Classification of color-coated panels and their performance comparison
Color-coated steel plates are mainly classified according to their topcoat coatings, including PE polyester color plates, PVDF fluorocarbon color plates, HDP high-weather-resistant polyester color plates (also called high-performance polyester color plates), and SMP silicon-modified color plates. This article introduces the performance characteristics, service life, application fields and comparison of different coated color plates.
1PE polyester color board
Introduction: Polyester color coating is a metal paint color plate made by using PE polyester coating on the metal plate and then baking at high temperature
Key Features: Good adhesion, wide range in formability and outdoor durability, moderate chemical resistance.
Specifications: thickness 0.17-1.5mm, width 1250mm or less.
Substrate: galvanized/aluminized zinc.
Coating structure: two layers on the front/one layer on the back.
Coating thickness: 15-25um/5-10um
Roll weight: less than or equal to 10 tons.
Roll inner diameter: 510mm/610mm.
Roll outer diameter: 800-1500mm.
Service life: 5-10 years
Application field: light steel structure industrial workshops, warehouses, movable houses, civil residences, flat-to-slope roofs, etc.
2SMP silicon modified color board
Introduction: Silicon modified color coating is a metal baking paint color plate made by using SMP silicon modified resin coating on the metal plate and then baking at high temperature
Main features: Good hardness, wear resistance and heat resistance of the coating film, as well as good external durability and non-chalking, but limited gloss retention and flexibility.
Specifications: thickness 0.17-1.5mm, width 1250mm or less.
Substrate: galvanized/aluminized zinc.
Coating structure: two layers on the front/one layer on the back.
Coating thickness: 20-25um/5-10um
Roll weight: less than or equal to 10 tons.
Roll inner diameter: 510mm/610mm.
Roll outer diameter: 800-1500mm.
Service life: 10-15 years
Application field: light steel structure industrial workshops, warehouses, movable houses, civil residences, flat-to-slope roofs, etc.
3HDP high performance color board
Introduction: High-performance color coating is also called high-weathering color plate. It is a metal-painted color plate coated on a metal plate with HDP high-performance polyester paint and then baked at high temperature.
Main features: Due to the different resin molecular structures of high-performance polyester and ordinary polyester, high-performance polyester has better resistance to ultraviolet damage and better durability. Its main properties are between polyester and fluorocarbon
Specifications: thickness 0.17-1.5mm, width 1250mm or less.
Substrate: galvanized/aluminized zinc.
Coating structure: two layers on the front/one layer on the back.
Coating thickness: 20-25um/5-10um
Roll weight: less than or equal to 10 tons.
Roll inner diameter: 510mm/610mm.
Roll outer diameter: 800-1500mm.
Service life: 10-15 years
Application field: It is suitable for light steel structure buildings with high anti-ultraviolet performance requirements, flat-to-slope roofs, etc.
4PVDF fluorocarbon color plate
Introduction: Fluorocarbon color plate is a metal paint color plate made by using PVDF polyvinylidene fluoride paint on the metal plate and then baking at high temperature.
Main features: It has extraordinary stability, and can maintain the stability of various properties in acid-alkali and polluted environments; excellent durability, fluorocarbon color boards can still maintain good color and luster outdoors for 20 years; excellent Processing performance, the painted color board has high flexibility, impact resistance, and can also be post-embossed.
Specifications: thickness 0.17-1.5mm, width 1250mm or less.
Substrate: galvanized/aluminized zinc.
Coating structure: two layers on the front/one layer on the back.
Coating thickness: 20-25um/5-10um
Roll weight: less than or equal to 10 tons.
Roll inner diameter: 510mm/610mm.
Roll outer diameter: 800-1500mm.
Service life: more than 20 years
Application field: Suitable for chemical plants, power plants, steel mills, high-speed rail stations, etc. with high requirements for UV resistance and weather resistance.
