A transformer oil basestock is disclosed that includes at least 99 wt % of naphthenes and paraffins, based on the total weight of the transformer oil basestock, wherein the weight ratio of naphthenes to paraffins is at least 1, as measured by GC-MS, and wherein the paraffins consist essentially of isoparaffins, as determined by GC-FID. In addition, a transformer oil composition is disclosed that includes the transformer oil basestock, an anti-gassing agent and an antioxidant.

A lubricant formulation for an electric or hybrid vehicle includes a base oil, or a blend thereof, one or more additives, and a molybdenum amine complex, such as diisotridecylamine molybdate, are provided. Lubricant formulations can be characterized by one of: improving electric motor protection when a voltage is applied to an electrode in the presence of a formulation comprising the diisotridecylamine molybdate additive as compared to a fluid lacking the diisotridecylamine molybdate additive; maintaining the electrical resistance slope of a formulation comprising the diisotridecylamine molybdate additive as compared to a fluid lacking the diisotridecylamine molybdate additive; the formulation forming a protective film on copper surfaces; a change in color of the formulation indicating contact load, temperature, time, or viscosity change.

A silicone composition having an electromagnetic wave absorbing property and thermal conductivity includes liquid silicone; a high-specific-gravity soft magnetic filler having a specific gravity of 4.5 or greater; an intermediate-specific-gravity thermally conductive filler having a specific gravity of 4.0 or less; and a non-liquid anti-thickening and anti-settling agent. Furthermore, a curable grease is a two-component curable grease including a combination of a base compound and a curing agent that are used by being mixed together when used, the curable grease being to be cured by mixing of the base compound with the curing agent. The base compound is a silicone composition of the present invention, in which the liquid silicone is an organopolysiloxane having a vinyl group at an end thereof. The curing agent is a silicone composition of the present invention, in which the liquid silicone is an organohydrogenpolysiloxane.

A water-based lubricating grease composition includes at least 40 wt % water; a salt-based thickener; a polymer-based thickener; and optionally, an inorganic solid-based thickener. A process for preparing the water-based lubricating grease composition may include blending a suitable amount of water with a salt-based thickener to provide a thickened water-based grease, wherein the salt-based thickener is obtained from contacting a base with a fat; and adding a polymer-based thickener to the thickened water-based grease.
