This is the phenomenon of paint thickening. Due to the quality of spray paint, the resin in the car paint will also crack due to ‘shrinking’. In recent years, the world demand for non-stick coatings has increased at a rate of 20% to 25% per year.This kind of coating is widely used in household appliances, cooking utensils, automobiles, machinery, chemical industries and other industries because of its low surface energy, low friction coefficient and easy sliding properties. According to the medium and state of the coating, non-stick coatings can be divided into water-based, solvent-based and powder-based types.
Repeatedly flow and shake before use, or pour out all the paint and stir well. This is a very fine crack, which will continue to penetrate the car paint until it ‘breaks through’ the entire color paint layer.Teflon 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 period is longer, which leads to precipitation. The thickening of the color paint is mainly due to the reaction between the pigment and the paint base. The initial stage of cracking is difficult to detect with the naked eye.
Teflon spraying is a special coating whose coating surface is not easily adhered to or easily removed after being adhered to by other viscous substances. 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-forming mechanism and main influencing factors. When the naked eye can detect it is already serious. Do not store for too long. Pay attention to spraying with Teflon to prevent the car paint from cracking. Some anti-precipitation agents can also be added, such as aluminum stearate, hydrogenated castor oil, modified bentonite, etc. Teflon spray or varnish loses the consistency of the factory, thickens, thickens, or even cannot be used during storage.
When waxing and polishing, you will find streaks on the car body because of the presence of car wax in the cracks. This ‘skin disease’ can only be cured by repainting. PTFE coated fiberglass tape Manufacturers Teflon 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. The research and development of Teflon spraying in my country is still in its infancy, and there are few products, far from being able to meet domestic demand. For example, zinc white, aluminum white and other salt-based pigments react with the organic acid in the paint base to produce metal soap. The prevention method is: often move the paint during storage and reverse the bucket method, such as horizontal or upside-down
