Exploring the Coating Structure of UV Vacuum Plating

Exploring the Coating Structure of UV Vacuum Plating

The coating system produced by UV vacuum plating on non-metallic substrates such as plastics employs a multilayer architecture. This structure comprises a primer layer, a deposition layer, and a topcoat layer, with an intermediate layer sometimes added to meet more stringent performance requirements. Each layer is tailored in composition and function, working in concert to form a comprehensive performance chain that extends from the substrate to the surface. Understanding the structural characteristics and functional roles of each layer is fundamental to grasping the underlying principles of UV vacuum plating technology.

Analysis of the Core Components of UV Vacuum Plating

Analysis of the Core Components of UV Vacuum Plating

The UV vacuum plating process can impart a metallic finish to non-metallic substrates such as plastics, with its superior performance stemming from the synergistic interactions among the components of the coating system. This system comprises three key layers—primer, plating material, and topcoat—each fulfilling distinct functional roles. The primer ensures adhesion and surface leveling, the plating material delivers the metallic luster, and the topcoat provides protection and decorative appeal. A thorough understanding of the composition and underlying mechanisms of these core components is essential for grasping the fundamental principles of UV vacuum plating technology.

Testing Items for UV Vacuum Plating Performance (Part II)

Testing Items for UV Vacuum Plating Performance (Part II)

The chemical properties of UV vacuum‑plated coating systems determine their stability and durability under a wide range of environmental conditions. Unlike physical‑property testing, which focuses on surface appearance and mechanical strength, chemical‑property evaluation places greater emphasis on the molecular‑level structural characteristics of the coating material and its responsiveness to external chemical environments. From resistance to chemical corrosion and aging degradation to assessing the degree of coating cure and interfacial chemical stability, these chemical parameters serve as critical criteria for evaluating product quality and predicting service life. This paper outlines the principal chemical‑property test items and methodologies for UV vacuum plating, examining four key aspects: chemical resistance, weathering resistance, degree of cure, and surface chemical characteristics.

Test Items for UV Vacuum Plating Performance (I)

The coating system formed by UV vacuum plating on non-metallic substrates such as plastics has physical properties that directly determine the product’s performance and service life. From optical appearance to mechanical strength, and from surface morphology to environmental resistance, the evaluation of these physical parameters serves as a critical basis for verifying product quality and optimizing process parameters. Systematic testing of physical properties enables assessment of whether the deposited film meets design specifications, providing scientific support for quality control during production. This paper outlines the key physical‑property test items and methods for UV vacuum plating, focusing on four aspects: optical performance, mechanical performance, surface morphology, and durability.
