Main varieties of fusion bonded epoxy coating - 134

The fusion bonded epoxy powder coating is a one component, heat cured, thermosetting epoxy coating for metal corrosion protection The powder like epoxy resin is applied on the surface of the preheated steel products The powder is melted and solidified to form a uniform coating This process makes the coating have good adhesion and coverage on the pipeline transportation, valves, pumps and other objects The coating can prevent the corrosion of waste water, corrosive soil, hydrocarbons, chemicals and sea water, and the performance of the powder makes it easy to use manual or automatic methods of static electricity or air 1 The main characteristics are that no primer is required, which is particularly suitable for electrostatic or air spraying on preheat metal objects; electrostatic coating can be used on unheated metal objects, and then heating and curing; long gelatinization time can minimize the cold flow, sagging stratification or visible overspray that may occur when coating large and complex objects; It is especially suitable for forming smooth anti-corrosion coating in the pipeline or other objects; meeting the requirements of machining; easy to carry out surface inspection; being able to apply resin paint and acrylic paint as the color code; no sagging, cold flow and softening during storage, with long-term storage life in various climate environments; Light weight, saving transportation cost; can play a protective role in a large temperature range; can resist the stress of soil, with excellent adhesion and toughness; can prevent cathode stripping * excellent chemical resistance performance; long service life in water, sewage and other harsh environments; Coatings recognized by the environmental protection agency of the United States for use in contact with potable water also meet the requirements of c213 and C550 2 Operation steps: remove oil, grease and loose accumulation on the surface; - dust the surface to near white level according to the requirements of sspc-sp10 or NACE No.2; - cover with mechanical cover or scotch glass cloth tape 361, Scotch aluminum platinum tape 425; - preheat the object to the required temperature for solidification; - apply 134 powder to the surface of the object to the required thickness; - cure according to the curing requirements; - conduct visual and electrical inspection after the coating is cooled to detect the leakage point; - repair the leakage point 3 Curing instructions: 134 powder is applied to the object preheated to 149-232 ℃, and it shall be cured according to the curing guidelines to obtain the best performance If 134 powder is applied to the object not preheated by static electricity, the curing time shall be calculated from the object reaching the curing temperature After curing, the coating can be cooled with air or water to a temperature easy for inspection and operation.
