For assembly form-in-place gasket

1. For best results, Remove all previous material from mating surfaces. Clean and dry all surfaces.

2. Cut nozzle to desired bead size, 1/16" to 1/4" in diameter. An 1/8" bead is usually sufficient for most applications.

3. Remove cap, puncture tube or cartridge seal and attach extension nozzle. 4. Apply a continuous and even bead of silicone to one surface, first tracing the internal areas of the gasket configuration, then all surrounding bolt holes as shown below:

5. Assemble parts immediately while silicone is still wet. Secure or tighten to recommended torque specs.

6. Re-torque will not be necessary after the product has cured.

 

For assembly as a gasket dressing

1. Repeat steps 1 through 3 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.

 

For Cleanup

1. Remove uncured product from parts with Cleaners. If skinned over, break film with a dry cloth to remove as much as possible

2. Clean hands with a dry cloth.

Products shall be ideally stored in a cool, dry location in unopened containers at a temperature between 8°C to 28°C (46°F to 82°F) unless otherwise labeled. Optimal storage is at the lower half of this temperature range. To prevent contamination of unused product, do not return any material to its original container.
