Color coated
aluminium coil has been one of the most popular decorative material because of its stable performance and strong corrosion resistance. Its superior properties is owed to the color coating.At home and abroad, there are four types of paint for aluminum: PVDF,acrylic paint, epoxy paint and PE. What is the best paint for the color coated
aluminum coil? Let's know them one by one.PVDF CoatingPVPD paint is a coating with fluororesin as the main film-forming substance. Of these four paints, PVDF paint is of the best anti-aging performance and the strongest UV-resistant ability. In addition, it has excellent weather resistance, heat resistance, low temperature resistance, chemical resistance, unique non-stickiness and low friction. Its shortage is that the color choice is limited.PE CoatingPE, that is polyester, is another paint we are familiar with. Polyester paint is mainly made of polyester resin. It is of good adhesion, rich colors, excellent outdoor durability and medium chemical resistance. Its price is relatively lower than that of PVDF paint.There are two improved polyester, which are HDP and SMP. HDP is of excellent color retention, UV resistance and high cost-effectiveness. SMP is of good hardness, abrasion resistance and heat rsistance, but it has the average flexibility and medium cost.Acrylic PaintIt is a kind of self-drying weather-resistant anti-corrosive coating which adds polyethylene rubber and weather-resistant fillers and additives on the basis of traditional acrylic resin. It is convenient to paint and consolidate at room temperature.Epoxy PaintIts main components are epoxy resin and curing agent. Epoxy paint film has good adhesion, corrosion resistance and wear resistance, but it is of high brittleness. It is generally used for back paint of
aluminum coils.The choice of different paints for coated
aluminum coil also means that prices will vary. So you should choose a proper paint according to the
aluminum coils'use and occasion. That will be the best paint for the aluminium colour coated coils.
