Seal stainless steel: various possibilities

Oil is still used today to seal steel and stainless steel surfaces. However, the application is not without problems. In recent years, it is above all nanotechnology, which is becoming increasingly important in sealing. So also when sealing stainless steel.

Different methods of sealing stainless steel

Steel and stainless steel can be sealed differently. Various processes have proven useful for this: lack Stainless steel painting

  • Stainless steel oxidizing or passivating
  • Stainless steel oil
  • Sealants based on nanotechnology
  • Painting as a seal

The coating of stainless steel and steel is probably the best-known sealing technique used. The properties of the different paints speak for themselves. Flexible lacquers for stainless steel parts, which are exposed to large temperature differences (thermal expansion), mechanically very resistant to abrasion, good protection against acids and alkalis, depending on the lacquer.

Seal with oils

But painting also has a considerable disadvantage - paints are generally not transparent and painting is not always desirable. In professional catering kitchens, which are almost traditionally made of hygienic stainless steel, surface oiling has long been a good sealing option.

Surface Protection by Oxide Coatings

Oxidizing, such as blackening or anodising stainless steel, which is actually a black oxidation, is also widely used, but is also limited in concentrated solutions (such as strong acids). Moreover, these methods are not desirable everywhere.

Modern nanotechnology for sealing

This is where we come to nanotechnology. These are the smallest parts that can be practically programmed in the properties. The parts are so extremely small and combine in one application, creating a completely smooth surface. Because dirt or dust particles always remain in the recesses of materials, even if they are microscopic.

Nano Sealers Provide Comprehensive Protection

However, nano sealants have an absolutely smooth surface, so particles hardly support them. Therefore, dirt can be removed very quickly by simply wiping away. This applies to limescale as well as oily, acidic or lye-containing soiling and much more. In addition, a nano-seal becomes really hard, which also provides excellent protection against mechanical impact.

The seal will last for a very long time

With scratches, depending on their properties, such seals can even "heal" themselves again by simply closing the scratch. However, real nanoproducts are not quite cheap. However, you have to see that in relation to time. The protection can last up to twelve months depending on the quality and intensity of use. So you have to convert the relatively high price of nanoproducts to such a long time span.

Look for real nano-sealers

You also need to make sure that they are genuine nanoproducts. The term is not protected, so even "free riders" advertise with nanotechnology, although it is not. Therefore, you should be interested in nano-sealings only for products of established brand manufacturers.

Tips & TricksSealing the stainless steel surface is basically very similar for all nano-sealants. On the product container, however, there is a corresponding instruction manual for high-quality nano-seals.
