Archoil AR9100 Nanobased Oil Additive in short:

AR9100 originates from Archoil’s patent, Potassium Nanoborate lubrication technology. Especially this nanobased oil additive dramatically reduces operating friction and protects equipment from wear.  Consequently, oil samples show extension of operating life and reduction of energy consumption.

Boron lubrication technology development comes from the Argonne National Laboratory for the US Dept. of Energy. Representing a ground breaking advance in lubrication technology, boron demonstrates great enhancement of lubricity and protection through the formation of a nearly frictionless solid boundary layer IN metal surfaces. A nanobased oil additive was born.

Since 1990, when Dr. Ali Erdemir discovered that boron was the one of the lowest coefficient of friction elements, particularly tribologists have recognized the tremendous advancement boron lubricants represented. Years of research and practical experience in maritime environments, Archoil’s Potassium Nanoborate formulation at this point represents the latest generation in boron tribology. At this point, another huge leap forward in lubrication came with its ability to reduce boron size down to the high efficient nano quantum effect level, and deliver it in a naturally occurring fatty acid ester matrix carrier, hence a nanobased oil additive.

AR9100’s proprietary ester carrier is specially formulated to facilitate the migration of the protective boron nanoparticles to surface metal. As AR9100 bonds chemically in the metal  through a chelation process it will bring performance for a much longer period of time compared to conventional, mechanically sticking lubricants.  Archoil AR9100 does not build up on metals, it bonds into the metal surface.


Firstly, the layer of nano boron particles bonds. Hence, it always prevents metal-to-metal contact, even when machines have not been running for a very long time. Also, the nanobased oil additive reduces the coefficient of friction of metal surfaces to below 0,037%, an extremely low value, thus reducing wear and heat to a minimum possible.

Secondly, the bonding layer is extremely robust and durable. It cannot flush away just like that. Another key point, it is resistant to extremely high pressures (>10.000 bar) and resistant to extreme temperatures up to 1.800 °C. At this point, it is still providing protection where conventional lubricants are long gone. The nanoborate layer in the metal protects actively against corrosion and pitting from acidic influences. These characteristics make that oil drain intervals can improve up to factor 6.

Thirdly, Archoil AR9100 oil additive aims for extreme friction reduction and corrosion protection in the heaviest marine environments. Still, nanoborate does not contain toxic or hazardous additives, as present in conventional high-performance lubricants. It is free of heavy metals, PTFE, molybdenum, graphite, boric acid, zinc, barium and lead. In any event, marine industrial quality.

Obviously, using Archoil AR9100 will maintain a high and usable quality of your engine, thruster and gear oil, for main engines as well as auxiliaries. Most additives used in conventional lubricants only start to work from temperatures of 20 °C and higher and drip off metals after 24 hours after machine-stop. The bonded Potassium Nanoborate is always there and works immediately.  Because hot-spots in de machinery are benefiting from nanoborate , oxidation of the lubricant and wear of the parts is downplayed to a minimum.
