Introduction to anti-fingerprint stainless steel

Anti-fingerprint stainless steel is a coating treatment. And it originated in Japan.

In recent years, stainless steel has been required for the housing of home appliances. Moreover, this high-quality product with a metallic feel and robustness has become the main force.

However, it is easy for people to leave fingerprints on it when using it. For example, elevator panels, handrails, ovens, etc. And this greatly affects the aesthetics of the product. Moreover, fingerprints and cleaning agents may also corrode the surface of stainless steel.

And in order to prevent this, people have added a coating to protect the stainless steel.

Moreover, this coating will not affect the finish and other surface effects of stainless steel.

Generally speaking, people apply acrylic or urethane polymers on the surface of stainless steel. And this forms the coating.

In this way, people avoid fingerprints on stainless steel products.

Moreover, this makes it easy to clean.

Even better, it also enhances the corrosion resistance of stainless steel.

Meanwhile, this coating is transparent. Therefore, not only ordinary stainless steel, people can add this kind of coating on various surface treatments.

For example hairline stainless steel, mirror 8k stainless steel, titanium stainless steel, No. 4 stainless steel, embossed stainless steel etc.

What is anti-fingerprint stainless steel?

Before the invention of anti-fingerprint stainless steel, the use of stainless steel had some problems.

Problems we had

Anti-fingerprint stainless steel achieves the desired effect through its anti-fingerprint coating.

Generally, the greater the surface tension of metal, the easier it is to adhere to other objects.

The coating reduces the tension from the metal surface to the coating surface.

As you may know before, the surface of stainless steel is a very lively high free surface.

Moreover, it has strong wettability. Therefore, this leads to a color change when it comes in contact with water or other wetting substances.

Moreover, the highly reactive metal surface can produce strong chemical bonds.

Therefore, it is difficult for people to clean these fingerprints and oil stains.

Anti-fingerprint stainless steel

Later, people discover that builders containing polysilicates can soften hard water.

Moreover, it contributes to the detergent function of the surfactant.

Meanwhile, people use special metal catalyst synthesis methods to form builders.

Therefore, its hydrophilic and hydrophobic groups can form a coating on the surface of stainless steel at a ratio within a predetermined range.

In this way, by combining the characteristics of hydrophilic and hydrophobic groups, it can resist fingerprints.

Besides, the anti-fingerprint effect depends on the thickness of the coating.

And the thicker the coating, the better the anti-fingerprint effect of stainless steel.

However, a coating that is too thick will form orange skin-like particles on the surface of the stainless steel.

Thus, this affects the appearance of stainless steel. Especially stainless steel with surface treatment.

In addition, if its coating is too thick, when people are processing stainless steel, the coating may be broken due to bending.

Therefore, the thickness of the coating is 1-10 microns.

Moreover, the silica in the coating can change the original reflectivity and high scattering characteristics of stainless steel.

Besides, anti-fingerprint treatment does not mean that fingerprints will not be printed on the surface of stainless steel, but that the fingerprint marks on the coating are lighter than those on ordinary stainless steel.

Moreover, it is relatively easy for people to clean it without leaving stains.

Besides, it has passed the SGS test and the RoHS standard. Moreover, it meets European and American environmental protection requirements.

With this coating, people can also make the color of stainless steel into black and rose gold.

In addition, if necessary, people can make it into a customized color.

In addition to the original iron color of stainless steel, there are also fashionable black and rose gold.

The manufacturing process of anti-fingerprint stainless steel

First, people have to check the flatness of the stainless steel surface.

Then, people have to rinse for the first time to remove grease.

Polyol-based compounds react with isocyanates to form urethane polymers.

Moreover, people usually add enough catalyst and hardener during the reaction.

In addition, in order to enhance its high-temperature resistance and freezing resistance, people sometimes add acrylic acid.

Next, people melt the above-mentioned components in a solvent.

And this formed the cloth liquid.

