Three pre-treatment checks to prevent peeling of stainless steel paint.
Stainless steel's passive film hinders adhesion. Here are three checkpoints for pre-treatment to prevent peeling.
The stainless steel coating peels off immediately. If changing the paint doesn't stop it, the cause is in the pre-treatment. ────────────── ■ Cause of Occurrence The surface of stainless steel has a passive film known as an oxide layer, which has properties that make it difficult for general chemical treatments to be effective. This leads to poor adhesion and is the main cause of peeling. ■ The Truth If you paint without removing the film, an anchor effect does not occur between the coating and the material, and adhesion cannot be secured. Residual oil due to insufficient degreasing also worsens peeling. ■ Improvement Measures Create surface roughness through blasting treatment to enhance the anchor effect. Using a primer specifically for stainless steel is also effective. Please utilize materials that can confirm the pre-treatment conditions.
