ADVERSE EFFECTS OF SOLID FILM & ESTER BASED LUBRICANTS
What are solid film lubricants?
Metal surfaces are characterized by series of peaks and valleys (under microscope), no matter how fine they are machined. Those uneven surfaces will lead to boundary lubrication state under high loads or low speed operations especially during cold-start, start-up, shut-down and severe metal contact applications. Nowadays, the only way for most of the lubricant companies to reduce the problems is to add one (or more) solid additive(s) into the lubricants due to the limitations of their technologies.
Most of the solid additives have layered platelet structure enable them to function. They are being smashed and crashed into micronic and sub-micronic sized particles that hope to increase the smoothness of the metal surface and the increase the contact area, and aimed to reduce the surface pressure. Most of the lubricant companies tell users that the adhesive wear of metal surface can be reduced. However, they never let people know the severe side effects of those solid additives.
What Is Esters (Dimethyl ester, Linear alkyl esters etc)?
Esters, under the Yellow List of Prohibited and Restricted substances by Cummins is announced on 06/2015 Toxic for reproduction, whether synthetic or bio-based, are constructed from acids and alcohols, and are subject to hydrolysis which breaks the ester back to acids and alcohols. The acids liberated, though are weak organic fatty acids, can do damage to the engine when present in doses over 0.1%, i.e. double and triple ester motor oil may contain esters up to 30%. The most common downsides and concern of esters when formulating with ester base stocks is compatibility with the elastomer material used in the seals. Another potential disadvantage with esters is their ability to react with water or hydrolyze under certain conditions. Generally this hydrolysis reaction requires the presence of water and heat with a relatively strong acid or base to catalyze the reaction. After prolonged use of ester based lubricant oil the surface of the metal parts inside the machine may erode and a polymer like film may be formed with other chemicals which will cause an irreversible damage to the system.

The ABF Technology Is The Only Solution
Steel Shield Lubricants with ABF Technology contain NO solid additives. This technology is the latest and the most advanced solution for any metal-to-metal lubrication in the world. It does not cause any damage or side effects to metal or machine systems. Also, ABF Technology helps you to cut huge amount of maintenance and energy costs with the minimum metal frictions and wears. It is the latest trend to replace any solid additives.
