1. Different primers have different adhesion, toughness and corrosion resistance. Epoxy has good adhesion to the substrate, high corrosion resistance, but not as tough as other primers. Polyester has good bonding ability with base, excellent toughness, but not as corrosion resistance as epoxy. Polyurethane is a comprehensive primer. The primer is usually selected by the supplier according to the production process, application, corrosive environment, and the matching relationship with the topcoat.

2. Different types of topcoats differ in hardness, flexibility, adhesion, durability, etc. Polyester is currently the largest use of paint, general durability, hardness and toughness, moderate price. Silicon-modified polyester has high durability, luster and color retention, but slightly reduced toughness, and high weather-resistant polyester has high cost performance. Polyvinylidene fluoride has excellent durability, good toughness, but low hardness, low color available, high price. The surface paint of the painted board is mainly influenced by its usage, corrosive environment, service life, durability, processing mode and deformation degree.
