What paint should the stainless steel be sprayed with? Polyurethane paint.
A two-component paint with a curing agent, it can be cured thoroughly with its curing agent at room temperature without baking.
The paint film is strong and tough, with full luster, strong adhesion, water resistance, wear resistance and corrosion resistance. It is widely used in high-grade wood furniture and can also be used on metal surfaces.

Extended information:
The paint film of this kind of stainless steel paint is bright, plump, hard and wear-resistant, resistant to oil, acid, chemicals and industrial waste gas, good electrical properties, and can be miscible with a variety of resins. The formula can be adjusted in a wide range to meet different requirements. need.
Widely used in wood, automobile, aircraft, machinery, electrical appliances, instrumentation, plastics, leather, paper, fabrics, petrochemicals and other specialties.
Some varieties of coatings have good protection function but poor decoration; some varieties (such as nitro paint, etc.) have good decoration but poor protection function. However, polyurethane paint is both protective and decorative, and can be used for the coating of high-grade wood, pianos, large passenger aircraft, etc.

Stainless steel paint cannot be used without professional equipment. The following conditions need to be met before painting, because the stainless steel surface is bright and easy to spend.
1. To pull the surface of stainless steel, use a wire brush or sandpaper to pull the surface.
2. For cleaning, there are special chemicals for cleaning, and pickling can also be used. If the quantity is not large, it can be cleaned by conventional cleaning methods.
3. When using stainless steel paint, it is recommended to use spray paint, because when spraying paint, if the adjustment is not thick enough, there will be flow phenomenon, if the adjustment is too thick, the paint will fall off and the spraying will be uneven, spraying can avoid this problem .
4. Baking paint, that is to say, good construction goes into the paint baking room. For baking paint for a certain period of time, the temperature should not be too high, the time should not be too long, and it should not be too low or too early.

Precautions:
The corrosion resistance of stainless steel decreases with increasing carbon content. Therefore, most stainless steels have a low carbon content, up to 1.2%, and some steels have a carbon content even lower than 0.03% (such as 00Cr12).
The main alloying element in stainless steel is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, the Cr (chromium) content of general stainless steel is at least 10.5%. Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu.
Stainless steels are generally classified into martensitic steels, ferritic steels, austenitic steels, austenitic-ferritic (duplex) stainless steels and precipitation hardening stainless steels.
In addition, according to the ingredients can be divided into:
Chromium-nickel stainless steel, chromium-nickel stainless steel and chromium-manganese-nitrogen stainless steel, stainless steel plates and strips for pressure equipment for pressure vessels.
