MOLYKOTE® SK-623 Grease

Superior Noise Reduction and Vibration Damping

White solid lubricant formulation dampens mechanical vibrations and prevents stick-slip motion in plastic gear assemblies, eliminating the squeaks, rattles, and buzzing sounds that generate customer complaints and costly warranty claims in automotive interior applications.

Wide Temperature Range Performance

Maintains consistent noise reduction effectiveness and lubrication from -40°C to 150°C, ensuring quiet operation during cold-start conditions and sustained performance in high-temperature underhood and sunlight-exposed interior applications throughout vehicle lifetime.

Excellent Plastic and Rubber Compatibility

PAO synthetic base chemistry does not attack engineering plastics, elastomers, or interior fabrics commonly used in automotive assemblies, preventing material degradation, discoloration, and component failure while ensuring lifetime lubrication performance.

White Color for Interior Applications

Non-staining white appearance eliminates aesthetic concerns when grease migrates onto visible interior trim surfaces, door panels, or fabric components, maintaining premium vehicle appearance and perceived quality throughout ownership.

Stick-Slip Prevention

Advanced friction modifier additives eliminate the stick-slip phenomenon that causes jerky motion and squeaking sounds in slowly moving mechanisms like seat adjusters, allowing smooth, consistent operation that enhances customer perception of build quality.

**Long-Term Lubrication Stability
Superior oxidation resistance and minimal oil separation ensure consistent noise reduction performance throughout 12-15 year vehicle service life, eliminating the need for maintenance and reducing total cost of ownership.

Interior Trim Squeaks and Rattles (BSR Issues)

Eliminates the squeaking, creaking, and rattling noises from door panels, center consoles, armrests, and trim assemblies caused by plastic-on-plastic friction and vibration transmission, preventing the warranty claims and customer dissatisfaction that damage brand reputation and residual value.

Windshield Wiper Motor Noise and Jerky Operation

Prevents the grinding, buzzing, and stick-slip motion in wiper transmission plastic gears that create audible noise during wiper operation, ensuring smooth, quiet performance that maintains driver visibility without generating distracting mechanical sounds.

Power Window Regulator Squeaking and Binding

Eliminates the squeaking and jerky motion in window lift mechanisms caused by dry plastic guides and metal-on-plastic friction, ensuring smooth one-touch operation without the annoying sounds that prompt dealer service visits and negative customer feedback.

Seat Adjustment Mechanism Noise

Prevents the clicking, rattling, and grinding sounds from power seat adjustment motors and plastic gear trains that occur during seat positioning, maintaining the premium quiet operation expected in modern vehicles and preventing the perception of poor build quality.
