Nowadays, many aluminium sheets with colour coated are painted with various colors, which are very beautiful, so they are widely used on decorations. And most of the spray paints used are oil-based paints. Then everyone knows what is the classification of the paint used for color coated aluminum sheet ? Next, we will give you a detailed introduction.
1. Polyester(PE).
The hardness of the paint film of aluminium sheets with colour coated is worse than that of acrylic, but it has good flexibility and processability (good T-bend, good processing performance); currently the coil steel and aluminum coil systems are more commonly used.
2. Polyurethane.
The paint film has good toughness, good adhesion, wear resistance, but is easy to yellow and chalk; it is generally used in the leather industry and furniture industry, and the rolled aluminum coil system is generally used as a primer (our fluorocarbon primer);
3. Acrylic.
The paint film of aluminum coil has high hardness, but poor flexibility (T bending difference); suitable for non-machined parts and high-hardness index coatings, such as automotive paint, thin aluminum sheet and foil (within 0.04) is currently in use;
4. Epoxy.
The paint film has good adhesion, corrosion resistance and abrasion resistance, but high brittleness (T-bend difference); it is generally used in floor paint and anti-corrosion industries, and the color-coated aluminum coil system is generally used for back paint (polyurethane foam, viscose, etc.) );
5. Fluorocarbon(PVDF).
The paint film of PVDF coated aluminium sheet has excellent corrosion resistance, super long weather resistance, strong adhesion, but the paint film is soft; it is widely used in the field of super weather resistance, and the aluminum coil system generally uses 2 fluorine (PVDF) and 3 fluorine (FEVE).
A good paint will play an important role in the aluminium sheets with colour coated, so everyone should look for it when choosing a paint.
