Comparison of water-based adhesive, solvent adhesive, and hot melt adhesive

2021/05/10

Water-based glue: Water-based glue has a small smell, is not flammable, and is easy to clean. However, various additives are added to the water-based glue, which will cause certain pollution to the environment. In addition, the water-based adhesive has long curing time, poor initial viscosity, poor water resistance, and poor low temperature resistance.

Solvent glue: strong viscosity, not easy to overflow, suitable for outdoor labeling, but solvent glue is not environmentally friendly. Solvent glue contains raw materials that are harmful to health, such as toluene and xylene. Therefore, solvent glue is toxic and dangerous. Solvent glue has certain risks in the production process and transportation process, and the price of such products is relatively high.

Hot-melt adhesive: Hot-melt adhesive has strong viscosity, good water resistance, and it is a blocky solid at room temperature. Even with prolonged contact, hot melt adhesive will not harm the human body. It is green and environmentally friendly and reproducible, and meets the requirements of international environmental protection agencies. This is the unparalleled superiority of other adhesives.

In summary, hot melt adhesives are the most environmentally friendly. During use, hot melt adhesives hardly release by-products and will not cause adverse effects on the environment. Therefore, hot melt adhesive is the safest adhesive in industrial production. It has become a trend to replace other glues with hot melt adhesives.
