General knowledge of coating: analysis of the requirements of latex paint for film forming AIDS

Core tip: the film forming AIDS in emulsion paint are actually high boiling point solvents that help to form polymer film in the latex paint area An effective film builder must be a good solvent for emulsion polymers In the latex paint, the film-forming assistant adsorbs on the polymer particles, softens the particle surface due to the dissolving action, so that the particles are easy to deform, close together under a small force, and because the film-forming assistant is low TN, it can provide more free volume under the construction temperature, so that the polymer molecular chains diffuse and fuse with each other to form a film That is to say, a polymer with high TN value is in use 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 Coatings home: the film builder in latex paint is actually a high boiling point solvent that helps the polymer film to be added to the latex paint area An effective film builder must be a good solvent for emulsion polymers In the latex paint, the film-forming assistant adsorbs on the polymer particles, softens the particle surface due to the dissolving action, so that the particles are easy to deform, close together under a small force, and because the film-forming assistant is low TN, it can provide more free volume under the construction temperature, so that the polymer molecular chains diffuse and fuse with each other to form a film That is to say, a polymer with a high TN value can form a film at a lower temperature when a film forming aid is used A polymer has its characteristic Tn value due to its composition and structure The polymer emulsion also has a MFT value corresponding to its Tn value If the film forming agent is added to the emulsion, the minimum film forming temperature can be reduced, but the Tn value of the polymer itself does not change, so that the higher film performance and the lower construction temperature are balanced Of course, people are demanding that there be as few side effects as possible Before film-forming, the film-forming assistant can not volatilize, so it is required to volatilize slower than water Once film-forming is completed, the film-forming assistant completes their mission Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
