Strong Adhesion UV Metal Adhesion Resin Rapid Curing

Key Technological Highlights

1. UV High-Functionality Resin

   • Utilizes high-functionality monomers and prepolymers to significantly increase crosslinking density, forming a dense and tough cured film that enhances both chemical bonding and physical anchoring with metal surfaces.

2. UV Yellowing-Resistant Resin

   • Designed with an aliphatic molecular structure to prevent photoxidation reactions from aromatic components, maintaining pure color even under prolonged UV exposure or high-temperature conditions, making it ideal for light-colored or transparent coatings.

3. UV Water-Resistant Resin

   • Incorporates hydrophobic functional groups and a dense crosslinking network to effectively block moisture penetration, preventing metal substrate corrosion and coating bubbling or peeling—perfect for humid or outdoor applications.

Core Properties & Advantages

• UV Strong Metal Adhesion Resin: Utilizes polar group-directed adsorption and interface reinforcement technology, achieving 5B adhesion rating (ASTM D3359) on metal substrates, solving traditional coating delamination issues.
• UV Fast-Curing Resin: Supports LED-UV light source for second-level curing, compatible with high-speed production lines, significantly improving processing efficiency and reducing energy consumption.
• UV High-Transparency Resin: Light transmittance >95% (400-800nm), ensuring no color interference with plated layers, perfectly showcasing metal textures and fine details.
• UV High-Gloss Resin: Forms a mirror-smooth surface after curing, achieving a 60° gloss level of >120 GU, enhancing the high-end visual appeal of products.
• UV Low-VOC Resin: Solvent-free formulation with VOC content <50ppm, compliant with EU REACH and China GB/T 38597 environmental regulations.
• UV High-Strength Film-Forming Resin: Hardness up to 4H (pencil hardness), impact resistance >50kg·cm, offering excellent wear resistance and durability.
• LED Optimized Surface Cure Resin: Enhanced photoinitiator system prevents oxygen inhibition, ensuring fast, non-tacky surface curing under LED light.

Typical Application Scenarios

• Consumer Electronics: Metal phone frames, laptop casings, smartwatch housings—balancing lightweight design with scratch resistance.
• Automotive Components: Wheel hub covers, door handles, interior metal trims—featuring excellent weather and chemical resistance.
• Household Hardware: Stainless steel kitchenware, bathroom faucets, metal lighting fixtures—providing high-gloss protection and easy-to-clean functionality.
• Industrial Equipment: Precision instrument casings, metal nameplates—meeting high-strength, corrosion-resistant, and long-term outdoor use requirements.

Working Principle

UV metal adhesion resin achieves high-efficiency bonding through the following steps:

1. Surface Preparation: The metal surface is cleaned and treated to remove grease, oxides, and other impurities, ensuring optimal adhesion.
2. Resin Coating: The UV metal adhesion resin is evenly applied to the metal surface using spraying, brushing, or dipping methods.
3. UV Curing: The coated resin is exposed to UV light, enabling rapid curing and forming a strong adhesive layer.
4. Post-Treatment: Additional processes such as polishing, coloring, or applying protective coatings can be performed as needed to enhance performance and aesthetics.