Then, people apply it on the surface of stainless steel.

Next, people can dry it.

In the process of drying, it is easy for people to remove the coating process.

After that, the coating hardens. Moreover, the hardening process hardens the coating and also removes the solvent remaining during the drying process.

Then, people used epoxy or vinyl to soften the coating through polymer materials.

And this can prevent the coating from cracking when the stainless steel is bent.

As for its coloring treatment, compared with other pigments, the paint of the coating process is more expensive.

Moreover, this process also requires UV curing equipment.

In addition, the high-temperature heat generated by the ultraviolet lamp may distort the appearance of the product.

And it is difficult for people to prevent this thermal deformation.

Finally, people check the surface of the finished product, form-ability, and solvent resistance.

At this time, pay attention that the coating has no signs of damage, bubbles, cracks, peeling, or softening.

In this way, people have completed the production of anti-fingerprint stainless steel.

Then, people use PVC paint to pack it.

Next, let’s take a look at its features.

Features of anti-fingerprint stainless steel

Judging from the name, the surface of the anti-fingerprint coating will not stick fingerprints.

Similarly, stainless steel will be more resistant to stains.

However, in addition, anti-fingerprint stainless steel has many other properties:

Easy to clean the anti-fingerprint stainless steel

Moreover, it can keep the water on the surface in the shape of a droplet.

Therefore, scrubbing will not leave water stains.

In this way, cleaning the stainless steel surface is much easier.

Moreover, when cleaning, people can use a clean cotton towel or light detergent to scrub it.

In addition, after cleaning, there is no residue on the surface of the anti-fingerprint stainless steel.

Strong durability

The hardness of ordinary stainless steel is 2-H to 3-H. While the surface hardness of anti-fingerprint stainless steel is 2-3 times that of it.

And it can reach 6-H. Thus, this reduces the scratching of the surface by foreign objects.

Therefore, the anti-fingerprint coating provides extremely high abrasion resistance.

Meanwhile, this extends the life of stainless steel in harsh environments.

Furthermore, colloidal carbon dioxide silicon is widely distributed in the surface layer and coating of stainless steel.

And this can increase the durability of stainless steel. Therefore, compared with ordinary stainless steel, anti-fingerprint stainless steel has better durability.

Increased corrosion resistance

Since this coating provides a barrier for stainless steel, it can prevent the intrusion of oxygen and moisture.

And this increases the corrosion resistance of stainless steel.

Specifically, it can pass a 500-hour salt spray test.

And this means that it has almost permanent corrosion protection.

Variety of anti-fingerprint stainless steel

People can customize the colors according to their needs. However, its cost will be higher.

Moreover, the anti-fingerprint coating does not just provide a single surface effect.

Instead, one can do it on colored stainless steel. And on the basis of wire drawing, hairline, No.4, embossing, 8k mirror, titanium stainless steel, and other surfaces, people can achieve anti-fingerprint effects.

Laser-cut

People cannot use a laser to cut conventional stainless steel transparent coatings.

Moreover, the cutting process will leave obvious burn marks on the stainless steel surface.

However, the nano anti-fingerprint coating can reduce the laser burn marks.

Gentle process

One only needs to peel a few microns of stainless steel surface to remove rough areas.

Therefore, the anti-fingerprint treatment is gentle on stainless steel.

And this will not cause any microscopic structural changes.

Environmentally friendly anti-fingerprint stainless steel

The poly-silicate in the coating has good hard water softening ability and solubility.

Therefore, it is an environmentally friendly material that does not pollute water and the environment.

Moreover, it is non-toxic and mildew proof.

In general, the anti-fingerprint stainless steel coating effectively improves the performance of the stainless steel surface with little cost. Moreover, it can be used as a low-cost alternative to traditional protection procedures.

We mentioned above that there is diversity in anti-fingerprint stainless steel.

Next, let’s take a look at their specific classification.

