China PPGI/PPGL Steel Coils - Prepainted Galvanized & Aluzinc Coils Supplier and Factory
Color Coated Steel Coil/Sheet(PPGI/PPGL)
Primers
Epoxy – Polyester (Chrome – Chrome Free); for excellent corrosion and inter-coat adhesion. The Back Coat of the PPGI/PPAZ strip is Generally Polyurethane(PU)-Compatible Epoxy coated in order to have adhesion in case the coils are used for insulated sandwich panel manufacturing.
Topcoats
R.M.P (Regular Modified Polyester)
Regular Modified Polyester is most widely-used coil coating with durable Polyester paint and heat dried. It is applied to interior/exterior materials with no heavy drawings. Thanks to its variable colours and glosses with an economic feasibility. RMP coated products are used for exterior panels and interior design purposes that do not require excessive processing. It generally displays superior workability, durability, and weather resistance and used for a variety of purposes; offered in a wide array of colours and degrees of polish.
Matt and wrinkle effect can be added to the top finish.
- Roofing & siding panels
- Interior Partition
- Building Interior/Exterior
- Sandwich panels
- Roof, Gutter
- Steel furniture
- Shutter, Door, Garage Door, Iron Frame, etc.
S.M.P (Silicon Modified Polyester)
Silicon Modified Polyester is a silicon resin modified Polyester paint coated and heat dried. Due to its higher durability than the Regular Polyester, generally applied for building construction. SMP assures economic benefits under circumstances of sea-side or industrial zones. 10-15 years limited warranty provided.
SMP products are coated and baked with paint containing silicon resin. It is suitable for coastal area due to its excellent weather resistance.
