Melt viscosity of hot melt adhesive

The melt viscosity of hot melt adhesive is one of the conventional indicators, and its importance directly affects the choice of hot melt adhesive construction technology. The use of hot-melt adhesive must use a heating device to turn the solid hot-melt adhesive into a liquid state. Different industries, different uses, have different physical properties, glue equipment and methods of sizing.

 The different sizing methods determine the different melt viscosity that the hot melt adhesive should have. The common methods of using glue include spraying, dotting, spraying, rolling, and scraping. Generally, the required melt viscosity is from low to high. . The melt viscosity of the hot melt adhesive is not necessarily related to the adhesion and bonding ability. It cannot be considered that the melt viscosity is high and the viscosity is good, and it should be related to its fluidity.
