ºF continuous operation

    USE AND APPLICATION

    This product is specifically formulated for gasketing and sealing where high temperatures (600ºF) are experienced such as exhaust manifolds – crossovers, high temperature
    ovens and furnaces. Applications where sealing and bonding are required under frequent exposure to temperatures above
    450ºF to 600ºF would be the proper application for Supex  High Temperature RTV Silicone Adhesive Sealant. As a formed-in-place gasket/sealant Supex  High
    Temperature RTV Silicone Adhesive Sealant has been designed to give outstanding performance in typical automotive gasketing applications including valve covers, oil pans, water pumps, end seals, and rear axle housings. Excellent adhesive for bonding and repairing fabricated silicone gaskets.

    How to use High temperature RTV Silicone sealant 

    Clean all mating surfaces with MEK, Acetone or water based cleaner prior to applying High Temperature RTV Silicone Adhesive Sealant. Supex Paint stripper or plastic scrapper is recommended to remove all old gasketing material from mating surfaces. Finally, clean and dry the surfaces with Cleaner & Degreaser or mineral spirits.
    Apply  High Temp RTV Silicone Adhesive Sealant in a continuous bead around all holes and perimeters of mating parts. Then assemble parts within 5 minutes by
    mating the two surfaces. Press or clamp firmly (do not slide parts together). The sealant will become tack-free on the exposed surfaces in less than one hour after application. A 1/4 inch diameter bead exposed to atmospheric  moisture cures in approximately 24 hours. Clean up and Removal Uncured High Temp RTV Silicone Adhesive
    Sealant should be cleaned up immediately with Cleaning Solvent or mineral spirits. Cured silicone rubber can be cut away with appropriate scrapers.

    What is red silicone used for?

    Supex Red RTV (Room Temperature Vulcanizing) Silicone Adhesive is the simple way to seal, protect, bond, insulate and waterproof. Superb for forming instant, custom-shaped gaskets, Red RTV Silicone adheres to most materials used in the industrial, electrical, metalworking and construction industries

    Is RTV silicone high temp?

    Supex High-Temp Red RTV Silicone Gasket Maker is formulated for high temperature applications or heavy-duty use such as towing. … Resists auto and shop fluids, with a temperature range of -65° F to 600° F intermittent.

    Does silicone melt or burn?

    While most plastics will begin to melt at high temperatures, silicone does not have a melting point and remains solid until combustion occurs. At high temperatures (200-450oC), silicone rubber will slowly lose its mechanical properties over time, becoming brittle.

    Can you use silicone on exhaust?

    You can use silicone on the joint to the head as it is cooled by the head itself and does not get that hot. The Y piece joints generally run too hot for even the hi temp silicone and it burns off and the joint then tends to leak. The last joint to the rear muffler is normally cool enough again to use silicone.

    Can I use RTV with a gasket?

    Yes, you can. It is called ‘gasket dressing’.In many cases the solid gasket also works as a spacer and can’t be replaced. In such cases,to avoid leakages from flanges we apply silicone on both the flanges and then place ssolid gasket. This ensures 100% leak free joint.
