Application Bulletin: Anti-wear alternative for synthetic Automatic Transmission Fluid

Ultrium™ 6700 - a Zero-SAPS, Ashless Multi-functional Technology as primary anti-wear additive

Ashless anti-wear additives are gaining increasing popularity primarily to address key functional properties of multi-speed Transmission Fluid (ATF) in preventing metal-to-metal contact, protection against corrosion, minimizing high temperature deposit formation and ensuring cleaner clutch engagement leading to superior friction control in demanding transmission applications.

Traditional anti-wear additives based on phosphorus ester chemistry, while highly effective in boundary lubrication regimes, present challenges due to their thermal instability, deposit formation, degrading shift quality, and environmental debits from elevated SAPS content. This necessitates the development of innovative additive chemistries that maintain wear protection in modern transmission hardware without compromising gear / bearing corrosion, additive degradation, and ensuring smooth clutch engagement.

Ultrium Technology in Action Aurorium Ultrium® 6700 is a high-performance, multifunctional polyester-based additive designed to address the complex demands of modern automatic transmission fluid formulations. Its advanced molecular architecture delivers enhanced oxidative stability, superior film formation, and optimized frictional properties across a broad temperature range. Ultrium 6700 supports extended fluid life, improved clutch durability, and compatibility with a wide range of base oils and additive systems, making it a versatile solution for next-generation ATF development.

Key Features of Ultrium 6700 Additive Solution in Transmission Oil:
