The curing time of PUR hot melt glue is generally divided into initial curing time (about 15 seconds to 1 minute) and full curing time (usually 24 hours). Within 24 hours, PUR hot melt glue can fully cure and reach its maximum bonding strength, but this also depends environmental conditions and adhesive type.

The five most suitable uses for industrial hot melt glue: 1. Packaging industry 2. Woodworking industry 3. Electronics industry 4. Automobile industry 5. Textile and footwear industry Choose EVA hot melt glue for applications that require fast curing and low cost, and pur hot melt glue is more suitable for applications that require high bonding strength and temperature resistance.

Advantages of hot melt glue: 1. Fast curing, improving production efficiency 2. No solvent components, environmentally friendly and pollution-free 3. High bonding strength 4. No additional drying time required 5. Good operability and adaptability Disadvantages of hot melt glue: 1. Limited strength and heat resistance 2. Poor moisture resistance 3. Poor bonding effect on some materials 4. Brittle and poor impact resistance 5. Poor aging resistance 6. High construction environment requirements

EVA hot glue vs. PUR hot glue: 5 major differences 1. Differences in chemical composition and curing mechanism 2. Differences in bonding strength and flexibility 3. Differences in weather resistance and durability 4. Differences in construction methods and equipment requirements 5. Differences in storage and stability

PUR stands for "polyurethane" and has excellent mechanical properties and chemical stability. PUR industrial hot glue is a special application form of polyurethane material. It is heated and melted into a liquid state, and then applied to the surface to be bonded.

PVC Waterproof Sealing Strip is a sealing strip specially designed for waterproof applications with higher waterproof standards. Compared with ordinary PVC sealing strips, PVC Waterproof Sealing Strip usually adopts a more sophisticated production process to ensure a stronger sealing effect and more durable waterproof performance.
