Permatex 81724 Ultra Blue Multipurpose RTV Silicone 95g

Permatex 81724 Ultra Blue Multipurpose Rtv Silicone 95g

Permatex Ultra Blue RTV Silicone Gasket is a single
component, room temperature vulcanizing gasketing
compound designed to provide reliable “formed-in-place”
gaskets for mechanical assemblies. This material cures on
exposure to moisture in the air to form a tough, flexible,
silicone rubber gasket. The product resists aging, weathering
and thermal cycling without hardening, shrinking or cracking.
Designed for superior bonding properties to oil contaminated
metals as compared to other formed-in-place gaskets, and
maintains outstanding oil resistance. NSF White Book
registered.

DIRECTIONS FOR USE

For assembly as form-in-place gasket

1. Remove all previous material from mating surfaces.
   Permatex Gasket Remover is recommended for most
   materials.
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 1/16 inch to 1/8 inch bead of silicone
   to one surface, first tracing the internal areas of the
   gasket configuration, then all surrounding bolt holes.
6. Assemble parts immediately while silicone is still wet.
7. Finger tighten flange only until material begins to seep
   out the sides of the flange.
8. Allow to set for at least two hours and re-torque at lease
   one quarter to one half turn.
9. For best results, allow to cure overnight.

For assembly as gasket dressing

1. Repeat steps 1 thru 4 as in previous section.
2. Apply a thin film of silicone to one surface to be sealed.
3. Place the pre-cut gasket onto silicone film.
4. Apply a second thin film to pre-cut gasket surface.
5. Remove any excess and assemble parts immediately.

Note: Product not recommended for use as a cylinder
head gasket or head gasket sealant.

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. Assemble parts immediately while silicone is still wet.
6. Finger tighten flange only until material begins to seep
   out the sides of the flange.
7. Allow to set for at least two hours and re-torque at least
   one quarter to one half turn.
8. For best results, allow to cure overnight.
9. To close, turn extension nozzle clockwise until tight
   (about one full turn). Wipe off excess material from
   nozzle and replace black cap.

For Cleanup

1. Remove uncured product from parts and hand-tools with
   Permatex® Fast Orange® Wipes or Fast Orange® Hand
   Cleaners. If skinned over, break film with a dry cloth to
   remove as much as possible. Remove the remaining
   material with Permatex® Gasket Remover.
2. Clean hands with a dry cloth or Permatex Fast Orange
   hand cleaner.

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.

TYPICAL CURING PERFORMANCE

Permatex Ultra Blue No-Leak RTV Silicone Gasket cures on
exposure to moisture in the air. The product dries tack free in
two hours and fully cures in 24 hours. Cure times will vary
with temperature, humidity and gap.

Chemical / Solvent Resistance

The product retains effective properties in contact with
automotive fluids, such as motor oil, transmission fluids,
alcohol and antifreeze solutions. Note: Not recommended for
parts in contact with gasoline.
