    Core tip: the correct choice and use of paint is an application of technical issues, but also an important topic, master well, can get a better effect

    The selection of coating should be in accordance with certain matching principles to meet the requirements of service conditions for coating performance

    Coating substrate matching: for surfaces of different materials, appropriate coating varieties must be selected to match them

    For example, baking film-forming coating that needs high-temperature drying cannot be selected for wood products, paper, leather and plastic surfaces, and coating that needs only low-temperature drying or self drying must be used

    The primer used for various metal surfaces shall be based on different metals Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form

    It is a new type of coating, because of its own advantages and more and more known by people

    Let's introduce Akzo Nobel Powder coating

    Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products

    After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment

    Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: the correct choice and use of paint is an application of technical issues, but also an important topic, master well, can get a better effect

    The selection of coating should be in accordance with certain matching principles to meet the requirements of service conditions for coating performance

    Coating substrate matching: for surfaces of different materials, appropriate coating varieties must be selected to match them

    For example, baking film-forming coating that needs high-temperature drying cannot be selected for wood products, paper, leather and plastic surfaces, and coating that needs only low-temperature drying or self drying must be used

    The primer used for various metal surfaces shall be selected according to different metals

    For the surface of plastic film and leather, vinyl and polyurethane coatings with good flexibility should be selected

    Adhesion between coatings: the primer with strong adhesion shall be selected for the finish with poor adhesion

    In the case that the performance of primer and finish is good but the combination between the two layers is not good, the intermediate transition layer can be used to improve the adhesion performance of the bottom layer and the surface layer

    Coating coating compatibility: the primer shall be matched with the top coat, preferably the drying primer and the drying top coat, and the self drying primer shall be matched with the self drying top coat, which shall be matched with the primer and the top coat of the paint base

    Effect of service conditions on compatibility: the compatibility of primer and finish under service environment shall be considered

    Matching between coating and auxiliary materials: Although the auxiliary materials of coating are not the main film-forming materials, they have a great influence on the film-forming process and coating performance during the curing of coating construction

    The function of auxiliary materials is mainly to improve the construction performance and application performance of the coating, and to prevent the coating from defects, but they must be used properly, otherwise they will have adverse effects

    Matching of coating and construction process: whether the matching of coating and construction process is appropriate or not directly affects the coating quality, coating efficiency and coating cost

    The coating construction process shall be carried out in strict accordance with the construction process specified in the coating specification
