PRODUCT DESCRIPTION S.I.N.: 834-300
Permatex

Clear Silicone Adhesive Sealant is a general
purpose, single component, room temperature vulcanizing
(RTV) compound, designed for the sealing of mechanical
assemblies. Upon curing from the 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.
PRODUCT BENEFITS
• Easy application
• Applied to horizontal or vertical surfaces
• Superior adhesion and flexibility
• Waterproofs
• Insulates
• Unaffected by vibration
• Non-flammable
• Non-toxic

Permatex

Gasket Remover is recommended for most
materials, not for plastics or painted surfaces.
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. A 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.
6. Assemble parts immediately while silicone is still wet.
Secure or tighten as required, avoiding excessive
squeeze-out.
7. Pressure should be applied to parts for 24 hours until
the silicone is fully cured.
Instructions for PowerBead
1. Clean and dry all flange surfaces to be sealed.
2. Remove black cap from top of extension nozzle.
3. Turn nozzle extension one complete turn (360°)
counterclockwise.
4. Depress finger trigger and apply a continuous 1/16 inch
to 1/8 inch PowerBead to one surface.
5. Apply a continuous and even bead of silicone to one
surface.
6. Assemble parts immediately while silicone is still wet.
Secure or tighten as required, avoiding excessive
squeeze-out.
7. Pressure should be applied to parts for 24 hours until the
silicone is fully cured.
8. To close, turn extension nozzle clockwise until tight
(about one full turn). Wipe off excess material from
nozzle and replace black cap.
Storage of Unused Product
1. Create a “Silicone Plug” by allowing excess material to
extend beyond the extension nozzle or aerosol tip to
cure, sealing and protecting the remaining product from
moisture. For reuse, simply remove the cured product
from the tip.
2. For PowerBead dispensers, you may store remaining
product using either the above “silicone plug” method or
using the included plastic cap.
