Powder Coating and Fluorocarbon/ Polyvinylidene Fluoride (PVDF)
Our fully-automated vertical powder coating line comes equipped with advanced spray booth and guns from Wagner, Germany. Together with our horizontal powder coating lines, they can deliver a total annual capacity of 24,000 metric tonnes.
The ALBECoat fully integrated powder-coating process offers additional surface finishing that meets the ever-growing demands of our customers and which adheres to the RAL International Colour Code Standard. This single application coating provides a wide-range of solid and metallic colours with different gloss levels and options for texture finish.
In addition, the ALBECoat Fluorocarbon/ Polyvinylidene Fluoride (PVDF) finishing is another high-quality process which involves thinly applying wet-paint to workpieces via electrostatic spray to form a film, which is further heated to polymerize and cure the coating. Fluorocarbon/ Polyvinylidene Fluoride (PVDF) uses a 4-coat system provides excellent colour consistency against fading and UV rays.
