彩涂板對涂層的選擇要考慮的要素很多，它主要包括涂層種類、涂層厚度、涂層顏色和涂層光澤度。另外，有時(shí)侯還要考慮涂層的底漆和背面涂層的要求。目前用于彩色涂層鋼板的涂料種類有聚酯涂層（PE）、氟碳涂層（PVDF）、硅改性涂層（SMP）、高耐侯涂層（HDP）、丙稀酸涂層、聚氨脂涂層（PU）、塑料溶膠涂層（PVC）等。 PE涂料對于材質(zhì)有良好的附著性，彩涂鋼板易于加工成型，價(jià)廉且產(chǎn)品多，顏色和光澤的選擇余地大。聚酯涂料對

耐紫外光性與涂膜耐粉化性，并不理想，因此PE涂料的使用仍需受到一些限制，一般用在空氣污染不嚴(yán)重的地區(qū)或需多次成型加工的產(chǎn)品。

and luster choice is large.Polester coating is not ideal for UV resistance and coating powder resistance, so the use of PE coating still needs to be subject to some restrictions, generally used in the air pollution is not serious areas or need multiple molding processing products.
