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.
