Coating common sense: what is the water resistance of coating?

Core tip: [news] the national standard has made certain requirements for the water resistance of the coating The specific inspection method: prepare the paint film of standard thickness on the asbestos cement board of the specified size, and maintain it at constant temperature and humidity for 7 days Seal the edge with a mixture of 1:1 rosin and paraffin Immerse 2 / 3 in distilled water or tap water, and check the test plate for loss of light, discoloration, blistering, wrinkling, peeling and other phenomena after soaking for the time specified in the standard, as well as the recovery time after drying, so as to judge the water resistance of the coating The water resistance of the coating and the water resistance of the waterproof coating are two completely different indexes, which have good water resistance 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: [news] the national standard has made certain requirements on the water resistance of the paint The specific inspection method: prepare the paint film of standard thickness on the asbestos cement board of specified size, and maintain it at constant temperature and humidity for 7 days Seal the edge with a mixture of 1:1 rosin and paraffin Immerse 2 / 3 in distilled water or tap water, and check the test plate for loss of light, discoloration, blistering, wrinkling, peeling and other phenomena after soaking for the time specified in the standard, as well as the recovery time after drying, so as to judge the water resistance of the coating The water resistance of the coating and the water resistance of the waterproof coating are two completely different indexes The coating with good water resistance does not necessarily have the waterproof function 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,
