Permatex Black Silicone Adhesive Sealant

SKU: CS81158PX Category:

Permatex Black Silicone Adhesive Sealant is a room temperature vulcanizing (RTV) substance that is intended specifically for the task of sealing mechanical components.

It is a general purpose, single component adhesive.

You may get it in both Permatex 81158 opaque black and Permatex 80050 transparent clear.

This non-sagging Permatex silicone adhesive sealant produces a robust, flexible, and watertight barrier of silicone rubber after it has been exposed to air moisture and allowed to cure. This seal is resistant to age, weathering, and heat cycling without becoming hardened, cracking, or shrinking.

Warning: Use with caution if you want to use it for motor gasketing.

Listed below are some of the advantages that may be gained by using this high-performance RTV silicone adhesive sealant.

Black silicone adhesive was designed to have a low odor composition, is simple to apply, can be used on either vertical or horizontal surfaces, is waterproof, has exceptional flexibility and stickiness, is insulating, is undisturbed by vibration, is non-toxic, and is non-flammable.

Standard Applications

Permatex Silicone Adhesive Sealant is a high-quality universal sealant/adhesive that may be used with:

Glass, metal, plastic, wood, ceramics, silicone resin, painted surfaces, vulcanized silicone rubber, natural and synthetic fibers, and more may all be repaired using either the clear or black RTV.

All of the following may be bonded, sealed, repaired, and secured with the help of this Permatex black silicone adhesive sealant:

Weather stripping, door frames, windows, housings, vinyl covers and tops, windshields, and lens housings (Clear RTV) may all benefit from regular applications of this RTV sealant for repair and maintenance (Clear RTV, but not for installation.)

The following are the instructions for using Permatex 80050 clear RTV silicone adhesive sealant for assembly applications:

1. Take away anything that might cause a problem with the surfaces joining.
2. For optimal results, thoroughly dry and clean all surfaces using a solvent that leaves no trace, such as Permatex Brake and Parts Cleaner.
3. Permatex black silicone bead diameters may be adjusted by trimming the nozzle to a size between 1/16″ and 1/4″. Beads measuring 1/8 of an inch are often enough for the vast majority of uses.
4. Take off the top, pierce the Permatex clear RTV silicone tube seal or cartridge, and insert the nozzle.
5. In the manner seen below, apply a silicone bead  to one surface that is both continuous and even in thickness.
6. Assemble the components as soon as possible while the silicone is still wet. When necessary, tighten or secure, taking care to prevent extreme squeeze-out.
7. After the substance has had enough time to cure, it will no longer be required to re-torque it.

For Cleanup and Storage

1. Allow the extra material to stretch further than the extension nozzle so that it may dry. This will ensure that the leftover product is sealed and protected from moisture. Simply eliminate the cured substance from the tip for recycling.
2. If Permatex 81158 Black Silicone Adhesive Sealant has not yet dried, wipe it off with a dry cloth; if it has hardened into a skin, break the film with a cloth that is dry to eliminate as much of the substance as possible; and finally, use Permatex Gasket Remover (not on surfaces that are painted) to get rid of what’s left.
3. Use a dry towel or some Permatex Fast Orange Hand Soap to scrub your hands clean.
