Structural Adhesives Frequently Asked Questions

Viscosity is a number that you see on data sheets but it doesn't really characterize the adhesive – that's why it can be confusing These adhesives are non-Newtonian in their behavior which simply means that their apparent viscosity or how they flow depends on the shear stress that you apply to them Get price


Apparent viscosity

Apparent viscosity (sometimes denoted η) is the shear stress applied to a fluid divided by the shear rate (= ˙) For a Newtonian fluid the apparent viscosity is constant and equal to the Newtonian viscosity of the fluid but for non-Newtonian fluids the apparent viscosity depends on the shear rate Get price


Shear stress

The shear stress of a — shear stress is not proportional to the rate of shear A non-Newtonian fluid may be said to have an apparent viscosity a viscosity that holds only for the shear rate (and temperature) at which the viscosity is determined Back to Glossary Index Quickly identify equipment-specific issues Bureau Veritas Get price
