Viscosity Modifier
Description
Petadd VM-35(C) is a solid and highly stable pellet-form viscosity modifier, based on olefin copolymer chemistry. It is intended for use in high quality automotive crank case lubricants.
Petadd VM-35(C) has a narrow molecular weight distribution. Offering excellent low temperature properties and shear stability, this product is suitable for a wide range of demanding applications.
Application
- Petadd VM-35(C) should be dissolved under high agitation in oil at 100°C to 120°C for 6-to-12 hours, until all solids have been dissolved.
- Dependant on the viscosity grade required, and the base oil used, a recommended treat rate is 0.8-1.2% in the finished lubricant.
- Used with a suitable PPD.
Storage and Handling
Petadd VM-35(C) should not be stored at temperatures >30°C for prolonged periods. Avoid direct sunlight. When handling, wear suitable dust masks and gloves.
