Teflo spraying often occurs precipitation phenomena during transportation and storage, such as sinking of pigments and fillers, but still ineffective after shaking. The reason is that the pigment or extender pigment particles are not finely ground, poorly dispersed, more fillers, reaction between the pigment and the paint base or corresponding adsorption, or the storage interval is long, leading to precipitation. The prevention method is: often move the paint during storage, and reverse the bucket method, such as horizontal placement and reverse placement. Do not store for too long. Repeatedly flow and shake before use, or pour out all the paint and stir well. Some anti-precipitation agents can also be added, such as aluminum stearate, hydrogenated castor oil, modified bentonite, etc.

Teflo spraying is a special coating whose coating surface is not easily adhered to or easily removed after being adhered to by other viscous substances. This kind of coating is widely used in household appliances, cooking utensils, automobiles, machinery, chemical industry and other industries because of its anti-adhesion characteristics such as extremely low surface energy, low friction coefficient and easy sliding. According to the medium and state of the coating, non-stick coatings can be divided into water-based, solvent-based and powder-based types.

Teflo spray or varnish loses its consistency, thickens, thickens, or even cannot be used during storage. This is the phenomenon of paint thickening. The thickening of the color paint is mainly due to the reaction between the pigment and the paint base. For example, zinc white, aluminum white and other salt-based pigments react with the organic acid in the paint base to produce metal soap. Pay attention to spraying with Teflo to prevent the car paint from cracking. This is a very fine crack that will continuously penetrate the car paint until it "breaks through" the entire color paint layer. The initial stage of cracking is difficult to detect with the naked eye. When the naked eye can detect it is already serious. When waxing and polishing, you will find streaks on the car body because of the presence of car wax in the cracks. Due to the quality of spray paint, the resin in the car paint will also "shrink" and crack. This "skin disease" can only be cured by repainting.

Teflo spraying water-based non-stick coating contains less organic solvent, good safety, and low environmental pollution, so it is most popular with users and has the largest output. In recent years, the world demand for non-stick coatings has increased at a rate of 20% to 25% per year. The research and development of Teflo spraying in my country is still in its infancy, and there are few products, far from being able to meet domestic demand. Based on this, this article focuses on discussing the basic idea of ​​preparing water-based non-stick coatings with fluororesin and binder as the main raw materials, and appropriately analyzes the film formation mechanism and main influencing factors.
