Brief instruction of epoxy resin coating
Marine anti-fouling, anti-corrosion engineering widely used epoxy coating - NPT epoxy anti-corrosion glue
Epoxy resin anti-corrosion coating is a widely used anti-corrosion coating, which has an important position in marine anti-corrosion coatings. For a long time, epoxy resin anti-corrosion coatings have the characteristics of corrosion resistance, chemical resistance, acid and alkali resistance, high strength, high hardness and wear resistance.
Epoxy resin anti-corrosion coating refers to a class of polymers containing two or more epoxy groups in the molecule, which can be combined with the curing agent to form a coating with high hardness, high adhesion, high chemical stability and high corrosion resistance. At present, there are many types of epoxy resin anti-corrosion coatings, and there are many kinds of bisphenol A epoxy resin coatings and phenolic epoxy resin coatings from the matrix resin classification alone.
At present, there are many varieties of epoxy resin anti-corrosion coatings, and we recommend more stable performance: NPT epoxy resin anti-corrosion coatings.
NPT epoxy resin anti-corrosion coating. It has the characteristics of high hardness and high adhesion after curing, and is not easy to be damaged, and its excellent acid resistance, alkali resistance and chemical resistance are also extremely important in anti-corrosion coatings. The development of epoxy resin anti-corrosion coatings will continue to be one of the focuses of the field of anti-corrosion coatings for some time to come.

NPT epoxy resin anti-corrosion coating is widely used in marine pipelines, valve anti-corrosion, chemical sewage, acid-base blending pool, waste acid storage tank, waste storage tank acid and alkali corrosion resistance, industrial valves and other fields. Cowinns supplied one type high pressure gate valves which coated with epoxy resin for potable water project.
