PPGI & PPGL Sheet Coating

The total thickness of the pre-painted galvalume steel coil is composed of the
base steel – coating -primer – top paint – protective layer thickness.
The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm.
The thinner the base steel thickness, the higher the price of the ppgi steel coil,
because the processing cost becomes higher.

PPGI Production Process Flow Chart

Unrolling → Stitching machine → Entrance loop → Pretreatment → Initial coating → Bake → Cool down → Fine coating → Bake → Embossed film → Export loop → Inspection station → Cut → Coiling
In the above process, if the cleaning degreasing process is not handled well, the adhesion of the primer of the color coated plate to the galvanized sheet is not good, and it is easy to cause the top coat of the color coated steel coil to fall off during the press forming process.

Coating primer	Top paint coating
1) Epoxy primer, good adhesion, water resistance, alkali resistance, chemical corrosion resistance, poor single toughness. 2) Polyester primer, good adhesion, good flexibility, sensitive to humid environment, chemical resistance is not as good as epoxy primer. 3) Acrylic primer, good adhesion, good toughness and high pretreatment requirements. 4) polyurethane primer, chemical resistance, abrasion resistance, durability, toughness	1) Polyester resin, good adhesion, molding and outdoor durability.
	2) Silicon Modified Polyester (SMP)
	3) High weather resistant polyester (HDP)
	4) Polyvinyl fluoride (PVC)
	5) Polyvinylidene fluoride/fluorocarbon (PVDF) It has good formability and color retention, good outdoor durability and powder resistance, solvent resistance, limited color and high price.
