4. Category of Finish Coats
Among all the ingredients of coils coatings, resin and pigment have the function of duction, 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 colors, resistence of ultra-violet radition, strong outdoors durability, chalking resistance, strong adhesion to the base metal, plenty of colors and relatively lower cost compared to the same quality.
(4) Polyvinlidence fluoride
The finish coat of this kind features in its excellent retention of color, resistence of ultra-violet radition, outdoors durability, chalking resistance, resistance to solvent, formability, good dirt resistance, finite colors and high cost.
