PE(Polyester ) Coating: high molecular polymer as monomer and addition of alkyd, is a UV-resistant coating. It can be classified matt and glossy according to coating gloss. The compact molecule structure makes paint surface lustre and smooth, Which assure good printing on the panel surface, With a Warranty of 8-10 years for weather resistance, It is specially applied for internal decoration and signboard.
Brushed Panel, Which is made some special Processing on natural aluminium. presents the nature and beautiful brushed appearance together with modern and elegant.
Wooden and Stone Panel can be processed by film-sticking and Roller Coating. The former means stick one layer of films with granite or wooden Pattern by Technology. and the later roller coating is painted and roasted for three or four times with better weather resistance.
Mirror Finish Panel, Which needs anodic oxidation finishing on the aluminium surface, the finishing makes the surface like a mirror, Mainly used for indoor.
No matter whether a soft white or a vibrant red is selected, Solid colours are always a good choice when a uniform appearance without special effects is required. The gloss of Solid colours is between 30% -40% according to Gardner Scale, High Gloss Colors upon 95% also available. If you mention the colour for placing an order, please specify the gloss rate as well.
The different appearance of colour and gloss under various light conditions and viewing angles gives these surfaces a vivid impression and brings them alive. According to the Gardner Scale, the gloss of metallic colours is between 30%~50% and the gloss of special effect colours is between 70%-80% by one more clear coating.
