Common knowledge of coating: why does the coating for exterior wall insulation system have water repellency and air permeability?

Core tip: water is the enemy of the external wall insulation system, in the form of ice, water and steam In the maintenance structure, water migration is the result of a variety of migration phenomena It is mainly caused by the diffusion of water vapor, the driving of wet migration and the pressure difference It is manifested in leakage, freezing, condensation and blocked diffusion of water vapor When the external insulation system of the external wall seeps or leaks water, the water will make the insulation performance decline or even lose completely 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: water is the enemy of external wall insulation system, in the form of ice, water and steam In the maintenance structure, water migration is the result of a variety of migration phenomena It is mainly caused by the diffusion of water vapor, the driving of wet migration and the pressure difference It is manifested in leakage, freezing, condensation and blocked diffusion of water vapor When the external insulation system of the external wall seeps or leaks water, the water will make the insulation performance decline or even lose completely 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,
