                    TECHNICAL INFORMATION SHEET

          NEOLUBE NO. 2 LUBRICANT - COLLOIDAL GRAPHITE IN ISOPROPANOL

            HIGH CHEMICAL PURITY $ LOW HALOGEN CONTENT $ DRY FILM LUBRICANT $ NUCLEAR GRADE

                                          

NEOLUBE NO. 2  is a compound of processed micrographite and thermoplastic resin in isopropyl alcohol.   Applied by brush, spray or dipping, it dries in seconds to a slippery, lustrous, adherent film of purest graphite.  NEOLUBE NO.  2 is a dry film conductive lubricant used extensively at nuclear power generating plants and other nuclear facilities as an anti-seize compound, thread lubricant and for lubricating moving parts and rubbing surfaces. 

 

This material has the properties that enable it to be used for lubrication in internal and external applications of commercial and government nuclear reactor systems.  High grade graphite particles in thermoplastic resin and isopropanol produces a thin, non-corrosive film.  NEOLUBE NO. 2  resists abrasion and lubricates threaded parts, moving parts and rubbing surfaces.  This material allows easier assembly and nondestructive disassembly. 

 

The composition of this product is 99% pure furnace graphite particles in isopropanol.  The material has excellent radiation resistance and high chemical purity.  The thin, non-corrosive film of NEOLUBE NO. 2 prevents seizing, fretting, galling and resists abrasion.  It does not migrate and is non-freezable.  NEOLUBE NO. 2 provides a non-corrosive dry adherent lubrication for metal parts with limited clearances in applications where control of impurities is required.

 

NEOLUBE NO. 2 IS NOT RECOMMENDED FOR LUBRICATING THREADS IN THE REACTOR PRIMARY CONTAINMENT AREAS, WHERE OPERATING TEMPERATURES FOR THE FITTINGS ARE GREATER THAN 400°F.  NEOLUBE NO. 650 IS RECOMMENDED FOR USE IN CONTAINMENT AND/OR SECONDARY SIDE IN NUCLEAR APPLICATIONS.

 

Radiation:  NEOLUBE NO. 2  has been used successfully in applications where it has withstood radiation levels of 1 x 10⁹ Rads.

 

Mercury Certification:  Instruments and equipment containing Mercury or compounds of Mercury are not used in the manufacture and packaging of NEOLUBE NO. 2, nor in testing or inspection, unless samples are discarded after tests.  Compounds containing Boron are not used in cleaning, nor processing equipment, nor containers.  There is no intentional addition of low melting point metals (Lead, Bismuth, Zinc, Mercury, Antimony, Cadmium or Tin) to this product, nor of Copper or Silver.

                 PROVEN APPLICATIONS

 

Industrial applications of NEOLUBE NO. 2 include those where oils or greases, because of their very nature, are inadequate or objectionable.  Oils collect dust, burn off or congeal; drip, soil and insulate.  When used within load limits, NEOLUBE NO. 2  is an adequate substitute for oils or greases with none of their disadvantages.  (DO NOT USE NEOLUBE NO. 2 ON BALL OR ROLLER BEARINGS.) 

 

NEOLUBE NO. 2 has been used successfully on Zircon Fuel Rods surrounded by Uranium pellets.  During this application, it will not hinder the heat transfer of neutron flux. 

 

It has also been used successfully in vacuum systems.  Other proven applications include:

 

1. Non-seize lubricant for bolts-metals-valves.   Anti-seize lubricant for stainless steel bolts.

2. Lubrication coating that is dust free and clean for business machines, vending machines, clocks, locks, meter mechanisms, and piano and organ mechanisms (mating surfaces).

3. Lubricant for high pressure air fittings or hydraulic systems.

4. Lubricant for buss bars carrying contact shoes, high tension switch contacts. Reduces chatter, arcing and pitting.

5. Static bleeding of conveyor belts; lubricate conveyor chains in degreasing operations; reduce static on floors.

6. Excellent shielding properties for certain types of electric interference.  Prevents radio wave interference.  Maybe used in printed circuit techniques.  Maybe used for shielding tape recorder cases.

7. Coating for gaskets, grid coating for cathode ray tubes.

8. Cutting lubricant on difficult metal cutting jobs.

9. Ideal source for graphite films in nuclear applications.

10.           Ideal where a dry film lubricant prevents soiling as in:  knitting, weaving and lace making machines.

11.           Excellent for die and mold pretreatment conditioners.  Protects from atmospheric elements and aids in initial lubricant.

12.           Internal combustion engine components (assembly and break-in)

13.           Automotive and industrial gaskets.

14.           Rubber components (assembly and break-in)

15.           Opaque coating for film negatives.

                     DIRECTIONS

 

STIR WELL BEFORE USING.  Apply with a soft brush, dipping or spraying.  If a smudge free surface is desired, remove excess by polishing with a soft cloth when dry.  For heavy service, apply 2 or 3 coats.  NEOLUBE NO. 2 may be diluted 1:1 with Isopropanol for very light service.  Functional thickness on a surface is 0.3 - 0.6 mils in the dry state.

 

                        USAGE

 

Substrates should be clean and dry before application.  A solvent wipe and air dry is usually sufficient.  For critical applications requiring maximum adhesion, the recommend the following pretreatments:

 

Steel:        Degrease, sand or vapor blast and/or phosphate coat.

Aluminum:     Degrease, sand or vapor blast, degrease, meta etch or anodize.

Stainless Steel:     Degrease, sand or vapor blast and/or Granodine 16 (Amchem).

Copper Alloys:       Degrease, sand or vapor blast, degrease, dilute nitric acid dip and water rinse.

Rubber:       Clean with appropriate solvent.

Plastic:      Sand lightly, wipe with appropriate solvent.

 

                     APPLICATION

 

Shake or agitate well before using.  Apply with brush in bottle, spray, dip or use regular brush.

 

                      DILUTION

 

If the application requires further dilution, add isopropanol while stirring thoroughly.

 

                       CURING

 

The coating air dries to the touch in 5 minutes under normal conditions of temperature and humidity.  Full cure properties in approximately two hours depending on film thickness and drying  conditions.
