The decorative effect of the coating and the role of protection is good or bad, not only with the metal substrate and the nature of the paint itself, but also with the choice of metal pretreatment process has a direct relationship. Coating pretreatment process and quality determines the adhesion of the coating and the substrate, adhesion and coating protection performance is closely related.
There are many kinds of surface pretreatment of stainless steel metal substrate, mainly combined with the structural characteristics of the coated object, size, yield and so on to choose. The main purpose of pretreatment is to remove the foreign matter on the surface of the substrate and at the same time to obtain a suitable surface roughness, in order to facilitate better adhesion of the coating. Traditional surface pretreatment methods include grinding, pickling, passivation and sandblasting, etc. With the development of technology, metal adhesion promoters are now commonly used to solve the problem.
Gui Sheng treatment agent stainless steel metal adhesion promoter sprayed between the substrate and paint coating, play a role in the bottom, so that the hinge on the substrate and paint coating to achieve effective adhesion, enhance the interlayer adhesion to achieve the purpose of solving the problem of paint fall, salt spray and other tests. Not only the use of stainless steel material surface spraying, but also in zinc alloy, aluminum alloy and other materials surface spraying process is also widely used to assist in strengthening the adhesion between the metal substrate surface and paint coating, metal hardware material spray rubber paint, UV paint, ordinary color paint, baking paint, such as paint problems in the use of the use of the effect is obvious.
