• Moistureresistant, Good thermal oxidation and chemical stability •Retains its grease like consistency from -55°C to +200°C
• Odourless
• Highly water repellent Adheresreadily to dry metals, ceramics, rubber, plastics and insulating resins

APPLICATIONS

• Amoistureproof seal for aircraft, automotive and marine ignition systems and spark plug connections, disconnection junctions in electrical wiring systems also in electrical assemblies and terminals.
• Used as a seal and lubricant for cable connectors,battery terminals, rubber door seals, switches and rubber and plastic O-rings and as a assembly lubricant for various metal-on-plastic and metal-on-rubber combinations.

TYPICAL PROPERTIES

1. Themaximum temperaturelimit may approach 260°C with no oxygen present.

HOW TO USE

JOMG 2953 can be applied by hand, specially designed automated equipment, brushing or wiping. Certain designs of grease guns may seize up with silicone compounds; test prior to use. A thinner consistency can be achieved by dispersing in solvents such as xylene, mineral spirits and methyl ethyl ketone.

JOMG 2953 can then be applied by brushing, dipping or spraying. JOMG 2953 should not be applied to any surface which will be painted or finished.

Such coatings may not adhere to the silicone-treated surface. If contaminated by a silicone coating, parts can be wiped

or washed with solvent, washed with detergent, or immersed in an alcoholic potassium hydroxide solution and then rinsed in clear water before painting.

Dispensing

Separation and compaction can occur with some high pressure dispensing equipment. This should be considered when designing dispensing systems for use with JOMG 2953 .

For information on appropriate dispensing equipment for your application, please contact JOME.

Solubility

JOMG 2953 is insoluble in water, methanol, ethanol or mineral oil and is soluble in mineral spirit and methyl ethyl ketone.  The suitability of a particular solvent should be based on testing prior to use. Flammability and toxicological properties should be important considerations in the choice of solvent.

Dimethyl silicone compounds should not be applied to O rings or other components made of silicone rubber because they will destroy the silicone rubber.

These compounds will also slightly swell natural butyl rubbers.

Chemical resistance

JOMG 2953 is not greatly affected by mineral oils, vegetable oils or air. It is generally resistant to dilute acids and alkalines, and to most aqueous solutions.

As each application may vary in chemical composition, pressure, flow velocity, relubrication requirements and equipment design, it is recommended that JOMG 2953 be tested before adopting for regular use.

JOMG 2953 is  not  intended  to  be  used  with  liquid  oxygen  and  should  not  be  used  in  applications  requiring  LOX compatibility without thorough testing for the specific application.

HANDLING PRECAUTIONS

When using solvents avoid heat, sparks and open flame. Always provide adequate ventilation. Obtain and follow handling precautions from the solvent supplier.
