Understanding the Chemistry Behind Penetrating Oils
Penetration Power
Penetrating oils consist of a combination of solvents, lubricants, and surfactants. The solvents, such as mineral spirits or kerosene, work to dissolve rust and corrosion, while the lubricants, such as mineral oil or silicone, provide a slippery surface for the oil to penetrate further into the seized parts. Surfactants, such as detergents or wetting agents, help reduce the surface tension of the oil, allowing it to spread more easily over the metal surfaces.
The combination of these three components gives penetrating oils their ability to penetrate deep into seized parts and loosen frozen connections. The solvents dissolve the rust and corrosion, the lubricants provide a slippery surface for the oil to spread, and the surfactants ensure that the oil spreads evenly over the metal surfaces. This allows the oil to reach the deepest parts of the seized connection and break down the bond between the two metal surfaces.
Different Types of Penetrating Oils
There are several different types of penetrating oils available on the market, each with its own unique blend of solvents, lubricants, and surfactants. Some of the most common types of penetrating oils include:
| Type of Oil | Solvents | Lubricants | Surfactants |
|---|---|---|---|
| Mineral oil-based | Mineral spirits, kerosene | Mineral oil | Detergents, wetting agents |
| Silicone-based | Silicone | Silicone oil | Detergents, wetting agents |
| Petroleum-based | Petroleum distillates | Petroleum oils | Detergents, wetting agents |
The type of penetrating oil you choose will depend on the specific application. For example, mineral oil-based penetrating oils are good for general use, while silicone-based penetrating oils are better for use on electrical connections. Petroleum-based penetrating oils are the most powerful, but they can also be more harmful to the environment.
