Meklon High Viscosity M-505 Soil Primer
Product Description
M-505 Soil primer is the basic material for the surface of the body steel plate, and it is the first layer of the body paint combination coating. Its main function is to provide adhesion for the coating and prevent corrosion of the body steel plate. M-505 Soil primer Generally, it does not have the ability to fill the surface defects of the car body, but it can make the bare metal surface suitable for the attachment of putty, primer and topcoat. Therefore, the M-505 primer is used as a medium layer between the painted surface and the coating. make the two firmly combined.
It is very important to choose the Soil primer correctly, which is not only related to the anti-corrosion and adhesion of the Soil primer, but also to reduce the cost of spraying and facilitate construction, as well as prolong the durability of the paint film and meet the quality requirements of automotive coating. In addition, the construction process also has a great relationship with the quality of the coating, such as the thickness, uniformity, dryness of the paint film, the correct use of thinners, the construction environment (temperature, relative humidity) and the pretreatment of the coating surface. Factors can affect the quality of primer coating.
Characteristics and Construction Key Points of Soil Primer
There are many types of primers used in car body paint repair. When choosing a primer, it needs to be selected according to the different requirements for the quality of the paint surface, the surface material of the substrate, and the matching topcoat. Commonly used body repair paint primers include phosphating primers, epoxy primers, and polyurethane primers. The following is a brief introduction to the characteristics and construction points of commonly used primers.
Properties of Soil Primer
The soil primer has excellent adhesion to the metal surface of the car body after surface pretreatment;
The soil primer layer has excellent corrosion resistance and chemical resistance;
The soil primer layer should have the performance of passivating the metal surface and excellent sealing to the outside world, that is, the anti-"three seepage" performance (water seepage, oxygen seepage, ion seepage);
In addition to good compatibility with metal, the soil primer also has the characteristics of good compatibility with putty, intermediate coat primer or topcoat layer; the primer should have good construction performance
