When low-molecular-weight substances or additives (such as stearates, plasticizers, etc.) are present in the coating, they will form a weak interfacial layer between the coating and the object to be coated, which will affect the flow of the paint to the substrate. Moisture, reducing adhesion.In addition, when the surface of the substrate is adhered with impurities such as water, dust, acid, alkali, etc., it also causes the appearance of a weak interface layer between the paint film and the substrate, hinders the wetting action of the paint liquid on the substrate, and reduces the polarity point. , resulting in a decrease in the adhesion of the paint film.
