New and patented Boron CLS Bond is a biodegradable lubrication technology designed for the latest mechanical advances in precision engineering. The technology platform – using boric acid as a solid boundary layer, extreme-pressure additive – was originally discovered and patented by the U.S. Department of Energy’s Argonne National Laboratory of Argonne, Ill., operated by the University of Chicago. In 1991, it was awarded the prestigious R&D 100 award for what has become the Boron CLS Bond technology.


Boron CLS Bond technology is based on using crystalline boric acid platelets as a solid boundary-layer component, which is synergistic with the hydraulic (fluid) lubricant delivery and/or dispersal vehicle. In the presence of oxygen and moisture, boric acid reacts with metal via covalent bonds to form approximately a 20-nanometer surface of metallic boric oxide in the presence of oxygen and then spontaneously produces more boric acid, the molecules of which macromolecular bond together to form a crystalline lattice of platelets. The boundary layer of platelets is approximately 200 to 400 nanometers thick. These platelets align themselves parallel to the metal surface and conform to the direction of movement – like a loosely dispersed deck of playing cards.


Each Boron CLS Bond platelet has strong macromolecular bonding giving it the equivalent of 85 percent hardness of diamonds. Only weak Van der Waals forces attract the platelets to each other, allowing virtually frictionless platelet to platelet interaction. This translates to extremely low-friction coefficient (under 0.01 percent) between the platelets and the metal surfaces they separate.


Minute amounts of residual boric acid in the presence of moisture and oxygen cause any sheared platelets to be rapidly replaced in a self-renewing cycle of boric acid-metal-metallic boric oxide-crystalline boric acid platelet regeneration and bonding, thus a self-replenishing lubricant.


Product and application specific solutions have been tested extensively in independent laboratories, universities, research centers and in the field worldwide. The benefits of Boron CLS Bond products have been documented in test after test.


Dramatically Reduces Friction and Wear

Once established on the metal surfaces, Boron CLS Bond outperforms all other fluid or fluid-dispersed extreme-pressure or friction-reduction additives. When Boron CLS Bond chemically bonds with the metal, the resultant boundary layer virtually eliminates metal to metal contact. The boric acid platelets reduce friction 80 percent and wear 90 percent.



Boron CLS Bond contains no toxic additives. Boron as one of the elements that make up the planet (combines with oxygen and other elements to form boric acid) is 100 percent biodegradable, ubiquitous in nature, and fundamental to life. Boron CLS Bond products go beyond the commonly required government standards and mandates worldwide. The technology can be used to replace all toxic extreme-pressure additives found in lubricants today such as sulfur/ZDDP, chlorinated paraffin’s, molybdenum, graphite, etc.


Eliminates Corrosion and Micropitting

Boron CLS Bond is anti-corrosive, creating a metallic Boric Oxide coating that seals out moisture, acids and oxygen, resulting in the elimination of corrosion and micropitting. The boric acid (PH 5.73) acts as a buffer to dilute or neutralize strong acids and bases, delaying lubricant oxidation.


Protects Metal Surfaces from Deposit Formation, Removes Sludge and Varnish, and Prevents Oxidation

With heat, pressure and time, boric acid’s chemical affinity for metal will allow it to displace other metal surface coatings such as sludge, varnish, carbon deposits and metallic oxides (e.g., ferrous or aluminum oxides). Once displaced, these contaminants can be removed by filtration or by draining and replacing the fluid lubricant. The newly leaned metal surfaces are sealed by metallic boric oxide, and thus metal or contaminant catalyzed hydrocarbon (oil) oxidation is prevented and the useful life of the fluid lubricant is extended at least two times.


Self-Renewing, Long-Life Lubrication Solution

Utilizing minute amounts of residual boric acid in the presence of moisture and oxygen, any sheared platelets are rapidly replaced in a self-renewing cycle of solid lubricant to metal surface regeneration and bonding. This translates into longer relubrication and service intervals because the metallic boric oxide forms a covalent bond with the metal. The Boron CLS Bond boundary layer is virtually permanent and retained even in the absence of or loss of the fluid lubricant (oil). The Boron CLS Bond boundary layer is not removed or depleted even after fluid drains.


Versatile and Compatible

You can use Boron CLS Bond to enhance any of your existing lubrication solutions or a custom solution can be created for your unique needs. Custom products often allow a single Boron CLS Bond technology to replace several different lubricant products used in a plant or manufacturing process. The Boron CLS Bond technology is compatible with most commonly known fluids, base oils and greases. It has been and is being used in virtually all lubrication regimes.


Contributes to the Bottom Line

Boron CLS Bond reduces the total cost of operating and maintaining fluid systems. It maintains the quality and extends the longevity of the base lubricants while offering the greatest protection against friction and wear, resulting in:

1.      Decreased fuel and energy consumption

2.      Increased productivity

3.      Increased efficiency and uptime

4.      Reduced repair and warranty expenses

5.      Reduced maintenance expenses
