Application of Pigment Carbon Black in Plastic Primers

    Everything that uses paint for painting usually needs to be coated with a layer of primer first, because if the paint is directly sprayed on the surface of the object, it is easy to fall off. Even if the pigment carbon black is added to the paint, this problem will not be avoided. So it is necessary to first apply a layer of primer containing pigment carbon black on the surface of the object, which can not only fill the depressions on the surface of the object, but also enhance its adhesion, making the re sprayed paint less likely to bubble and fall off.
    What is primer, what is the special pigment for primer, carbon black, and what are the purchasing standards for plastic primers?
Primer refers to a coating that is directly applied to the surface of an object as a solid foundation for the topcoat.
Plastic primer refers to the primer applied in the plastic industry.
Carbon black, a pigment used for plastic primers, is a colorant mainly used for processing black plastic primers. Whether black plastic primer is good or not, and whether the blackness is enough depends on the choice of the pigment carbon black used for plastic primer.
    The primer processed with pigment carbon black for plastic primer mainly requires firm adhesion on the surface to increase the adhesion of the upper layer of paint and improve the decorative properties of the topcoat. According to coating requirements, it can be divided into first coat primer, second coat primer, etc. When choosing the pigment carbon black for plastic primers, it is important to choose the appropriate one, learn more, ask more relevant questions, and conduct more experiments to ensure that the purchased pigment carbon black for plastic primers can be applied to your own production process.
    Standard for purchasing pigment carbon black for plastic primer:
    a) The primer processed with pigment carbon black for plastic primer must have good adhesion to the plastic substrate.
    b) The primer processed with pigment carbon black for plastic primer should not excessively corrode the plastic surface. The diluent in the plastic primer has a certain degree of swelling on the plastic substrate, and the swelling layer enhances the adhesion between the primer and the substrate.
    c) The plastic primer processed with pigment carbon black should also have strong dispersion performance, so that hair lines do not appear after spraying on the surface of the object.
    d) The primer processed with pigment carbon black for plastic primer should have fast drying properties, so that the paint applied on it can dry quickly.
