Customer

A market-leading Tier 1 automotive supplier with extensive global design, engineering and manufacturing capabilities produces innovative sliding sunroofs and panoramic roofs for many OEM brands, meeting requirements to maximize value-added comfort, convenience and safety.

Challenge

To meet performance specifications of many global and regional vehicle OEM customers, this Tier 1 supplier needed an effective, application-matched lubricant that outperformed available options at low temperatures and ensured safer and more reliable opening and closing of its sliding-roof designs.

Solution

Translucent MOLYKOTE® PAO lubricant resists dirt buildup to provide added cleanliness and extended service life on sliding-roof guides.

The sunroof manufacturer collaborated with MOLYKOTE® – and the brand’s trusted expertise, problem-solving capabilities and broad technical support – to develop an advanced specialty PAO lubricant for use on sliding-roof guides to ensure smooth, reliable and quiet operation across a wide temperature range.

The opportunity

In developing early designs of tilt-up and sliding sunroofs for its home market and possible export, this automotive component manufacturer demonstrated a strong commitment to ensuring the highest-quality technology. White lithium greases were well-known, trusted and relatively economical lubricants for applications with sliding surfaces under heavy loads. However, none of the available options exactly met all of the performance specifications set by the sunroof design and engineering teams.

Trust in the MOLYKOTE® brand – and our specialty lubrication expertise, problem-solving capabilities for specific applications, broad technical support and ability to meet global supply requirements – led this global Tier 1 supplier to seek our help.

The Sunroof Guide Lubrication Challenge

An application-matched lubrication technology that could deliver consistently low friction was needed to ensure proper opening and closing forces across a range of sliding-roof designs. Low-temperature performance was a critical design parameter. And other key requirements added to the development challenge: The Smart LubricationTM solution also needed to address priorities such as a clean appearance, reduced noise, safety for vehicle occupants, compatibility with plastic materials, durability for extended service, and design flexibility for larger and more complex sliding roofs in the future.

Close collaboration between the sunroof design engineers and MOLYKOTE® application engineering and technical support (AETS) specialists – in our development and testing labs as well as in sunroof production plants for different markets – was essential.

The solution about Sunroof Guide Lubrication

The specific MOLYKOTE® PAO grease first developed for basic sunroof designs has grown in step with the manufacturer. Starting in the manufacturer’s home market and then expanding into other geographies, this MOLYKOTE® brand Smart LubricationTM solution is now maximizing functionality and comfort in all types of sunroofs, including popular panoramic roofs.

For more than two decades, as sliding roofs became an integral part of today’s vehicles in many regions, the MOLYKOTE® synthetic PAO lubricant has delivered key advantages and benefits:

  • Superior performance with excellent lubrication and noise-damping capabilities
  • Enhanced comfort with reduced noise, judder and vibration during sliding-roof opening and closing
  • Consistent smoothness and reliability at temperatures from -45°C to 120°C (-49°F to 248°F)
  • Increased safety by promoting a faster response to potential obstructions
  • Good lightweighting potential with less friction and wear on different metals and resins
  • Added cleanliness with low bleed, less oil separation and resistance to dirt buildup
  • Extended service life with resistance to water washout, evaporation and corrosion

The same key advantages and benefits are available in MOLYKOTE®  Grease, a specialty PAO lubricant for sliding-roof designs manufactured in North America.
