Stainless steel fingerprint-free plate refers to coating a protective layer of transparent colorless to yellowish liquid on the surface of the stainless steel plate. After baking at high temperatures, this transparent nanomaterial is firmly combined with the stainless steel surface with various textures to form a transparent, hard, and solid protective layer.
Fingerprint free is generally divided into bright fingerprint-free and matte fingerprint-free according to the degree of reflection. The bright light without a fingerprint has a strong reflection, which can make the stainless steel plate more bright and beautiful in appearance, and is also the most common one; If there is no fingerprint in the matte, the reflection will be weaker. Without careful observation, you can’t tell whether there has been a fingerprint. The matte fingerprint is low-key and more durable, but the price is much more expensive than the bright light.
Stainless steel plates without fingerprints have the following advantages:
1. Improve the rust resistance of stainless steel. A fingerprint-free film can effectively prevent external corrosion, avoid oxidation reactions of stainless steel, and prolong service life.
2. It is easy to clean the board surface stains. If the stainless steel surface is directly cleaned with metal cleaner, it is easy to blacken the plate surface; The boards that have been made without fingerprints are easy to clean, do not need metal cleaning agents, and are not easy to stick fingerprints, dust, feel fine, and have good fingerprint resistance and antifouling effects.
3. The board surface is not easily scratched. No fingerprint can form a dense film on the surface of stainless steel and has high hardness, which can resist general scratch damage from the outside.
4. Strong appearance and texture. The fingerprint-free stainless steel plate has the characteristics of moistening and brightness while retaining a good metal texture.
5. Improved touch. The fingerprint-free film changes the cold and stiff characteristics of stainless steel itself, making it soft and delicate, warm and elegant.
For stainless steel color plates, fingerprint-free processing should be done. If the color-plated stainless steel plate is exposed to the air for a long time, it will change color over time, resulting in uneven color and no primary color effect. After fingerprint-free treatment, the stainless steel plate can avoid direct contact with the outside world, and the color will remain bright and new for a long time. In addition, once the color stainless steel plate is scratched, it will directly reveal the true color of stainless steel, which has a large contrast and affects the appearance. However, the plate without fingerprints can avoid the impact of color loss caused by small scratches.
There are indeed many advantages to making fingerprints free. For example, copper-plated plates can only be delivered without fingerprints, but not all of them must be made. The cost of making fingerprints free will increase, and rose gold without fingerprints will make the color yellow. Therefore, whether to do or not to do so depends on the customer’s affordability, market habits, and needs.
