Density：Density reflects the amount of solid content in the adhesive.

1. Unit

The mass of a substance per unit volume. The international unit is kg/m³, and the commonly used unit is g/ml.

2. Measurement and significance of density

Method: density cup, 5ml syringe (reference method).

Significance: physical constant, no special significance in electronic adhesives.

Viscosity：The internal friction between molecules when a liquid flows is called viscosity, and viscosity indicates the viscosity, which is an important property of adhesives.

 1. Dynamic viscosity

Two plates with an area of 1㎡ and a distance of 1 meter are added with a shear stress of 1N to make the relative velocity 1m/s, and the viscosity is 1Pa.s. The commonly used unit is Pa.s.

2. Kinematic viscosity

The ratio of dynamic viscosity to density at the same temperature indicates the internal friction of a liquid when it flows under gravity. The unit is ㎡/s.
