PUR hot melt adhesive

PUR reactive hot melt adhesive is a moisture-reactive adhesive characterized by its 100% solid content and solvent-free formulation. It is composed of isocyanate (NCO) terminated polyurethane prepolymers that cure by reacting with moisture in the air, forming a robust adhesive structure. This adhesive remains solid at room temperature and melts quickly when heated to moderate temperatures. Upon cooling, it undergoes a chemical reaction with moisture, ultimately resulting in a high-strength bond.

Features of PUR Hot Melt Adhesive

• Environmentally Friendly and Solvent-Free: PUR adhesives do not contain volatile organic compounds (VOCs), making them environmentally friendly.

• High Initial Strength: They can rapidly form a strong bond, making them suitable for fast-paced production environments.

• Wash and Chemical Resistance: PUR adhesives are designed to withstand various environmental conditions, ensuring long-term stability.

• Good Thermal and Cold Resistance: They are applicable in a wide range of climatic conditions, providing reliable performance.

Applications of PUR Reactive Hot Melt Adhesive

PUR reactive hot melt adhesives are widely used across various industries, including:

• Textiles: Used for bonding and laminating fabrics, fibers, and other composite materials.

• Footwear: Ideal for adhering rubber, synthetic leather, and other components of footwear, meeting environmental standards.

• Electronics: Employed in the assembly, sealing, and protection of electronic components.

• Medical Supplies: Suitable for laminating surgical gowns, bed linens, and other medical products.

• Construction and Furniture: Utilized in woodworking and furniture assembly, providing stable structural support.

Overall, PUR reactive hot melt adhesives offer a versatile and effective bonding solution for a variety of applications, combining environmental benefits with high performance and durability.
