Polyurethane Adhesive Series
In addition, the polyurethane adhesive series places great emphasis on environmental protection and sustainable development. Some of its products feature low-VOC (volatile organic compound) formulations, which significantly reduce environmental pollution and meet the modern industrial demand for green production. As technology continues to advance and the market expands steadily, the polyurethane adhesive series is constantly innovating and evolving. It not only reinforces its position in traditional application areas but also demonstrates promising potential in emerging fields such as new-energy vehicles and electronic information, thereby making a significant contribution to the development of these related industries.

Detailed information
Core advantages
- Balanced bonding performance: It provides stable adhesion to a wide variety of materials, including metals, wood, plastics, rubber, fabrics, and more, eliminating the need to frequently switch adhesive types depending on the substrate. It boasts broad compatibility. The adhesive layer formed on material surfaces exhibits strong bonding and is unlikely to peel off even under slight vibrations or temperature fluctuations.
- Good elasticity and toughness: After curing, the material exhibits a certain degree of elasticity, enabling it to accommodate thermal expansion and contraction, deformation, and mechanical stresses of the bonded substrate, thereby reducing bond failure caused by differences in material expansion and contraction. When subjected to external impact, its inherent toughness can absorb and dissipate energy, lowering the risk of damage to the bonded joint.
- Stable environmental performance: The product maintains consistent performance under typical temperature and humidity conditions. Certain specially formulated products can withstand moderate levels of acid and alkali corrosion, immersion in moisture, and exposure to ultraviolet radiation, making them suitable for a wide range of indoor and outdoor applications.
- Strong construction adaptability: Available in various formulations—including solvent-based, water-based, and solvent-free—allowing you to select different application methods such as brushing, spraying, or spot coating based on your specific construction needs. Some products offer adjustable curing speeds, meeting both the high-efficiency demands of mass production and the precise operational pace required for fine craftsmanship.
- Tunable mechanical properties: By adjusting the formulation ingredients, it is possible to achieve a range of mechanical properties—from soft and elastic to hard and high-strength—thus meeting the specific requirements for adhesive hardness and strength in different applications.
Highlight advantages
- Excellent interfacial bonding mechanism: Not only does it rely on surface adhesion, but certain components can also undergo chemical reactions with the active functional groups on the substrate surface, creating a synergistic effect of both chemical bonding and physical adsorption. As a result, its bonding stability surpasses that of adhesives relying solely on a single bonding mechanism.
- Compatible with a variety of process requirements: It can be integrated with automated gluing equipment to enable continuous production; it can also meet the needs of small-batch operations such as manual repairs, making it versatile for both large-scale industrial production and sporadic repair scenarios.
- Continuously improving environmental friendliness: The technology for solvent-free and high-solids-content waterborne polyurethane adhesives is becoming increasingly mature, effectively reducing the emission of volatile organic compounds. This aligns with current environmental policies across various industries and further expands their scope of application.
- Guaranteed service life: Under conditions of reasonable use and routine maintenance, its bonding performance degrades slowly, providing long-term, stable structural support for the bonded products and reducing costs associated with product repairs or replacements caused by adhesive aging.
Main application scenarios
1. Architecture and Interior Design Industry
It is used for bonding various types of boards, such as wood-plastic boards, gypsum boards, and insulation boards, for joining them together and securing them to walls. In window and door installation, it ensures a tight bond between profiles, glass, and sealing strips, enhancing the sealing performance and thermal insulation of windows and doors. It can also be applied to the installation of stone and tiles, particularly suitable for areas prone to stress, such as wall corners and floor joints, thereby reducing issues like hollowing and detachment.
2. Automotive Manufacturing Industry
Bonding applications for automotive body components—such as the connection between door inner and outer panels, and between the roof and the vehicle frame—both reduce vehicle weight and enhance structural strength. In automotive interiors, it is used to secure dashboards, seat upholstery, and door trim pieces; its elasticity helps cushion vibrations during driving, thereby improving the durability of interior components. It can also be used for sealing and bonding headlights, preventing moisture from seeping in and compromising lighting performance.
3. Furniture and Woodworking Industry
It is one of the core adhesives used in the production of solid wood furniture and panel furniture, employed for joining wood pieces, reinforcing mortise-and-tenon joints, and bonding veneer sheets to board surfaces. After bonding, it leaves no visible glue lines, enhancing the aesthetic appeal and texture of the furniture. It can also be used in the processing of bamboo and rattan products, perfectly accommodating the natural flexibility of these materials and preventing cracks or fractures at the bonded areas.
4. Packaging and Printing Industry
Suitable for the production of various composite packaging materials, such as the lamination of plastic films with aluminum foil and paper, creating packaging materials that combine barrier properties and toughness, ideal for packaging food, pharmaceuticals, and other products. In the binding of printed materials, certain specialized polyurethane adhesives can be used to achieve perfect wire-o binding for books and photo albums, providing strong adhesion and smooth page-turning.
5. Electronics and Electrical Appliances Industry
It is used for encapsulating and securing electronic components—for example, bonding components onto circuit boards and sealing battery assemblies. Its stable insulation performance and temperature resistance can protect electronic components from environmental influences. In the assembly of electrical appliance housings, it enables a tight bond between plastic housings and metal fittings, thereby enhancing the overall structural stability of the appliance.
6. Textile and Leather Industry
For leather goods processing—such as bonding the upper and sole of leather shoes or splicing leather bag fabrics—the adhesive ensures flexibility to accommodate the leather’s natural bending and deformation, and is resistant to delamination. In the textile industry, it can be used for laminating fabric layers—for example, bonding the fleece lining to the base layer in thermal underwear or adhering waterproof coatings to fabric in outdoor apparel—thereby enhancing the functionality of garments.
