Coating classification: amine cured epoxy coating

Core tip: brief introduction: amine cured epoxy coating is an epoxy resin coating with amine as curing agent, mainly including polyamide cured epoxy coating, amine addition cured epoxy coating and polyamide cured epoxy coating, which belongs to solvent type epoxy coating Features: amine cured epoxy coating features as follows: ① Amine cured epoxy coating belongs to two-component coating, which is cured at room temperature, prepared before coating, with short service life and inconvenient construction; ② Amine cured epoxy coating has high hardness and brittleness; ③ Amine cured epoxy coating has good corrosion resistance, especially aliphatic solvent, enoic acid, dilute alkali and salt; 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 Brief introduction: amine cured epoxy coating is an epoxy resin coating with amine as curing agent, mainly including polyamine cured epoxy coating, amine addition cured epoxy coating and polyamide cured epoxy coating, belonging to solvent type epoxy coating Features: amine cured epoxy coating features as follows: ① amine cured epoxy coating belongs to two-component coating, solidified at room temperature, prepared before coating, with short service life and inconvenient construction; ② amine cured epoxy coating has high hardness and brittleness; ③ amine cured epoxy coating has good corrosion resistance, especially aliphatic hydrocarbon solvent, enoic acid, dilute alkali and salt; ④ Amine cured epoxy coating has poor leveling property, and the coating film is prone to orange peel, edge shrinkage and other defects; comparison of amine cured epoxy coating: Project: typical variety of polyamide cured epoxy coating: h53-33 red epoxy antirust primer h04-5 white epoxy enamel h52-30 gray epoxy anticorrosive coating h52-33g various colors of epoxy anticorrosive coating H52-32 aluminum powder epoxy anticorrosive coating h52-80 strontium yellow epoxy anticorrosive coating h52-18 aluminum powder epoxy anticorrosive primer commonly used curing agent hexanediamine, diethylenetriamine more hexanediamine, diethylenetriamine adduct 200 × 3, 300 × 3, 650 × 3, 651 × 3, 50 × 3, new 1 × 3, 250 × 3 coating performance good solvent resistance, slightly poor chemical resistance excellent, slightly poor curing speed slow Service life / D 11 12 whitening is not easy to be cured easily It is necessary to be cured when it is not necessary It is necessary to be cured It is good to use two-component coating When it is used, the two components are mixed at 1:1, not more than 20% of the theory at most In addition, the solvent is carefully selected The two components are strictly proportioned, otherwise the performance of the coating film will decline The two components need to be matured at 1-2 when they are evenly mixed h After curing, the construction coating is not easy to whiten; the use period is short, and the coating needs to be used up in time after mixing; the multi amine is volatile, toxic, and pay attention to construction safety; the coating is generally dried for 1 day at 25 ℃, but it needs 7 days after thorough drying The formulation and application of the coating are similar to that of the polyamine; the construction is simple, and the coating can be directly constructed if the two components are not matured after mixing; the coating has a longer service life; the coating can be constructed in a humid environment under the condition of proper curing agent The two components must be cured after mixing; the leveling property is good after curing; the epoxy equivalent / amine equivalent = (1.25-1.42): 1 is suitable for normal temperature curing, and the coating can have better water resistance; if it is used for underwater engineering corrosion protection, the coating needs asphalt modification; it takes 7-10 days for the paint film to dry completely at normal temperature, but only 4-5 hours at 60 ℃ It can be used for anticorrosion of chemical equipment, pipeline and storage tank It is suitable for anticorrosion of large-scale iron and steel equipment and petrochemical pipeline It is suitable for anticorrosion of metal and non-metal coating, especially for anticorrosion of light metals such as aluminum and magnesium It can be used as enamel It can be used for coating of underground pipeline, underwater facilities, plastic film, rubber, leather and paper It is very important for the solvent selection of polyamine cured epoxy coatings Epoxy resin component can be used as solvent with mixture of alcohol and aromatics or mixture of ketone, alcohol and aromatics; curing agent component can be used as solvent with mixture of alcohol and aromatics This kind of coating is easy to produce problems after construction Therefore, high boiling point solvents, such as diacetone alcohol and cyclohexanone, are often added to the coating products during construction However, the use of ester solvents should be avoided because esters react with amine curing agents to reduce the curing effect 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,
