Coating general knowledge: waterproof coating should not be applied in the weather with temperature above 40 ℃

Core tip: the coating is suitable for use in the environment of 5 ℃ - 40 ℃ However, when the temperature in the natural environment is too high, the water or solvent volatilizes too fast during the construction of water-based or solvent-based waterproof coating, and the coating gradually thickens in the construction process, making it difficult to brush, affecting the construction quality In the film-forming process, the temperature is too high, causing the surface water or solvent volatilization too fast, while the bottom coating If the medium moisture or solvent is not fully volatilized, it will be difficult to form the film It is easy to be mistaken that the film is dry and can continue to be constructed If the moisture is buried under the coating, foaming will occur At the same time, the film is easy to shrink and crack Reactive coatings are two 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 paint is suitable for use in the environment of 5 ℃ - 40 ℃, but in the natural environment, when the temperature is too high, the water-based waterproof During the coating or solvent waterproof coating construction, the water or solvent volatilizes too fast, and the coating gradually thickens in the construction process, making it difficult to brush, which affects the construction quality; in the film-forming process, the high temperature causes the coating surface moisture or solvent volatilizes too fast, while the moisture or solvent in the bottom coating is not fully volatilized, so the film-forming is difficult, which is easy to be mistaken as the coating film After drying, the construction can be continued The water is buried under the coating, which causes blistering At the same time, the coating is prone to shrinkage and cracks Reactive coatings are cured by chemical reaction of two components If the temperature is high, the reaction speed will be fast, the curing time will be short, and the construction operation time will be shortened, which will increase the difficulty of construction operation and the possibility of construction quality problems In addition, when workers operate in high-temperature climate, they are prone to fatigue, dehydration, heatstroke and other phenomena, affecting the quality of the project Based on the characteristics of the materials and the construction practice of the waterproof coating, the waterproof coating should not be constructed in the weather with the temperature above 40 ℃ 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,
