PVDF coated aluminium sheet description
PVDF coated aluminium sheet is a new kind of material, the surface is coated with a layer of fluorocarbon paint or polyester paint, so that the aluminum plate has UV protection, acid and alkali resistance, high weather resistance and other excellent properties, used in the outdoor PVDF powder coated aluminium sheet life can be as long as 20 years.
PVDF powder coated aluminum sheet is different from pe (Polyester) painted aluminum sheet. It is PVDF paint material coating on aluminum, normal thickness ranges from 1.0mm to 5.0mm, aluminum sheet using high-quality high-strength aluminum alloy plate 3003, 3105, 5052, 5754 processing.
STEK can produce according to the specifications customized by the customer. The professional color coating production line ensures the stable quality of the color aluminum sheet & plate.
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.

Application of PVDF coated aluminium sheet
PVDF coated aluminium sheet is a commonly used material in construction. It can be used as a common material in industrial products such as hardware, air conditioners, decorations, and transformers, etc.
With solid aluminum panel applications broaden, STEK coat PVDF painted aluminum sheet &coils, according to customer demand, has developed powder coating aluminum veneer, stone marble finish, wood finish etc. Daily can produce 4,500 to 5,000 square meters and annual production capacity of 1.5 million square meters, product performance and stability, more and more is applied to the interior and exterior projects, filling and unique style building.
Case of STEK color aluminum
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.
