Car Paints:
The phosphate coating, a conversional layer, serves two primary purposes:
- Prevention of framework corrosion.
- Creation of a layer for enhanced adhesion of Electro Deposition (ED).
In the phosphate process, metal substrates such as iron, steel, galvanized, and aluminum undergo a transformation into a thin and uniform insoluble phosphate layer to resist corrosion and abrasion. The weight and structure of the phosphate layer are meticulously controlled by factors such as time, heat, type of dilution, and surface cleaning method before coating. This process initiates the initial stage of automobile frame coating. The degreasing and phosphate substances from our company not only provide robust degreasing for Cold Rolled Steel (CRS) and galvanized sheets but also establish an excellent phosphate layer.
Before the phosphate process, the automobile framework undergoes a degreasing stage. Our company’s degreasing products, based on alkali ingredients, are typically applied through manual methods (cleaning with napkins), splashing, and dipping to eliminate pollution particles like oil and grease from the metal surface. After alkali degreasing, the automobile frame is rinsed, marking the commencement of the phosphate process. This process encompasses three main stages: activation, phosphatization, and passivation.
Electrodeposition (ED) represents a chemical treatment painting method where electrical conduction directs water-based paint into positive and negative ions within a tank. The automotive frame, possessing opposite conductivity, enters the tank, and the paint adheres to it. While the immersion method has historical significance in industrial coating for approximately a century, advancements have led to more sophisticated immersion techniques. The electrical immersion method, introduced in the automotive manufacturing industry for primer layers around 1960, has evolved and is now recognized as an eco-friendly painting method.
Key advantages of the electric immersion method include film smoothness, superior appearance and quality, comprehensive coverage for complex substrates, the potential for mass production in syndetic applications, low waste percentage, minimal volatile content loss, and a negligible reduction in fire risks within the coating process. This method is particularly employed to protect components with high resistance to atmospheric corrosion. Although primarily used for primer layers, in some instances, it is also applied for a single-layer coating. While the basic principles of this method are straightforward, its operation often involves numerous complexities.
Electrical immersion painting is categorized into two types: cathodic method and anodic method. Both involve creating a smooth electrical flow in the existing water-based color in the immersion tank, a phenomenon known as Electrophoresis. The applicable water-based paint, consisting of resin, solvent, pigments, water, and additives, carries a negative charge in the anode method (AED) and a positive charge in the cathode method (CED). After application to the surface, a soft and undissolved coating forms, gradually solidifying. Presently, the CED products of this company are produced under the supervision of BASF and NOROO companies, adhering to high-quality standards set by car manufacturers.
Underbody insulation for a car’s chassis is manufactured using polyvinyl chloride polymer. This product serves to shield the vehicle’s body from environmental elements such as water, pebbles, mud, etc. After undergoing a baking process in the furnace, the product transforms into a protective barrier layer, providing both protection and soundproofing effects.
The sealant is a blend based on polyvinyl chloride polymer, extruded to fill pores and seams in the car frame, particularly focusing on two-piece welding sites.
Key advantages of this product include excellent resistance to environmental conditions, absence of sedimentation, optimal flow ability in transfer pipes, uniformity, particle-free composition, low viscosity variations during storage, and a drip-free characteristic.
