People always feel that a thicker glue will stick better than a thinner glue. They say that a thinner glue will not stick like water. Is that actually true? The hot melt adhesive thin consistency is directly related to the viscosity?

We randomly selected different brands of hot melt adhesive from the market to test. Heated at high temperatures, these hot melts into liquid glue, of course, their consistency is very different. We tried to apply the glue on the same material to test their respective bonding effect. In order to ensure the reference of the test results, we made the application environment of each type of glue consistent and the bonding material same, except for the hot melt adhesive. After a series of instrument test and verification, the result is: hot melt adhesive as a single individual, its thin consistency and viscosity does not have a direct relationship! No matter how thin consistency of hot melt adhesive may also have the same viscosity, but the actual application of the adhesive effect can not fully represent its real viscosity properties.

Viscosity and thin consistency are the representation of the properties of hot melt adhesives, which have reference value for the applicability of different adhesive applications. The relationship between them can only be reflected in the composition of hot melt adhesives. The physical values of viscosity and consistency may increase or decrease as the proportion of one component increases or decreases, but that alone does not tell us anything. They are only the individual parameters of the hot melt adhesive, only in the parameter comparison can reveal its true value. If you're not actually using it, it's just a set of numbers.

To tangle the relationship between the viscosity of hot melt adhesive and its thin consistency, if you encounter bonding problems, the top priority is to find out the problem as soon as possible. Again, a very thin glue can be very sticky, and a very thick glue may not stick well.
