The benefits to a Multi-Functional Surface is derived by the sum of all the coating property values, hence the name SIGMAtek. In addition, this term marks the adhesion mechanism used by MFStek in nano-scale coating materials utilized due to the fact that the sigma bond is that strongest known form of covalent bond, for optimal surface adhesion and coating durability.

In most applications, Multi-Functional Surfaces are made to create an easy-to-clean surface by forming a flexible and breathable nano-layer over the substrate, measuring approximately 1/500th the thickness of a human hair. This organic/inorganic compound creates an ultra-thin layer that becomes one with the surface on a sub-microscopic level. Each individual pore and crevasse is contoured, drastically reducing surface free energy while altering the substrates polarity. In turn, this creates a non-stick and easy to clean surface, virtually eliminating the need for aggressive chemicals and scrubbing. These effects allow the refined surface to be easily cleaned, using only water or pH neutral cleaner and a microfiber cloth, while visually maintaining a new and pristine appearance.

Multi-Functional Surfaces are most frequently produced in order to render substrates hydrophobic, oleophobic, and lipophobic (rejecting penetration of liquids, oils, fats, greases and dirt) which can be confirmed by an increased contact angle, the point at which a test liquid droplet meets the substrate. Surfaces are said to be hydrophobic when a contact angle equal to or greater than 90 degrees is observed. This point is critical to application as it is impossible to apply the product in such a way that one attribute of the technology works and not another. Therefore, the increase in contact angle confirm that presence of a functioning layer and its various multi-functional properties.

Upon request these layers can be rendered antimicrobial, effectively eliminating bacteria and viruses that come into contact with the surface. These long lasting effects maintain their effectiveness as long as the ultra-thin layer remains present, varying from 10 days to 10 years depending on the project and variant selected.
