iform film thickness, and generally contain volatile organic compounds (VOCs). Liquid Paints are driven off during the curing or baking process. Solids form a film on the extrusion when the VOCs are gone the volume.
Powder Coating: is a multi-stage process to create a durable film or coating on the aluminium surface. It offers a virtually unlimited choice of colours and is also very durable.The aluminium is pre-treated to clean. An electro-statically charged powder is sprayed in the spray booths and attracted to the face of the aluminium to form an even coating. Then, it moves to a curing oven in order to melt or cure the charged powder to get an even paint coating with 60 microns thickness. As the powder coatings leave behind a film that can meet stringent performance criteria and do not contain VOCs, it is ideal for meeting environmental regulations on VOCs.
PVDF: finishes are mostly carried out on steel and steel panels. It has a wide colour range, fade resistance, and excellent durability. But, PVDF does Pperform as well like anodised finishes in abrasion resistance, formability, and small batch orders. Their maintenance and repair are also fairly easy to carry out.
