Coating formula: transparent powder coating formula

Core tip: transparent powder coating is usually used in special high-grade decoration field 1、 Transparent powder formulations of various systems 1 Acrylic acid system ingredient M / g acrylic resin 80 curing agent (dodecanedioic acid) 20 leveling agent 0.8 other auxiliaries 1 total 101.8 2 Formulation of polyester system: M / g polyester resin 93tgic7 leveling agent 0.8, other auxiliaries 1, 101.8 in total 3 Mixed system formula ingredient M / g polyester resin (mixed polyester) 50 epoxy resin 50 leveling agent 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 Home of coatings: transparent powder coatings are usually used in special high-grade decoration fields 1 Transparent powder formulas of various systems 1 Acrylic system formula component M / g acrylic resin 80 curing agent (dodecanedioic acid) 20 leveling agent 0.8 other additives 1 total 101.8 2 Polyester system formula component M / g polyester resin 93 TGIC 7 leveling agent 0.8 other additives 1 101.8 3 in total, M / g polyester resin (mixed polyester) 50 epoxy resin 50 leveling agent 0.8 other auxiliaries 1 101.8 4 in total, M / g epoxy resin 96 curing agent 4 leveling agent 0.8 other auxiliaries 1 101.8 in total The value should not only have good transparency, but also have excellent yellowing resistance Choose the liquid leveling agent without adsorption or the leveling agent for transparent coating Choose high purity curing agent In order to improve the durability, a small amount of anti ultraviolet additives can be added During grinding, 0.1% alumina can be added properly for sieving, and its storage stability can be improved properly 2、 General technical indicators of transparent powder technical indicators applicable standards coating appearance is smooth and flat, good fullness, transparency, transparency, clear, no yellowing, no fogging, visual gloss (60 °)% ≥ 105 GB / T 9754-88 impact strength / (kg · cm) ≥ 50 GB / T 1732-93 flexibility / mm ≤ 2 GB / T 1731-93 surface hardness ≥ 2H GB / T 6739-96 cupping test / mm ≥ 6 GB / T 9753-88 adhesion / grade 0 GB / T 9286-98 QUV test /% ≥ 90 (313nm, 1000h light retention rate) GB / T 14552-93 salt spray resistance test / mm 2 (test 1000h corrosion width and 240h Cass test) GB / T 1771-91 without mechanical impurities, loose without agglomerations (visual test); powder coating density: (1.15 ± 0.05) g / ml III process As the anti pollution ability of transparent powder is poor, the process control in the whole production process should be strict, otherwise shrinkage, dyeing and other defects are easy to occur The quality of raw materials is the basic condition to ensure the quality of transparent powder coating products Therefore, the technical indicators of raw materials, such as resin gelation time, softening point, and reactive functional group, must be spot checked regularly to ensure that the product quality meets the needs of customers If the formula has stability and continuity, it is necessary to control the product quality of the same batch or different batches of the same powder coating 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,
