At present, hot melt adhesive is mainly used in furniture manufacturing industry, including flat paste, cladding, edge sealing. Here is a brief introduction of the advantages and disadvantages of PUR hot melt adhesive:
As a reactive polyurethane adhesive, the main reaction of PUR hot melt adhesive is to react with moisture or curing agent. First, let's share its corresponding advantages:
1. Compared with the traditional EVA hot melt adhesive, its bonding performance, high and low temperature resistance, weather resistance, solvent resistance and so on are more excellent.
2. Due to the strong permeability of PUR hot melt adhesive, it can be bonded to a wider range of substrates than traditional EVA hot melt adhesive.
3. Due to its excellent bonding ability and coatability, the amount of adhesive is about 2/3 less than that of traditional EVA hot melt adhesive.
4.PUR solid content can reach 100%, green and safe after curing.
Having said the advantages of PUR hot melt adhesive, let's talk about its corresponding disadvantages:
1. Compared with the traditional EVA hot melt adhesive, the gluing equipment needs to invest more funds to upgrade to professional equipment.
2. The humidity and temperature of the environment require more suitable curing conditions.
3. There is no reversible condition after the product is cured, and it is more difficult to clean the equipment than traditional EVA hot melt adhesive.
4. The unit price of the product is several times higher than that of EVA hot melt adhesive, but this shortcoming can be ignored due to its small amount of glue.
The above are the advantages and disadvantages of PUR hot melt adhesive, I hope it will be helpful for you to understand PUR hot melt adhesive!
