Common knowledge of coatings: four views on the merits and demerits of Waterborne Coatings

Core tip: first, after storage for a period of time, there will be layering of aqueous coatings One quarter of the upper layer is water quality solution, and the lower layer is coating particles Observe whether the water quality solution is colorless or yellowish, clear and clean, with less floating objects The poor coating water solution is turbid and there are more floats Second, a small amount of paint particles can be put into the clear water, gently stir, and observe whether the clear water is still clear, whether the size of paint particles is uniform, whether they are relatively independent in the clear water, and whether there is no adhesion phenomenon The inferior coating will be turbid immediately after agitation and the particle size will be differentiated Third, the coating film should not lose powder, 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: a look at aqueous coatings in storage for a period of time, there will be layering phenomenon, the upper quarter is water quality solution, the lower layer is coating particles Observe whether the water quality solution is colorless or yellowish, clear and clean, with less floating objects The poor coating water solution is turbid and there are more floats Second, a small amount of paint particles can be put into the clear water, gently stir, and observe whether the clear water is still clear, whether the size of paint particles is uniform, whether they are relatively independent in the clear water, and whether there is no adhesion phenomenon The inferior coating will be turbid immediately after agitation and the particle size will be differentiated Third, the coating should not lose powder, and has a certain washability, there is dirt can be washed with water After the high-quality products are wiped by the wet cloth, the color of the coating is bright as new, while after the low-quality products are washed several times, the coating will fade or even be damaged Four to see that the test report products must comply with the requirements of the national standards for synthetic resin emulsion coatings and the standards for the limits of harmful substances in interior coatings for interior decoration and finishing materials, the testing bodies must be approved by the State Technical Supervision Bureau and have the CMA detection mark 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,
