There are many coatings in the construction industry. Some coatings play a decorative role, while others play a protective role. Among them, there is a kind of paint called metallic fluorocarbon paint that has both a decorative effect and a protective effect on metal. Metallic fluorocarbon paint is mainly used on metal surfaces to protect metal building materials for a longer period of time. So what is the construction process of metallic fluorocarbon paint? What is metallic fluorocarbon paint? The editor below will give you a detailed introduction.
What is metallic fluorocarbon paint?
Metallic fluorocarbon paint is a high-efficiency, multi-purpose, chemically cured two-component room-temperature fluorocarbon polymer. Cured coatings, metallic fluorocarbon paints have excellent durability, protection, decoration and other excellent properties. Long-term outdoor use and artificial accelerated aging tests have shown that the fluorocarbon bonds connected to the fluorocarbon resin molecules in the metallic fluorocarbon paint can resist the degradation of ultraviolet rays, showing extremely excellent durability, ultraviolet resistance and weather resistance, making the metal fluorocarbon paint Carbon paint coatings stay looking like new for a long time, reducing maintenance requirements.
Metallic fluorocarbon paint construction technology
1. Spraying. Drying time: at least 15 hours. ?Number of construction passes: one or two passes. It is best to apply it twice to ensure the performance of the topcoat.
2. Sanding: Use 600~800 mesh fine sandpaper to sand. When sanding, the force should not be too heavy to avoid wearing through the primer film, but it must be done carefully and thoroughly. Otherwise, after the topcoat is sprayed, a smooth coating film will not be obtained, and the gloss will even appear uneven (flowering).
3. Dust removal: Dust must be removed with a rag (blowing with a spray gun will not meet the requirements). If the dust is not removed thoroughly, a smooth coating film will not be obtained after the topcoat is applied, and particles will appear.
4. Construction requirements: After spraying, the color should be uniform and the gloss should be consistent. After sanding and dust removal, the surface of the coating film is smooth and free of dust and various dirt. There is a coating film about 50~80μm thick on the surface of the putty layer, and there is no leakage.
5. Construction ratio: Mix the main paint and curing agent strictly according to the ratio required by the manufacturer's instructions, then add an appropriate amount of diluent (adjust the viscosity according to the climate and temperature to apply - 4 cups for 18 to 23 seconds). Filter with a 100-mesh filter and must be used within 4 hours, otherwise the mixture will gel and deteriorate, affecting its sealing effect and adhesion.
6. Filtration: After preparation, the mixture must be filtered through a 100-mesh filter. The mixture must be continuously stirred during placement to avoid precipitation.
7. Spray gun model: W-71, etc.
8. Construction method: Metallic fluorocarbon paint must be sprayed, and solid-color paint is best applied by roller.
9. Number of construction passes: two.
10. Construction requirements: The glitter powder is evenly distributed and the density is equivalent to the sample. No sagging. There is no uneven light and shade or blooming. The gloss is uniform, the feel is delicate, and there are very few particles on the coating film. (Note: It is best to cover the surface with metallic paint. Solid color paint can be covered or not.)
Perhaps from the editor’s above text, you don’t know exactly what metallic fluorocarbon paint is? In fact, There are still many applications of metallic fluorocarbon paint in our lives. In terms of small items, the towel rail in our bathroom looks like a matte surface and is not easy to rust. This is mainly because there is metallic fluorocarbon paint on the surface. . There is also the Bird's Nest, the Olympic building in my country. The reason why it is made of metal but is always shiny and does not oxidize is also because of the metallic fluorocarbon paint on the surface.
