The quality of the pretreatment (cleaning and chemical coating) determines the quality of the coating, directly affecting the flexibility and impact resistance of the coating.It determines the coating adhesion of color coated products.

The purpose of primary coating, fine coating and curing is to coat the coating on the substrate surface, and to volatilize the organic solvent of the coating through heating, so that the organic coating and the substrate closely combined.

Coating and curing directly affect the appearance quality and physical and chemical properties of color coating board, which is the key link of production control.

General PVDF coated aluminium sheet The hardness tested with a pencil is only Hb, which can only be used for general decorative purposes.

For the project with complicated processing technology or easy contact with hard objects, it is easy to scratch or scratch the surface.Anti-scratch PVDF coated aluminium sheet Adopt the particle anti-scratch coating curing process, the strength is more than 5 times of the ordinary PVDF coated aluminium sheet , can resist the scratch of sharp objects.

PVDF coated aluminium sheet Nitric Acid Resistance Test Standard

Pour 100mL of analytically pure nitric acid with a mass fraction of 60%~68% into a 200mL~250mL large mouth bottle, cover the sample on the bottle mouth, keep the coating facing down for 30 minutes, rinse and wipe dry , Observe the color change immediately after placing it for 1 hour, compare the color of the acid-exposed and unexposed surface layer, and measure with a colorimeter.
