Common knowledge of coating: comparison between cement based waterproof coating and polyurethane waterproof coating

Core tips: 1 Compared with environmental protection and construction performance, waterproof coating is water-based waterproof material, polyurethane is oil-based waterproof material Water based coatings have obvious advantages First of all, the oil-based coating generally contains toxic and peculiar smell volatile substances At the same time, the viscosity is large and the workability is poor, so it is difficult to construct Secondly, the solubility of oil and water is poor Therefore, the requirements for the dry humidity of the construction base surface are similar to that of coil products The water-based materials are superior to the oil-based materials in the above aspects 2 Compared with the anti-aging properties of the material, polyurethane is afraid of ultraviolet light, so it can only be used for waterproof of concealed works, while cement based waterproof coating is large 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 Coating home news: 1 Compared with environmental protection and construction performance, waterproof coating is water-based waterproof material, polyurethane is oil-based waterproof material Water based coatings have obvious advantages First of all, the oil-based coating generally contains toxic and peculiar smell volatile substances At the same time, the viscosity is large and the workability is poor, so it is difficult to construct Secondly, the solubility of oil and water is poor Therefore, the requirements for the dry humidity of the construction base surface are similar to that of coil products The water-based materials are superior to the oil-based materials in the above aspects 2 Compared with the anti-aging properties of the material, polyurethane is afraid of ultraviolet light, so it can only be used for waterproof of concealed works, while the cement based waterproof coating is mostly made of inorganic sealant and acrylic emulsion, so the anti-aging property is excellent 3 Compared with the price, polyurethane waterproof material requires a thickness of 1.5-2.0mm, a material consumption of at least 2.5-3.0kg per square meter, a large amount of material and a high labor cost, while cement-based waterproof material according to the national standard requires 1.0-1.2mm, a small amount and a low cost 4 From the comparison of construction safety, the oil polyurethane construction in the closed environment will not only cause poisoning to the construction personnel, but also cause explosion However, as a water-based cement-based waterproof coating, it has no such disadvantages, so it can be safely used 5 Compared with the quality stability, the polyurethane coating is generally synthesized by reaction in the manufacturer Its equipment performance, process control, raw materials and many other aspects may cause quality differences, especially in some small manufacturers, whose conditions are simple and the quality of employees is low, so it is difficult to guarantee the quality The cement-based coating is a non reactive product, which can only be processed according to the formula in the factory, so the quality stability is absolutely superior to polyurethane coating 6 Compared with the external quality of the coating, the surface tensile strength of polyurethane coating is very low, impact resistance, puncture and other properties are very poor, while the cement-based coating is generally divided into two types, rigid and flexible economic type, with excellent impact resistance It is much better than polyurethane coatings in the protection of finished products 7 Compared with other materials, polyurethane coating can not directly paint and stick ceramic tiles, while cement-based coating can directly carry out the above construction on its surface 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,
