Common knowledge of coating: raw material composition of anti condensation coating

Core tip: anti condensation coating is an important functional coating, so what is the composition of anti condensation coating compared with general coating? (1) Base material anti condensation coating base material should be selected according to the environmental conditions of the application The application of anti condensation coating requires its coating to have good hygroscopicity, and it must have good water resistance when it is in wet or wet dry wet condition for a long time Obviously, the water-based architectural coatings that can meet these requirements are 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: anti condensation coating is an important functional coating, so anti condensation coating and general coating, anti condensation coating composition? (1) Base material anti condensation coating base material should be selected according to the environmental conditions of the application The application of anti condensation coating requires its coating to have good hygroscopicity, and it must have good water resistance when it is in wet or wet dry wet condition for a long time Obviously, the organic materials for waterborne architectural coatings that can meet these requirements are acrylate emulsion, inorganic base material, silica sol and so on The water resistance of silica sol is the best, but when silica sol is only used as the base material, the coating has poor coating performance, poor decorative effect, brittle and easy to crack Therefore, when using silica sol, it is best to use a proper amount of acrylate emulsion This kind of organic-inorganic composite has been introduced in the previous chapters In addition, another kind of cheap inorganic base material has not only strong moisture absorption, but also excellent adhesion and water resistance When white portland cement is preferred, it is usually referred to as white cement for short White cement has a certain strength after hardening with water and reaching a certain age Its strength will not decrease but increase when it is in water or humid environment for a long time Once it is dried, the porous structure in it can absorb moisture (water) strongly Therefore, the moisture absorption properties of the anti condensation coating made of organic base materials (acrylate emulsion) and inorganic base material (white cement and silica sol) are different Generally speaking, the moisture absorption performance of inorganic coating is higher than that of organic coating For the purpose of anti condensation, it is better to be machine-free, and inorganic anti condensation coating has advantages in cost, environment, energy consumption and other aspects However, white cement will set and harden in a few hours after adding water, and lose operability Even if adding retarder, the setting time can only be extended to a limited range Therefore, the anti condensation coating with white cement can only be made into two-component coating at present On the other hand, like silica sol, the anti condensation coating with white cement as base material is not good in operation (coating) and decoration It must be combined with other base materials, and the most effective one is acrylate emulsion 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,
