Category and film thickness of primers
The category of the primer includes epoxy, polyester, acrylic Acid, polyurethane, etc.
In general, the primer is chosen in accordance with the usage, Environment condition, processing stage and finish coat. The Film thickness of the primer is usually 5~7 um.
(1) Epoxy primer
The epoxy primer has a strong adhesion to the base metal And good properties in waterproof, alkali-proof and chemical Resistance, which is the original primer for the coiled steel, Having a poorer flexibility than that of other primers.
(2) Polyester primer
The primer has strong adhesion to the base metal and Excellent flexibility, which is relatively sensitive to damp Environment and has a chemical resistance poorer than That of epoxy primer.
(3) Water-soluble acrylic acid primer
The primer of this kind has strong adhesion, excellent Flexibility, lower organic solvent and low-temperature curing.
(4) Polyurethane primer
The primer of this kind has excellent chemical resistance, Durability and flexibility.

Category of finish coats
Among all the ingredients of coil coatings, resin and pigment Have the function of duration, and the primers commonly used Consist of polyester, silicon modified polyester, polyvinylidene Fluoride, high durability polyurethane, etc.
(1) Polyester
The finish coat of this kind has strong adhesive force, a Variety of colors, wide scope of properties in formation and Durability outdoors, moderate chemical resistance and low Cost.
(2) Silicon modified polyesters
The membrane of the finish coat of this kind has excellent Rigidity, abrasion resistance, thermal resistance, good Outside durability, chalking resistance, high retention of Color and luster, ordinary flexibility, moderate cost, etc.
(3) High-durability polyester
The finish coat of this kind has excellent retention of color, Resistance of ultra-violet radiation, strong outdoors durability, Chalking resistance, strong adhesion to the base metal, Plenty of colors and relatively lower cost compared to the Same quality.
(4) Polyvinylidene fluoride
The finish coat of this kind features in its excellent retention Of color, resistance of ultra-violet radiation, outdoors Durability, chalking resistance, resistance to solvent, Formability, good dirt resistance, finite colors and high cost.
