Driven by the in-depth advancement of China’s "Dual Carbon" strategy and increasingly stringent environmental regulations in recent years, the metal door and decorative door industries have accelerated the phase-out of highly polluting solvent-based coatings, making water-based baking coatings the mainstream solution for the industry’s green transformation. Against this backdrop, the water-based replacement of copper imitation door coatings has entered an advanced stage of technical research, shifting from the initial goal of "technical feasibility" to the core challenge of "achieving superior performance".
Industry Pain Points & Technical Difficulties
The coating process for copper imitation doors adopts a multi-layer composite coating system consisting of copper primer + wire-drawing coating + top clear coat. The multi-step process is complex with stringent inter-coat requirements, which further magnifies the inherent drawbacks of water-based systems. The industry is generally confronted with the following challenges:
1. The aqueous medium disrupts the alignment of pearlescent pigments in copper primers, resulting in insufficient metallic texture;
2. Water-based wire-drawing coatings suffer from poor wire-drawing performance, indistinct lines and weak adhesion;
3. Top clear coats deliver inadequate film fullness, poor substrate wetting and weak scratch adhesion when scraped by hand;
4. While securing reliable adhesion to various substrates and between coating layers, coatings must deliver significantly enhanced weather resistance and corrosion resistance to withstand harsh outdoor and semi-outdoor environments such as residential entrance doors, commercial buildings and villa courtyards.
Targeted Solutions
To address the above pain points, Huaguoshan has optimized the molecular structure of base resins and drawn on extensive application data to launch a proprietary golden combination system:
Copper Primer Houxian® 5954K + 5017K (delivering exceptional copper pigment alignment and intense metallic luster), matched with solvent-based wire-drawing coating for distinct layered textures, and top-coated with matte clear coat Houxian® 1169 (offering smooth, transparent and full film finish). This three-layer tailored coating system provides an all-in-one solution to resolve bottlenecks in matched baking coatings for copper imitation doors.
Step 1: Copper Primer — Houxian® 5954K + 5017K
Scientific blending of the two resins balances pigment orientation, compatibility, adhesion, drying speed and comprehensive chemical resistance, forming the core raw material for high-end copper powder coatings.
