Because the surface of stainless steel products is very smooth, and many of them have been chemically treated on the surface of stainless steel products, they can achieve the effect of rust prevention. There are many stainless steel products in daily life that do not need painting, such as stainless steel tables, stainless steel pipes, stainless steel shelves and so on.

However, there are also many places that need to be sprayed with topcoat to achieve the beautiful effect of the product. Stainless steel is a kind of base material with corrosion resistance, high temperature resistance and good processability. Widely used in industry, home decoration industry, food and medical industry. And its surface is very smooth. It is difficult for ordinary paint to completely adhere to the stainless steel surface, so pretreatment is very important when making this kind of paint.

Precautions for stainless steel painting:

The construction conditions are that the temperature is higher than 5℃ and the humidity is lower than 85%. Dip coating, brush coating and spray coating can be used for construction. Before painting, the paint solution should be stirred evenly. If the viscosity of the original paint is high, a small amount of water can be added, and the amount of water added should not exceed 20%. When adding, the paint solution should be stirred to ensure uniformity.

When painting stainless steel, impurities on the surface, such as oil stain, dust and wood wool, must be removed. If necessary, putty can be scraped, and it can be polished and leveled after drying. After construction, the paint film can be dried by itself or at low temperature. When drying, the baking temperature is not lower than 40℃ and not less than 20 minutes. Construction twice, the first time should be completely dry.

It is forbidden to mix with other paints and organic solvents during construction to prevent deterioration. After the construction, all used appliances should be washed with clean water, and the remaining paint should be sealed and preserved.

Stainless steel paint is easy to corrode, so special attention should be paid to the maintenance of stainless steel. Stainless steel paint is also vulnerable to climate and acidity. Leakage of corrosive substances such as double itch water and acid battery will cause certain damage to stainless steel paint surface. Acid rain falling on the surface will also cause damage to stainless steel paint, and the color will penetrate from the existing on-site paint layer or primer layer to the new topcoat layer.
