The Viscosity Is High ,the Adhesive Strength Will Be Higher ?

Viscosity is an important parameter of adhesives, it reflects the strength of the interaction of liquid molecules in the process of movement, 

is used to measure the size of the viscosity of a physical data. The relative movement of the adjacent fluid layers when the fluid flows, and the frictional resistance between the two fluid layers is called the viscous resistance.

In simple terms, in adhesives, viscosity is a reference value that reflects whether the adhesive is thin or thick, usually the thicker the glue, 

the slower the fluidity, the greater the adhesive strength; On the contrary, the thinner the glue, the faster the fluidity, and correspondingly, 

the smaller the viscosity of the adhesive.

2.what is adhesive strength?

Adhesive strength, also known as bonding strength, is one of the important indexes to evaluate the quality of adhesives. 

Bonding strength refers to the stress required to destroy the interface between the adhesive and the adhesive in the adhesive part or its vicinity under 

the action of external force. In addition, according to the force in the use of adhesives, the bonding strength is usually subdivided into shear strength, tensile strength, peel strength and impact strength.

The size of the bonding strength depends not only on the bonding force, the mechanical properties of the adhesive, the nature of the adhesive, the bonding process, 

but also on the form of the joint, the force situation (type, size, direction, frequency), environmental factors (temperature, humidity, pressure, medium) and test conditions, experimental technology.

It is worth noting that the adhesive force is only one of the important factors that determine the strength of the bond, which is completely different from the two concepts of the bond strength and cannot be equated.
