Powder Coating has the advantages of environmental protection and superior performance in the past few decades, in metal products and heat-sensitive material products, with the rapid popularization and application.
And fast coil coating due to the requirement of surface coating, coating thickness, etc. So the application of powder coating on the coil coating has been limited. In recent years, increasing environmental awareness among the public and stricter government environmental regulations have accelerated the demand for environmentally friendly coating technologies, making the development of sustainable coating solutions increasingly important.
MEIAO first used technological innovation to improve the quality of products, and actively committed to environmental protection, popularizing and applying powder coatings in coil coating, powder coating
For a coil coating manufacturing company, set coating equipment and coating technical support, and new product development as one of the coil of powder coating, the solution for end users to provide environmentally friendly products.
Powder Coatings:
To end carboxyl fast curing weather resistance type polyester resin as the main body, cooperate with fast curing agent, after reasonable formula design, preparation equipment preparation in a specific powder.
Powder product has the characteristics of particle size small, scattered not reunion, spraying coating achieve 28—38 microns, surface flow leveling effect is good, can achieve 5 to 20 years of fixed number of year of the outdoor weather resistance, and according to customer requirements, can be achieved from the clean, anti—bacterial, anti—corrosion coating surface with a specific function, excellent comprehensive performance.Product specific gravity 1.1—1.5 g/m³, in 32 microns of film thickness, can achieve 18 to 26 m²/kg of the spraying area.
MEIAO first used technological innovation, committed to the popularization and application of thin film type powder coatings, successively in coil, thin coating of powder coating applied to several invention patents,
and the company has independent intellectual property rights.

Coating Equipment:
The coil powder coating system is divided into two main sections: the powder application zone and the powder melting and curing zone. The powder application zone is equipped with advanced electrostatic spray guns designed for high-speed coating, ensuring uniform powder distribution across the coil surface. The powder melting and curing zone utilizes halogen and medium short-wave infrared heating technology to rapidly melt and cure the applied powder coating. This advanced process offers fast curing, improved production efficiency, reduced energy consumption, and environmentally friendly operation while producing a durable, high-quality finish.
MEIAO was first designed and developed for coil coating powder coating equipment to realize the high—speed coating of 60—100 m/min, production process, and no volatile, no odor, no wastewater emissions, to achieve the
whole process of coating completely meets the technical requirements of environmental protection.
MEIAO is first actively committed to environmental protection, the popularization and application of powder coatings in coil coating, continuous technological innovation, improving the quality of the coating production line, and has applied for several coil patents in the field of powder coating equipment for patent for invention and utility model patents.
Coating Technology:
MEIAO has an efficient and professional technical team, in the positive development of coil (thin coating type) of powder coating solutions for new technology, and at the same time, can provide timely insight into the latest needs of customers, providing quality technical services. Mai fu coating solution, according to the customer‘s actual demand, is equipped with a full set of technical documents, operation procedures, testing standards,and other standard documents, active communication with the customer, training, equipment upgrades, optimization, and powder coating to provide free technical guidance and technical support.
