。Common hot melt adhesives are physically cured and do not involve chemical reactions. They generally include hot melt resins such as ethylene vinyl acetate (EVA), polyester, polyamide, etc. With the development of materials science in recent years, PUR hot melt adhesive has further developed, resulting in the emergence of moisture reactive polyurethane hot melt adhesive.

What are the advantages of PUR hot melt adhesive compared to regular hot melt adhesive? Compared with ordinary hot melt adhesives such as EVA hot melt adhesive and water-based/solvent based adhesives, PUR hot melt adhesive has the following advantages:


1. PUR hot melt adhesive is a solvent-free adhesive that does not require a drying process like solvent based adhesives, and does not cause environmental pollution or poisoning problems. It is a green and environmentally friendly product.


2. PUR hot melt adhesive, easy to operate. Two adhesives can be fixed in a short period of time without drying, improving efficiency and saving time.


3. PUR hot melt adhesive has excellent heat resistance, cold resistance, water vapor resistance, chemical resistance, and solvent resistance. Due to the irreversible nature of PUR adhesive once it reacts (i.e. it will not melt even when heated), the coated wire board can remain stable at -40 ° C to 150 ° C, resulting in more stable product quality.


4. In the custom furniture industry, PUR glue is currently mainly used for edge sealing of decorative panels. In the application of edge sealing, the quality and product performance of PUR glue are better than EVA glue. In the application of flat pasting, PUR glue has good adhesion with most boards, is easy to roll apply, and can be continuously produced, which makes it increasingly used in the production of decorative panels.

5. PUR hot melt edge sealing adhesive can not only improve the paint resistance of wood veneer processing in the production of wood panel furniture, but also cause the edge sealing material to fall off due to the high temperature resistance of the adhesive layer after traditional hot melt adhesive edge sealing and hot pressing veneer operation. Therefore, the traditional hot melt adhesive edge sealing technology determines that the production of wood veneer can only adopt the process of veneer first and then edge sealing, which inevitably leads to the production of adhesive seams after edge sealing and reduces the product grade. However, using high-temperature resistant PUR hot melt adhesive for edge sealing efficiently solves this problem. In addition, the process of PUR edge banding adhesive getting wet is also irreversible. The use of PUR edge banding technology can effectively improve the quality and service life of high-end interior furniture products such as bathroom cabinets, cabinets, solid wood furniture, and office furniture.
