Two ways to paint stainless steel

1. Patterned painted stainless steel belt

With the expansion of the use of stainless steel, there are problems of fingerprint pollution and corrosion caused by food and medicine in the use of household appliances and interior decoration materials. The countermeasure was to paint the stainless steel surface, but the original coloring paint damaged the metallic luster pattern of the stainless steel surface. To this end, in recent years, clear-painted stainless steel with excellent pattern properties, which can prevent fingerprint contamination and corrosion, has been developed, mainly used for cold-shielding and electronic instrument panels. The original pre-coated clear-painted stainless steel strip is not ideal in terms of weather resistance and corrosion resistance. With the advancement of pre-painting treatment technology, this problem has been solved, and the clear-painted stainless steel has been commercialized.

2. Functional painted stainless steel belt

Stainless steel is prone to adhesion and sliding scratch defects during stamping, so for applications where patterning is important, processing with a surface protective film is often required. However, this protective film needs to be peeled off by hand after stamping; under strict processing conditions, film fragments are unlikely to cause indentations on both sides of the stamped part. In addition, it is also important how to dispose of the waste film so as not to increase the environmental load. To this end, stainless steel, which can be painted and lubricated instead of the protective film, has been developed, and it has been widely used in various fields such as home appliances, appliances, and automobile mufflers. The lubricating paint is a wax component mixed in the paint film, so it has good lubricity. Compared with the non-scale stamping oil coating material, it has excellent deep processing properties, and can also omit lubricating oil. This paint film is divided into two types: soluble type and non-paint stripping type, which are degreased and depainted with strong alkali after processing.
