is a type of adhesive known for its exceptional bonding strength and versatility. Here’s a breakdown of its characteristics and common uses:
- Composition: PUR stands for Polyurethane Reactive adhesive. Unlike traditional adhesives like PVA (polyvinyl acetate) glue, PUR adhesive cures through a chemical reaction with moisture in the air. This reaction creates a strong, durable bond that is resistant to moisture, heat, and chemicals.
- Bonding Strength: PUR adhesive is prized for its high bonding strength, making it suitable for a wide range of materials, including wood, plastics, metals, glass, and composites. It creates a bond that is often stronger than the materials being joined.
- Versatility: PUR adhesive is used in various industries and applications, including woodworking, cabinetry, furniture manufacturing, automotive assembly, aerospace, and construction. It can bond both porous and non-porous materials, making it highly versatile.
- Application: PUR adhesive is typically applied using specialized dispensing equipment, such as hot melt glue guns or adhesive applicators. The adhesive is dispensed as a liquid or semi-liquid and cures rapidly upon exposure to air moisture, forming a strong bond within minutes.
