VNII NP-225 is a silicone fluid thickened with fine molybdenum disulfide; it contains a stabilizing additive.
VNII NP-225 is used for lubrication of threaded joints and heavy-duty slow-speed units within the temperature ranges from -60°C to +250°C (aluminum alloys), -60°C to +350°C (alloy steels) and -40°C to +300°C (slow-speed friction units).
