Peeling of paint coatings and its causes

2026-02-15View Original

Thread Content

The phenomenon in which one or more coatings separate from the coating beneath them, or all of the coatings completely detach from the substrate. Reactions between different coatings: Poor coating compatibility leads to insufficient adhesion between the coating and the substrate. First, the quality of the paint is poor; low-quality paint tends to peel off, and it may even result in insufficient hardness of the paint ; Secondly, an unfavorable substrate environment, such as cracks on the substrate surface or excessive moisture content, can easily lead to insufficient adhesion between the coating and the substrate.
