Defoamer A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam. Commonly used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols. The additive is used to prevent formation of foam or is added to break a foam already formed. The defoaming agent is resistant to high temperatures, light in color, has good water dispersibility, is not prone to fish eyes and shrinkage cavities, and has no oil slicks or demulsification. It is suitable for all types of coatings and emulsions, water-based resins, and adhesive systems.

Differences between Spray Paint and Electrostatic Powder Coating: 1. The effect of Spray Painting is mirror. The effect of Powder Coating is mostly frosted surface with small holes. 2. The paint is thinner than the powder. The paint is about 30 microns in size. The powder particles are about 60 microns. 3.The smell of paint is harmful to health. Small powder pollution, small and environmental impact on workers' health. 4. Paint is volatile matter, so the Curing temperature in the Curing Heating System is below 150 degrees Celsius. The temperature of the Powder Spraying workpiece in Curing Oven needs to be between 180 and 220 degrees Celsius. 5. The same grade of Powder is cheaper than lacquer. 6. The strength of the powder is better than the ordinary paint. 7. Powder Spraying can be in place once. And the powder that falls into the groove in the Spray Room can still be used repeatedly to save cost. Hebei Hanna technology CO., LTD. 's Fast Automatic Powder Color Changing System can change color rapidly for 15 minutes. It saves manpower and time. This is really good for you if you have more color on your workpiece to change. And the Big Cyclone can achieve 99.2% recovery. It's economical and environmentally friendly.
