Case Study: Sunroof Lubrication with Molykote

The Client

A market-leading automotive manufacturer was looking for a lubricating solution for their sunroof systems.

White lithium greases commonly used for sunroof applications did not match the specifications of the manufacturer, leading to a demand for a new solution.

The Problem

The lubricating solution required was to match the following specifications:

  • Be applied to sliding surfaces under heavy loads.
  • Provide a consistently-low coefficient of friction.
  • Perform as intended at low temperatures.
  • Exhibit a clean appearance.
  • Reduce noise and vibrations when opening and closing the sunroof.
  • Improve the safety of vehicle occupants.
  • Provide compatibility with plastic materials.
  • Be flexible for larger and more complex sunroof designs.
  • Improve durability for longer service life.

The Solution

Molykote experts worked with the automotive manufacturer to determine Molykote G-1033 as the ideal solution for this application. This lubricant was created using the original Molykote PAO formula as a base, maximising functionality and compatibility with sunroof systems.

Molykote G-1033 is a PAO grease with excellent lubricity and noise-damping properties. It provides compatibility with plastics – including fibre-reinforced plastics – and metals. It provides a wide operating temperature range and low friction. This lubricant has effectively been used in the industrial assembly of slides for automotive parts.

The Benefits

Through using Molykote G-1033, the automotive manufacturer was able to achieve:

  • Superior lubrication – leading to reduced wear and noise-dampening capabilities.
  • Excellent comfort for driver and passengers – reduced vibrations, noise and judder during sunroof operation.
  • High-performance from -45°C to 120°C – consistent and reliable at various temperatures.
  • Lightweighting – less friction on different substrates used in the sunroof.
  • Improved cleanliness – low oil build-up and bleed.
  • Improved safety – faster opening of the sunroof in response to potential obstructions.
  • Extended durability – resistance to corrosion, water-washout and evaporation.
