Organic coated steels are produced in the coil coating process when (organic) coating material is applied on rolled metal strip in a continuous process that includes cleaning, if necessary, and chemical pre-treatment of the metal surface and one-side or two-side, single or multiple application of (liquid) paints subsequently cured in ovens and finally rolled into coils.
Quality control system has been implemented as an effective instrument of high quality production and products in accordance with international standard ISO 9001, issued by TÜV CERT. Basic material for production of organic coated steels is hot dip galvanized sheets or cold rolled sheets without surface treatment.
BASIC PROPERTIES
The properties of coil coated flat product shall comply with requirements specified in international or national standards. Required properties, tolerances and standards should be indicated at the time of enquiry and order.
The inspection of the color of the organic coating consists of conducting a visual comparison between sample of the manufactured product and a reference sample of prior agreement. For a more thorough inspection, the difference in color can be measured instrumentally, however it should be noted that the type of measuring instrument or measuring method/system is influencing results significantly. Color cards, RAL tones often do not define exact colors and therefore only serve as a guideline. Color perception varies from one color to the other and from one finish to the other (gloss variations, embossed, textured, wrinkled, metallic pigmented, pearlescent coatings and finishes etc.). These specific finishes may exhibit aspect and color variation from one production batch to another. It is also important to maintain directionality to ensure color consistency.

Gloss is optical property of a surface characterized by its ability to reflect light.
If gloss is not specified in the order, standardly applied is satin gloss.

Depending on the end-use of coil coated flat products the performance properties and product flexibility shall be agreed at the time of enquiry and order. Product flexibility shall be evaluated by a T-bend test carried out on the exposed face. Flexibility of the product depends on the substrate thickness, the metallic protection and the organic coating. During the flexibility testing there shall be no visible cracks when the paint film is examined with a 10x magnification.

APPLICATIONS
ENVIRONMENT
For applications where the prepainted products are submitted to the influence of exterior atmospheres, the end user has to consider the environments for successful usage and correct product application for its long-term service.
how we produce
Organic coated steels are produced in the coil coating process where (organic) coating material is applied on a rolled metal strip in a continuous process including cleaning and chemical pretreatment of the metal surface and one-side or two-side, single or multiple application of liquid paints subsequently cured in ovens and finally rolled into coils.
COATING SYSTEMS
Depending on the applications, the coil coated steel flat products may be delivered with a specified organic coating in 2, 3 or 4-layers systems. The most frequently used coating systems are illustrated.
Primer, priming coat first coat of a multiple-coat system
Topcoat, finishing coat final (uppermost) coat of a multiple-coat system
Backcoat, backing coat coating of any type on reverse side with no particular requirements on appearance, corrosion protection, formability, etc.
Protective foil strippable plastic film applied to the coated surface in order to afford a temporary protection against mechanical damage
Primer
he primer's function is to give good intercoat adhesion between the substrate and topcoat. It also provides corrosion resistance to the overall coating system.
A variety of primers is available based on the application, requested appearance, environment, thickness, topcoat and overall functionality of final coating system.
The specific suitable primer to be used is recommended by specialists from paint producers.
The basic coatings differ:
chemical composition:
chrome-free
resin system/base:
polyester, polyurethane, epoxy, acrylic
applicable thickness:
low build (4-15µm), high build (up to 25-30µm)
physical properties:
viscosity, density, spreading rate
functionality:
flexibility, elasticity, hardness, corrosion resistance
appearance:
smooth, spray effect, orange peel effect
Topcoat
Topcoat is a coating applied on the primer and usually it is the uppermost coating of the coating system that is exposed to the surrounding environments. The function of the topcoat is to provide aesthetic and decorative appearance (color tone, gloss, texture, special effects) and/or corrosion protection.
There is a variety of topcoats available based on the application and environment intended for service, requested appearance, thickness and functionality of final coating system. The coating material used for topcoats comprises of organic polymers, pigments, additives and solvents which contribute to final properties of topcoat.
Topcoatings differ:
chemical composition:
chrome-free
resin system/base:
polyester, polyurethane, polyvinylidenfluorid, acrylic
applicable thickness:
interior (10-15µm), standard (20-25µm), high build (25-30µm)
physical properties:
viscosity, density, spreading rate, hiding power
functionality:
flexibility, elasticity, hardness, corrosion resistance
appearance:
color tone, gloss, smooth, textured, wrinkled or other effects
Backcoat
The main function of the backing coat is decorative, but it also provides a protection on the inside of the panel. In sandwich panels applications it has to provide good adhesion of insulation foams.
Backcoats are available for use with or without a primer. When applied as a single coat, its thickness is 8-12µm. Using primer increases the thickness and thus provides better corrosion resistance.
There is a variety of backcoats available based on the application, environment, requested appearance and functionality of the final product.
Backcoatings differ:
chemical composition:
chrome-free
resin system/base:
polyester, epoxy, polyurethane
applicable thickness:
single coat (8-12µm), with primer (>12µm)
physical properties:
decorative coloured coat, flexibility, corrosion protection, foam
functionality:
adhesion, anti-pressure marking, anti-fretting
appearance:
smooth, textured (high friction surface to prevent collapsing of coils), coloured options and gloss ranges