Classification of anti-fingerprint stainless steel

There are three different anti-fingerprint stainless steel coatings:

Urethane polymer

One can react to polyol compounds with isocyanates. And this forms a urethane polymer.

Moreover, it has excellent wear resistance.

Therefore, it helps other chemical combinations of c=o in carbamate compounds.

Moreover, because of its strong heat resistance and three-position stability, the urethane polymer has good compressive strength.

In addition, it is not affected by temperature. Even in the cold winter, the temperature will not limit its effectiveness.

And polyurethane polymer also has elasticity, acid resistance, alkali resistance, chemical resistance, and UV resistance.

Acrylic paint

The acrylic paint contains 27.6%-36.2% polysilicate.

And it has 10.6% epoxy or vinyl resin.

Moreover, it contains less than 10.6% of free radicals.

These free radicals can be -OH, -NH2, and -COOH.

And they together form the first group of hydrophilic materials.

Furthermore, the second group of materials has additives containing -CnF2n+1.

In addition, there is -SiR3 in it.

Among them, CnF2n+1 and -SiRi3 are used as coatings, the first group of additives is used as hydrophilic bases, and the second group of materials is used as hydrophobic bases. Moreover, these additives can improve the stability of the anti-fingerprint coating.

In addition, people use AI203 or ZnO as a polishing inhibitor to control the gloss of the coating. Therefore, this can improve its optical characteristics.

As for its corrosion resistance, it can pass the hydrochloric acid mist test for more than 1000 hours.

In addition, the coating has a load of 750 grams and a hardness of 2H.

Because the chemical composition of sol-gel is similar to glass, it can maintain the cold metal texture of the substrate. Meanwhile, this improves the chemical resistance and mechanical properties of stainless steel.

For most sol-gel materials, people must cool and use them immediately after production.

However, some materials can have a shelf life of several months at room temperature. This way, people can store them.

Nano anti-fingerprint stainless steel

Nano coating is the best anti-fingerprint coating.

First, people add liquid to the film. Then, people have waited for plasma or excimer technology to cross-link them together.

In this way, the nano compound adheres to the surface of the stainless steel and forms a thin and strong anti-fingerprint coating.

Moreover, this coating prevents oxygen and moisture from contacting the stainless steel surface.

So, it greatly increases the corrosion resistance of stainless steel.

In the beginning, people used this technology in the aviation industry.

With the development of stainless steel, people also use it in the stainless steel industry.

Moreover, it can significantly improve the durability and life of stainless steel. In the long run, it also reduces maintenance costs.

And it has a load of 750 grams and a hardness of 6H.

Moreover, it can pass more than 1500 hours of the hydrochloric acid test.

As for its characteristics, it can maintain the original gloss and roughness of stainless steel.

And it is very suitable for rough surfaces made of metal or plastic.

Moreover, the coating is so thin that it is almost invisible.

However, it will be slightly darker than the unreleased stainless steel.

Scope of application

At present, anti-fingerprint stainless steel has become one of the most demanded coatings.

However, due to the high outdoor ultraviolet radiation, it is only suitable for indoor use.

For all indoor stainless steel products, such as refrigerators, ovens, range hoods, etc., people use anti-fingerprint stainless steel.

And this will not only maintain their good-looking appearance but also make it easier for people to clean them.

Moreover, some electronic products, elevator interiors, door panels, cold storage panels, etc., people also use anti-fingerprint stainless steel.

In this way, the improvement of corrosion resistance also improves their durability.

In addition, some medical equipment requires high sanitation.

At this time, the anti-fingerprint stainless steel avoids more bacteria and some complicated sterilization work.

However, some products appear as finished products.

For some special products or long-distance transportation, they cannot withstand the pressure of assembly.

Therefore, people need to assemble at the place of use. Moreover, the process of assembly is as important as the process of manufacturing the product.

Overall, it’s application is wide.
