With accurate mirror steel roller and the all through PLC controlling system, DODO is capable to finish pre-coating at in one operation Three-Coat Two-Dry paint systems. DODO can provide the pre-coated aluminium coils with thickness 0.03~1.50mm and width 600~1600mm.
In Chemical Conversion line the substrates are degreased and cleaned off the lubricating oil, anti-oxidation oil and stains, as well as the setting out of impurities like silicon, magnesium, iron, copper etc. from the surface. Applying of Henkel technology and chemicals, a honeycomb oxidation film is formed on the surface of aluminium substrates which enhances the adhesion between the paint and the coil.
In Precision Coating line the chosen paint is coated on the surface of coil according to the customers' requirements. In the dustless coating cabinet, with advanced three roller reverse coater, the thickness of and appearance of coat are well controlled. There are three temperature zone in the curing oven, which perfects the coat performance of anti-solvent, hardness, flexibility and remains the good gloss, adhesion and anti-corrosion ability.
FEVE (4F type)
A new coating based on all tetrafluoroethylene resins with excellent weatherability and excellent chemical and chemical resistance, excellent gloss retention, anti-chalking and discoloration, superior overall performance over PVDF, providing gloss up to 80%, colorful The requirement is minimal in color range.
Polyester coating
Polyester coatings are universal coatings with a wide range of properties, providing good flexibility, adhesion and moldability, up to 80% gloss, wide range of color options and low cost, and resistance to chemical attack in outdoor applications , Is a mid-level durability of a product.
Wear-resistant coating
This kind of coating is made of polyurethane or polyester mixed with polyamide, which has good durability and is better than polyester coating in weatherability. The added polyamide adds a texture to the overall paint effect and the surface roughness can also be fine-tuned. The greatest benefit of this coating is its high abrasion resistance, which is a good indoor and outdoor coating for normal use. Ordinary gloss at 30% + / 5, up to 40%.
Acrylic coating
Modified system coating is the product before the popularity of polyester coating, the current use is limited. In general, the performance of less polyester coating, but has good fluidity.
EPOXY epoxy resin
It has good anticorrosion performance and good adhesion. It is usually used as primer.
