Color coated products(Color steel sheets)are the highest value added among cold rolled products, which are manufactured by a process of bake hardening after being coated with various colors on the surface according to demand from customers and final users on the substrates of CR, GI, EG, AL, and SUS. It is called a nominal of PCM to the painted product, which was formed as a cut plate or coil before being fabricated into a steel sheet.
-Color coated steel sheets that were painted and dried with polyester.
-It is a generally used produst whose workability, weather resistance, and durability are excellent
-The range of colors and brightness are so wide that it is used for various purposes including constructional interior and exterior materials, assembling metals, and partitions.
-Substrates : GI, EG, CR, AL
-Characteristics
: Thickness(The upper + the bottom)-5+15㎛
: Brightness(60˚ GLOSS METER)-20~80%
: Workability (based on a thickness of material)-2T, 180˚ BENDING, TAPING, NO PEEL OFF(No flaking phenomenon)
: Hardness (MITUBISH UNIPENCIL, 1Kg)-B~H
: Hardness (MEK RUBBING, 1Kg)-more than 50times

-Steel sheets applied with a paint of Silicon resin and dried
-weather resistance is more excellent than that of polyster steel sheets that are used in construction materials principally
-Substrate:GI

:Hardness (MITUBISH UNIPENCIL, 1Kg)-B~H
:Hardness (MEK RUBBING, 1Kg)-more than 50 times

-Product applied and hardened with a paint of fluorine resin which has a symmetric structure and contains fluorine (F) an inert gas,
-A very high weather resistance and chemical resistance have been realized taking advantage of an excellent molecular exterior materials of buildings ong a seashore where weater conditions ard severe and that require a long time of duration
-Substrate: GI
-Usage : sandwich panels, roof fabrication steel sheets, building in a factory
-Characteristics
:Thickness (the bottom +the upper)-5+20㎛
:Brightness(60˚ GLOSS METER)-20~50%
:Workability(based on a thickness of material)-0T, 180˚ BENDING, TAPING, NO PEEL OFF(No flaking phenomenon)
:Hardness (MITUBISH UNIPENCIL, 1kg)-B~HB

-Used ing home appliances and metal devices that require special coating functions such as high workabilitym, high brightness, high clearness, and printing feature,
-Substrate:CR, GI/GA, EG
-Usage:refrigerator, washing machine, air conditioner, electronic range, and home appliancess
-Characteristics
:Thickness(the bottom + the upper)-8+17㎛, 50+20㎛
:Workability(based on a thickness of material)-0T, 180˚BENDING, TAPING, NO PEEL OFF(No flaking phenomenon)
:Hardness (MITUBISH UNIPENCIL, 1kg)-B~H
:Hardness (MEK RUBBING, 1Kg)-more than 50times

-Suitable to seachore and chemical plant where the corrosion os severe taking advantage of an excellent anti-corrosion
-Excellent workability : Excellent workability in bending, cutting, and fabrication that make possible to fabricate with various forms,
-Excellent surface feature : Possible to be applied in high class materials of van and complex panel
-Possible to express with carious kinds of colors, brightness, and weathrer resistance by applying with various paints
-Durability of coating is excellent that it need not any extra expenses in repair and painting
-Substrate: aluminum(Thickness:0.45~2.0mm, Width : 700~1680mm)
-Usage : Interior and exterior materials of building
Coating materials are defined as fluid chemicals able to carry out the required function by forming a dried film layer when applied to an object surface, as follows
these consist of organic and inorganic pigments designed to provide various colord including a phsical pigment for film efficiency reinforcement etc.
these disperse and stabilize the pigment, and then adhere the pigment rto the coating surface. Resins are the most important ingredient in determining the substantial characteristics of film
these refer to any additional material designed to improve the coating material and the film efficiency. comsisting of a hardening agent, a surface active agent, a plasticizer and a dispersant.etc
Factors that affect on duration of a color coated product(PCM steel sheets)
Ultraviolet in the sunlight rays makes to cause discoloration and fracture of a coatin
Whitening, reduction of brightness, and doscoloration will be enhanced ing an area with much moistyre
Sulfurous acid gas and nitrogen oxide gas in the air cause a discoloration and crack of a coating by combining with water and then transferring into sulfuric acid or nitric acid and even up to a damage of metal qualities
