Advanced Production Processes Lay the Foundation for Superior Products

Nosinda's prepainted aluminum coils utilize an internationally leading continuous high-speed roller coating process to ensure highly uniform and consistent coatings. Its core production processes include:

• Surface Pretreatment: Rigorous chemical cleaning and chroming processes thoroughly remove grease and dirt from the aluminum surface, forming a dense protective film that significantly enhances adhesion between the coating and the aluminum substrate and 
enhances corrosion resistance.

• Precision Coating: High-precision coating rollers are used to evenly transfer the coating to the aluminum coil surface under fully automated control. The company precisely controls coating thickness and uniformity to ensure that every meter of product meets standards.

• High-temperature curing: The coated aluminum coils enter a curing oven where the curing reaction proceeds under a defined temperature profile, resulting in a stable, long-lasting coating film.

Excellent Surface Coating: Fluorocarbon (PVDF) and Polyester (PE)

Nosinda offers two main surface coating options to meet different application environments and budgets:

• Fluorocarbon coating (PVDF): Utilizes a coating system containing at least 70% PVDF resin. Known for its excellent weather resistance, UV resistance, and self-cleaning properties, fluorocarbon coatings offer long-term resistance to harsh environments such as acid rain and salt spray, maintaining color fidelity for over 20 years. They are ideal for high-end architectural curtain walls and landmark projects.

• Polyester coating (PE): Polyester coatings offer excellent flexibility and adhesion, offering excellent cost-effectiveness. Available in a variety of finishes, including matte, pearlescent, and a wide range of colors. They also offer excellent weather resistance, making them suitable for most indoor and outdoor architectural decoration and home appliances.

Strict Quality Inspection System

Quality is the lifeblood of Nosinda. The company has established a comprehensive quality inspection system encompassing raw materials, production, and finished product delivery:

• Raw Material Inspection: The mechanical properties and chemical composition of the aluminum substrate are tested.

• Process Control: Key process parameters such as coating thickness, wet film viscosity, and baking temperature are monitored online.

• Performance Testing: Finished products undergo a series of laboratory tests, including adhesion (cross-hatch test), hardness (pencil hardness), impact resistance, solvent rub resistance, salt spray resistance (over 1000 hours), and UV accelerated aging testing, to ensure product performance meets or exceeds national standards (GB/T) and international standards such as ASTM.
