Work Zone High Temperature Silicone Sealant

• Work Zone High Temperature Silicone Sealant is a 100% silicone polymer with no organic fillers.
• Colors available: Red, Black.
• Sizes: 300 ml cartridges, 18.9 liter pails, and 200 liter drums.
• Grade: gun grade, nonsagging.

It is long lasting, and forms a weatherproof & watertight seal, which remains permanently flexible, and will not shrink, crack, crumble or dry out. The sealant has good resistance to weathering, vibration, moisture, ozone and extreme temperatures. It may be applied in subzero weather without loss of extrusion or physical property characteristics and is effective from - 62°C to 204°C. It is easy to apply, finger smoothable, and nonflammable.

The high temperature properties of this sealant make it ideally suited for use on chimneys and fireplaces where the temperature does not exceed 500°F on a continuous basis, on engines or other applications as a temporary or permanent gasket material, sealing and encapsulating heating elements in appliances, aerospace gasketing, moving oven belts, industrial ovens, bag filters on smoke stacks, and more. Use it on any application for critical bonding, sealing, potting, encapsulating and protective coatings where parts must perform at high temperatures.

This product is not for use as a fire stop sealant. Not recommended for continuous water immersion, or where abrasion and physical abuse are encountered. Do not apply to porous surfaces, such as masonry, or on building materials that bleed oils or solvents, such as certain impregnated woods and certain partially vulcanized rubber gaskets, tapes or adhesives. Do not use in totally confined spaces, because the sealant needs atmospheric moisture to cure. Do not use in aquariums as the bio agents in the sealant may be toxic in solution. Paint does not adhere well to silicone. Not recommended for use on or near sensitive metals such as copper, brass, zinc, carbon steel, galvanized iron or magnesium; these metals may be corroded, especially in confined cure conditions, due to the acetic acid released during the cure process. Before product application, user should determine suitability of High Temperature Silicone for intended use.

• Joints: Maximum joint size recommended is 13mm (½”).
• Surface Preparation: Thoroughly clean and degrease all surfaces. Then rinse all surfaces, except plastic, with acetone. Rubber surfaces should be roughened with sandpaper, then wiped with acetone.
• Joint Backing: Use only backing materials or bond breakers capable of withstanding expected service temperatures of the application. Consult manufacturer of backing materials or bond breakers to ensure that material is appropriate for use on specific application. Backing material should be used in joints over 9mm (3/8”). Bond breaker should be used in shallower joints to prevent three sided adhesion.
• Weather Considerations: Do not apply to exterior surfaces if rain is expected within 24 hours.
• Service Time: Let dry 24 hours before exposing to water.
• Cleanup: There is no commercial solvent which will dilute uncured silicone, so care must be taken when applying. Wipe excess uncured silicone away carefully with a soft cloth.
