ROYCO 1MS is a blend of lubrication grade micro fine powdered molybdenum disulfide that conforms to Mil-M- 7866, and technical grade petrolatum conforming to VV-P-236.
This compound is non-abrasive, highly shear stable, and has a relatively low volatility compared to some thread compounds.
Applications:
ROYCO 1MS is particularly suitable for use on aircraft engine spark plugs and threaded fasteners and fittings at temperatures below 800°F.
At higher temperatures, compound conforming to Mil-T-5544 (ROYCO 44) should be used in lieu of ROYCO 1MS.
Since this material is an electrical conductor, it is especially suited for anti-seize applications where the thread compound will not impede the flow an electrical current.
Advantages:
Electrical Conducter
Excellent shear stability
Superior anti-seize ability
Low volatility
Compatibility:
ROYCO 1MS is an electrically conductive thread compound and should be used with discretion in or near electrical equipment.
It is not a sealing compound and should not be used in oxygen systems.
Approvals:
ROYCO 1MS meets all requirements and is qualified to the current revision level of US MIL-SPEC: MIL-PRF- 83483.
