Material selection of coating | necessary knowledge for use: thermosetting powder coating standard

It is suggested that the powder coating is a new type of coating without solvent, and thermosetting powder coating is also one of them However, any kind of coating can not be flawless, so what is the standard of using thermosetting powder coating? What is thermosetting powder coating? Thermosetting powder coating is generally composed of resin, curing agent, pigment, filler and assistant It uses thermosetting resin as film-forming material, adding crosslinking curing agent to form a hard coating after heating It has a good decorative property, and because of the low molecular weight prepolymer after curing, it can form a network intersection 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: powder coating is a new type of solvent-free coating with the characteristics of pollution-free and recyclable, and thermosetting powder coating is also one of them However, any kind of coating can not be flawless, so what is the standard of using thermosetting powder coating? What is thermosetting powder coating? Thermosetting powder coating is generally composed of resin, curing agent, pigment, filler and assistant It uses thermosetting resin as film-forming material, adding crosslinking curing agent to form a hard coating after heating It has a good decorative, and because the low molecular weight prepolymer can form a network of crosslinked macromolecules after curing, its corrosion resistance and mechanical properties are also very good It is generally divided into four categories: thermosetting polyester powder coating, thermosetting epoxy powder coating, thermosetting polyurethane powder coating and thermosetting ring polyurethane powder coating Standard for thermosetting powder coating 1 Under normal environment, the thermosetting powder coating is characterized by uniform color, no foreign matters and loose powder It moves in 120 mesh test sieve without residue 2 Observe the coating color of thermosetting powder coating under scattered sunlight, it should be within the range of color difference, and the coating film is allowed to have slight orange peel 3 If the coating does not appear blistering, cracking, peeling, powder falling or obvious discoloration, the alkali resistance of the coating can reach the qualified standard 4 If the film does not appear blistering, cracking, peeling, powdering or obvious discoloration when tested with hydrochloric acid, its acid resistance will reach the qualified standard 5 When the film made of thermosetting powder coating is placed in boiling water for a period of time, if the film does not appear blistering, cracking, peeling, powder dropping or obvious discoloration, its boiling water resistance will reach the qualified standard 6 Mark the base material of the coating thoroughly, and check the corrosion or coating damage spreading from the marking If there is no blistering, cracking, peeling, powder falling or obvious discoloration in the area from 2mm to 5mm of the marking, then its salt spray resistance meets the qualification standard The above is the standard of thermosetting powder coating Although it is a new type of environmental protection coating, due to the characteristics of the powder, protective measures should be taken during use to avoid harm to the body caused by inhalation of the powder 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,
