Under ideal storage conditions, the shelf life of industrial hot melt glue can be up to two to three years. Many manufacturers usually indicate the best use date of their products on the packaging, and this date is usually determined based on laboratory test results and long-term tracking of the performance of industrial hot melt glue.

Industrial hot melt glue is widely used in the manufacturing and packaging industries of paper products. It can quickly bond paper and cardboard to form a strong bond. Especially in the packaging industry, industrial hot melt glue can quickly seal cartons, label stickers.

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
