NEOLUBE NO. 1 LUBRICANT - COLLOIDAL GRAPHITE IN ISOPROPANOL
APPLICATION: NUCLEAR POWER GENERATING PLANTS, NUCLEAR REACTORS, COMMERCIAL AND NAVAL
Neolube No. 1 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.
The composition of this material is 99% pure furnace graphite particles, a thermoplastic resin and isopropanol. The material has excellent radiation resistance and high chemical purity. The thin, non corrosive film of Neolube No. 1 prevents seizing, fretting, galling and resists abrasion. It is easy to apply by spray, dip or brush and has excellent adhesion after a fast air dry. The dry film of Neolube No. 1 will not migrate and it is non freezable.
Neolube No. 1 has satisfied the stringent requirements for lubricating the internal and auxiliary equipment mechanisms of commercial and naval nuclear reactor systems. Neolube No. 1 allows easy assembly, trouble-free operation and non destructive disassembly. Neolube No. 1 provides non corrosive, dry adherent lubrication for metal parts with limited clearances in applications were control of impurities is required.
Neolube No. 1 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.
A Certificate of Quality Conformance and Analysis is available for each lot upon request.
Neolube No. 1 has been used successfully in applications where it has withstood radiation levels of 1 x (10)9 rads.

Film Properties (regular & irregular surfaces):
The coated surface will be dry and will not become exposed when subjected to light abrasion.
Film continuity will not be broken, and metal surfaces will not be exposed.
Characteristic of isopropanol, no odor of halogenated solvents will be detected.
Mercury: Instruments and equipment containing mercury or compounds of mercury were not used in the manufacture and packaging of the lubricant, nor in testing and inspection, unless samples were discarded after the test. During the manufacturing processes, tests, and inspection, Neolube No. 1 did not come in contact with mercury or any of its compounds nor any mercury-containing devices employing a single boundary of containment. Compounds containing boron were not used in cleaning, processing equipment, or containers.
There is no intentional addition of low melting point metals such as lead, bismuth, zinc, mercury antimony, cadmium, tin, silicon, gallium, indium or arsenic to this product; nor of copper or silver.

Neolube No. 1, is supplied in a ready-for-use form conforming to the requirements of MIL-L-24131C. If further dilution is required by the application, add isopropanol while stirring thoroughly.
Substrates should be clean and dry before application. A solvent wipe and air dry is usually sufficient. For critical applications requiring maximum adhesion, the following pretreatment is recommended:
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.
NOT RECOMMENDED FOR USE IN OXYGEN SYSTEMS
Shake or agitate well before using. Apply with the brush in cap applicator or by conventional spray, brush or dip methods.
Material dries in approximately five minutes to the touch depending on temperature and humidity. Full cure properties up to two hours depending on thickness, temperature and humidity.
Neolube No. 1 is packaged in 2 ounce and 8 ounce non halogenated plastic bottles with a brush in cap applicator.
