Polyurethane Adhesive
The Ideal Choice for Metal Bonding and Sealing
Our polyurethane adhesive is specially designed for metal applications, delivering exceptional bonding performance and long-lasting durability.
Applications of Polyurethane Adhesive
Metal Component Bonding
Structural Bonding: During manufacturing and assembly, polyurethane adhesive effectively bonds different types of metals, such as aluminum, steel, stainless steel, and copper, forming strong joints. It can replace traditional welding and riveting methods, reducing the risk of thermal stress and deformation.
Multi-Material Bonding:When there is a need to bond metal with non-metal materials like plastic, wood, or glass, polyurethane adhesive offers excellent cross-material bonding performance, ensuring stable connections between different materials.
Metal Repair and Protection
Crack Repair:For cracks and damages on metal surfaces, polyurethane adhesive can penetrate and fill the cracks, providing long-term repair. Its flexibility and fatigue resistance ensure outstanding performance even under dynamic loads.
Anti-Corrosion Coating: Polyurethane adhesive can also be used for anti-corrosion treatment on metal surfaces, forming a protective coating that resists moisture, chemicals, and environmental factors, thereby extending the service life of metal components.

Waterproof Sealing
Metal Joint Sealing: In applications such as metal roofs, walls, or pipelines, polyurethane adhesive offers superior waterproof sealing. It can effectively fill joints, prevent moisture infiltration, and maintain the waterproof integrity of the structure.
Insulation and Protection: Polyurethane adhesive also has good electrical insulation properties, making it suitable for sealing and protecting metal components in electrical equipment, preventing the intrusion of moisture and corrosive substances.
Advantages of Polyurethane Adhesive
Outstanding Weather and Corrosion Resistance
UV Resistance: Polyurethane adhesive resists long-term UV exposure, without degrading or failing due to sunlight, making it suitable for outdoor metal bonding and sealing applications.
Chemical Corrosion Resistance: Its chemical resistance enables the adhesive to maintain stable bonding performance in environments with exposure to various oils, acids, alkalis, and solvents, making it ideal for corrosive environments such as chemical, marine, and heavy industries.
Superior Bonding Strength
High-Strength Bonding: Polyurethane adhesive forms a strong bond on metal surfaces, with excellent shear and tensile strength. It maintains stable bonding performance even in high-load or complex stress environments.
Long-Lasting Durability: Its polymer structure ensures that the adhesive remains durable after curing, maintaining a strong bond over long-term use.
Excellent Flexibility and Impact Resistance
Stress Concentration Resistance: Once cured, polyurethane adhesive retains some flexibility, allowing it to accommodate slight deformations in metal caused by temperature changes or mechanical stress, preventing bond failure due to stress concentration.
Impact and Vibration Resistance: Its high impact resistance allows it to absorb and disperse forces from impacts or vibrations, protecting the integrity of the metal structure.
Easy Application
Simple Operation: The formulation of polyurethane adhesive makes it easy to apply and handle during construction, with good flowability and self-leveling properties, allowing it to quickly cover large metal surfaces.
Fast Curing: The adhesive has a short curing time, quickly reaching its usable strength, reducing construction time, and improving efficiency.
Environmental and Safety Benefits
Low VOC Emissions: Our polyurethane adhesive features an environmentally friendly formulation with low VOC emissions, meeting strict environmental standards and reducing the impact on workers and the environment.
Safe and Non-Toxic: Once cured, the adhesive is non-toxic and odorless, making it suitable for applications with high health and safety requirements, such as bonding metal components in food processing equipment and medical devices.
