PRODUCT DESCRIPTION

Permatex Ultra Black Gasket Maker is a single component,

room temperature, vulcanizing, gasketing compound desi

gned to provide reliable "formed-in-place" gaskets for me

chanical assemblies. This material cures on exposure to mo

isture in the air to form a tough, flexible, silicone rubber

gasket. The product resists aging, weathering and thermal

cycling without hardning, shrinking or cracking. Designed

to provide increased oil resistance and complies with ex

tended warranty requirements.

PRODUCT BENEFITS

● Improved oil resistance

● Sensor safe, non-corrosive

● Good adhesion and flexibility

● Replaces most cut gaskets

● Can be used as a gasket maker or dressing

● Non-flammable, Non-toxic

● Low odor

TYPICAL APPLICATIONS

● Pump housings

● Machine tools

● Compressors

● Gearboxes

● Valve covers

● Oil pans

● Transmission pans

DIRECTIONS FOR USE

For assembly as a form-in-place gasket

1.Remove all previous material from mating surfaces

   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.

   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 sur

   face, first tracing the internal areas of the gasket configu

   ration, 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 least

   one quarter to one half turn.

9.For best results, allow to cure overnight.

For assembly as a gasket dressing

1.Repeat steps 1 through 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 silicon film.

4.Apply a second thin film to pre-cut gasket surface.

5.Remove any excess and assemble parts immediately.

   Note:Product is 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) counterc

   lockwise.

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.

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 pro

   duct using either the above "silicone plug" method or 

    using the included plastic cap.

For Cleanup

1.Remove uncured product from parts and hand-tools with

   Permatex Envirosafe ODC Free Cleaner/Degreaser. If skin

    ned 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.
