Description

PRODUCT DESCRIPTION
Permatex Black Silicone Adhesive Sealant is a general
purpose, single component, room temperature vulcanizing
(RTV) compound, designed for the sealing of mechanical
assemblies. Upon curing from exposure to moisture in the air,
this non-sagging paste forms a tough, flexible, waterproof seal
of silicone rubber, which resists aging, weathering and thermal
cycling without hardening, shrinking or cracking. Note: Not
recommended for engine gasketing applications.

Permatex
2. For best results, clean and dry all surfaces with a
residue-free solvent, such as Permatex Brake and
Parts Cleaner.
3. Cut nozzle to desired bead size, 1/16“ to 1/4“ in
diameter. An 1/8” bead is usually sufficient for most applications.
4. Remove cap, puncture tube or cartridge seal and attach
extension nozzle.
5. Apply a continuous and even bead of silicone to one
surface, as shown below:
6. Assemble parts immediately while silicone is still wet.
Secure or tighten as required, avoiding excessive
squeeze-out.
7. Re-torque will not be necessary after the product has
cured.
For Storage and Cleanup
1. Allow excess material to extend beyond the extension
nozzle to cure, sealing and protecting the remaining
product from moisture. For reuse, simply remove the
cured product from the tip.
2. Remove uncured product from parts and hand-tools with
a dry cloth, if skinned over, break film with a dry cloth to
remove as much as possible, and remove the remaining
material with Permatex Gasket Remover (not on
painted surfaces) as previously stated.
3. Clean hands with a dry cloth or Permatex Fast
Orange hand cleaner.

TYPICAL CURING PERFORMANCE
