An innovative and pending patented technology (CA 2909198)

The A3S technology has been developed in order to eliminate any risks of bacterial and viral diseases spread through a pending patented (CA 2909198) biocidal effect treatment. We named this technology UmanProtek.

This technology is characterized by anodization of aluminium, which allows preparation of the surface for reception of the biocide treatment. The effectiveness of the biocidal agent’s active ingredients is thus combined with the mechanical resistance of anodized aluminum.

This ingenious combination makes UmanProtek technology an efficient, resistant, and versatile method for destroying infectious agents (A3S patent pending technology) (CA 2909198).

Anodization, a solution for your project!

The anodization process consists of building a controlled oxide layer on the aluminum surface. This provides an oxidation protection to the surface. We can produce three types of anodization under the standard MIL-A-8625F.

Sulfuric anodization

Such an anodization is produced by using a sulfuric acid electrolyte at a temperature between 17 and 21 Celsius degrees. This procedure provides the aluminum with an anodic layer thicker than the one generated by chromic anodization, which assures a better corrosion resistance.

Hard anodization

By plunging the aluminum in a sulfuric acid electrolyte at a low temperature with a tension and a density of high currents, we obtain an anodization called ‘’hard’’. As its name suggests, this procedure serves to increase the hardness, but also the abrasion resistance as well as the electric and thermal isolation of the aluminum.

Nosocomial infections: A truly menacing plague on a global scale!

A3S has a technology to eliminate risks of viral and bacterial diseases spread

This is an overview of the issue of the infections that have occurred in different Canada health establishments. It reflects the gravity of the situation and the urgency to act :

  • More than 200 000 Canadians catch an infection associated with health care (nosocomial infection).
  • 10 % of adult Canadians will get sick because of nosocomial infection.
  • 8 000 to 12 000 patients die each year because of nosocomial infection.
  • Cost per day for 1 infected person : 2 000 $ to 20 000 $.
  • Cost per year in Québec: 200 M$.

UmanProtek technology procedure

Preliminary preparation of the surface

Before proceeding with the adonization, the surface must be cleaned in order to get rid of its oils and greases. Then, it is deoxidized in order to remove the natural oxidation on the aluminum. Finally, a stripping of the aluminum is done by soaking in order to get a uniform surface decreased of its imperfections.



The procedure is to create pores whose quality is assured by the utilization of specifics anodization parameters. This step is done by the passage of current in an electrolyte.


Incorporation of antimicrobial substances

Antimicrobial substances are then bound to the nanostructured aluminum oxide surface formed during anodization (A3S pending patented technology)(CA 2909198).



Finally, by closely controlling surface sealing, we can ensure the endurance of our products over time.

UmanProtek technology advantages


Prevents bacterial and viral diseases spread by touch

The antimicrobial effect on treated surfaces prevents infectious diseases spread. Also, the antimicrobial treatment can be applied on multiple commercial, industrial or institutional surfaces. In fact, all surfaces touched by several individuals in a limited timeframe (door handles, plate, etc.) are excellent targets for A3S treatment. In its antimicrobial solution, A3S wants to reduce considerably microbes transmission between individuals.


Antimicrobial molecules which eliminate virus and bacteria

The antimicrobial molecules present in treated aluminum allow the elimination of 99,99% of bacterias in only a few seconds. The eradication of microorganisms on the treated surfaces eliminates different diseases spread problems that they cause via transmission vectors that you want to target (door handles, plates, handrails, brackets, toys, medical tools, etc.).


Proven and guarantee effectiveness

Given that the surface is deeply treated, the microbial effect assures you rugged durability. Furthermore, unlike competitors’ products, which are only bacteriostatic (prevent bacterial growth), A3S UmanProtek technology makes the products bactericidal. In other words, it completely eliminates viruses and bacterias.


Incredible quality-price ratio

In addition to helping your surfaces being self disinfecting, UmanProtek technology is offering an incredible quality-price ratio! As a matter of fact, its properties give you the opportunity to save a lot of money, especially in sterilization (cleaning products, cleaning time). Moreover, abrasion resistance treatment provides a superior useful lifetime.

Insight of the bactericidal fast effect in real situation

With the help of a luminometer, we conducted a quick test to check the bactericidal effect (bacterial elimination) on treated surfaces. This test is corroborated by a microbiological test that consists of seeding (with a 10 6 S. aureus solution) non treated and antimicrobial treated surfaces during 5 minutes and making a specimen collection which is spread out on agar. As we can see in the left portion of this figure, a few hundred unities formed a colony (UFC) on the non treated surfaces while no UFC has been detected on the antimicrobial treated surface.
