Construction Coil Coating
Application:
The main use of these metal sheets is in the building facade, sandwich panels and use in the roof and attics.
Product Introduction:
The physical-mechanical features of the coating of metal coils, whether aluminum or galvanized, allow the sheet to be painted first and be provided to industries as a coil or pre-painted sheet. These sheets have the ability to withstand the change of mechanical forms, including cutting, bending, stretching, and in these stages, they maintain their adhesion to their substrate. In addition, these coatings have very good weather resistance and are suitable for structures that are exposed to sunlight and different weather conditions (sultry, desert, urban). These coatings are applied by roller method and are often applied in three layers of lining, top and back coating on the sheet.
Technical Specifications:
This coating is applied on the metal surface in the form of 3 top layers, primer and back coating.
* Primer layer: This layer is implemented with the aim of improving the adhesion and flexibility of the coating system. Its formulation requirements include high adhesion, high flexibility and longer curing time than the top layer. After applying the primer and placing the galvanized sheet in the furnace, this layer should not be fully baked; Because if this happens, the top layer will not stick to it.
* Top layer: This layer is the most important layer and its formulation is very important. This layer contains polyester resin, pigment, hardening agent and catalyst.
* Back coating: This layer is 5 micrometers thick on the back of the galvanized sheet and is based on polyester resin or a hybrid of epoxy and polyester. The back layer is connected with a single layer of foam, usually made of polyurethane, and the adhesion of this layer to polyurethane foam is one of the requirements of this layer.
Advantages:
This company currently supplies 50% of the steel industry’s needs, which is a proof of its high production capacity and reasonable price. Another advantage of this company is the completeness of its product portfolio.
