PVDF fluorocarbon paint

Secondly, the construction process of metal fluorocarbon paint:

① Basic treatment

dust removal: dust removal with a rag, the more seriously polluted parts of the use of high-pressure water gun for washing and cleaning. If the dust is not thorough, the paint will not be able to get a smooth coating after construction, there will be particles.

grinding: use 600~800 mesh fine sandpaper sanding. When sanding, the force should not be too heavy, so as not to wear the primer coating, but it must be carefully and thoroughly. Otherwise, after the topcoat is sprayed, a smooth coating film will not be obtained, and even uneven light and shade (flower) will appear.

② Putty layer construction

batch scraping elastic crack-resistant leveling putty: mix putty according to the product specification, batch scraping once to level the base layer, and local unleveled surfaces can be leveled twice.

putty layer surface has a layer thickness of about 50 ~ 80μm thick coating, no leakage phenomenon.

③ Special sealing primer construction

Spray the special sealing primer for metallic paint: spray the special sealing primer for elastic metallic paint after the putty layer has passed the acceptance. The paint film shall be uniform and continuous during spraying.

④ Construction of anti-rust middle layer paint

Spray elastic fluorocarbon intermediate layer paint. The paint film is required to be uniform during spraying. Each separating surface can be sprayed separately, or multiple separating surfaces can be sprayed continuously.

⑤ Metal fluorocarbon paint construction

intermediate paint. The paint film is required to be uniform during spraying. Each separating surface can be sprayed separately, or multiple separating surfaces can be sprayed continuously.

(Note: Different color metallic paint construction, at the junction of the need to focus on strengthening protection, and a color of the construction in another color after drying.)

⑥ Spraying finish coat

The matching topcoat shall be sprayed on the completely dried metal surface, with uniform thickness and no omission.

drying time: at least 15 hours.
