Product description:
Permatex Ultra Copper 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. Permatex? Ultra Copper? is the most advanced high performance, high temperature (up to 700°F intermittent) RTV gasket available.

Directions for use:
For assembly as form-in-place gasket
1. Remove all previous material from mating surfaces. Permatex? Silicone Stripper or 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. 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, first tracing the internal areas of the gasket configuration, then all surrounding bolt holes as shown below:
6. Assemble parts immediately while silicone is still wet.
Secure or tighten to recommended torque specs.
7. Re-torque will not be necessary after the product has cured.
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 silicone 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.
