Small wrinkle powder coating

   In the formula of powder coatings, wrinkle agent is an auxiliary agent that changes the surface tension of the melting film makes the film shrink produce wrinkles orange lines when the powder coating is melted leveled solidified. The function of wrinkle agent is that when the powder coating is baked cured, the surface tension of melt leveling film is large, while that of wrinkle agent is small. Because of the poor compatibility between two materials with different surface tension, the surface tension of the small surface tension can completely reduce the surface tension of the large surface tension prevention. The coexistence of two different surface tension materials makes the coating film Produce uneven wrinkles. The solvent based coating is about 60-65% of the coating composition, while the small wrinkle powder coating is almost 100%. The powder attached to the sprayed object can be recycled. Generally speaking, the use of powder coating technology can improve production efficiency economic efficiency.
