Dip powder company: the advantages of liquid dip coating

Dip powder is rich in material sources, cheap and non-toxic. A wide range of color configurations can be configured in a variety of colors, and can also be configured with hard smooth, soft smooth, fine-grained, coarse-grained, matte, and luminous dips. The dipping powder paint film has strong adhesion, low temperature resistance, impact resistance, wear resistance, moisture resistance, salt spray resistance, tensile resistance, acid and alkali resistance, aging resistance, high pressure resistance, chemical resistance, and excellent weather resistance. Cracks and other properties will occur.


Dipping powder has excellent electrical insulation properties, and can maintain its properties even when soaked in brine solution. The dipping solution does not contain toxic and heavy metal ions, is antibacterial and environmentally friendly, the raw materials can be recycled, and the coating thickness can be controlled. There is almost no waste generated during the production process, and the production conditions are mild, which is conducive to environmental protection. The film has good flexibility, excellent tensile strength and elongation at break.

The high-temperature baking of dipping powder will sometimes affect the hardness or deformation of the workpiece, so the workpiece cannot withstand high temperature (160~280°C), and the immersion process is not suitable. Since the color-changing paint must be impregnated with plastic in separate tanks, it is not suitable to use liquid-impregnated plastic processing technology for paint products that require frequent discoloration. The product cannot sink in the impregnation solution, and the impregnation treatment technique should not be used. For cast iron casting workpieces with pores in the matrix itself, bubbles and pores are prone to defects during impregnation, so they cannot be impregnated.

Plastic dipping powder is not suitable for the whole or partial immersion of large workpieces due to the complicated operation of large workpieces and the difficulty in guaranteeing the quality of plastic films. Due to the large coating thickness of liquid immersion plastics, it is not suitable for products with thin film coating requirements.

Pretreatment (sand blasting, degreasing, derusting, phosphating, bluing or dipping treatment)→hanging→preheating (150℃~260℃, 5~15min)→dipping→drying and plasticizing (160~280℃ , 1~3min) → cooling (air-cooled or water-cooled) → hanging → inspection → packaging → shipment. In view of the advantages of liquid immersion plastic coating, it is widely used and the trend is increasing year by year, applicable to various industries. The color of the dipping process can be yellow, red, white, blue, green, black. The impregnated product is based on steel, and the weather-resistant polymer resin is the outer layer (0.5-1.0mm thick), which has the characteristics of corrosion resistance, rust resistance, acid and alkali resistance, moisture resistance, insulation, aging resistance, good hand feeling, environmental protection, and long life. , is a substitute for traditional baking paint and galvanized coating, and has a wide range of uses.
