Like all industrial chemicals, proper handling of Lubrizol 7067C ensures safety and performance longevity.

Safety & Toxicity:

Compatibility:

You will typically find Lubrizol 7067C in action in three specific applications:

While primarily industrial, some formulators use lower treat rates of 7067C to meet API GL-4 or GL-5 specifications for spiral bevel and hypoid axles. However, formulators must verify copper corrosion compatibility, as high treat rates can be aggressive to yellow metals (bronze, brass synchronizers).

To truly understand the value of this additive, one must understand the problem it solves. All lubricants thin out as they heat up and thicken as they cool down. The rate at which this happens is defined by the Viscosity Index (VI).

The Role of the Viscosity Modifier: Lubrizol 7067C consists of long, coiled polymer chains. At low temperatures (cold starts), these chains remain tightly coiled, contributing little to the fluid's internal resistance. As the temperature rises, the polymer chains expand and uncoil. This expansion pushes against the flow of the oil, counteracting the natural thinning effect of the base fluid.

The Role of the Pour Point Depressant: Simultaneously, the PPD component inhibits the formation of wax crystals in the base oil. When a lubricant gets very cold, wax molecules can interlock, turning the fluid into a solid gel. Lubrizol 7067C modifies the crystal growth, allowing the oil to remain fluid at much lower temperatures.
