Between the car topcoat and the
car primer, between the
car repair paint and the old paint layer, there will be poor adhesion phenomenon. What is the reason?
1. the surface clean is not clean or not prepared properly. If the abrasive dust on the primer layer, or other surface contaminants are not completely removed, the topcoat layer will not be in good contact with the primer layer, resulting in a barrier to poor adhesion.
2.car topcoat and the car primer is not matched, or primer and the substrate is not matched, or the primer layer is not dry on the spray paint.
3.Polish is not enough.
4.Thinner has poor quality, poor solubility.
5.metal background paint is stored for a long time, in the spray varnish, varnish and the base paint, the adhesion becomes poor.
