A thixotropic adhesive does not really tell you anything about the adhesive viscosity. Ketchup is an example of a thixotropic fluid. But as you stir it, or dispense it for that matter, it will start to get more thin until you stop (with a delay). When the adhesive is not exposed to shear stress, it will stop flowing. Instead, it will maintain the shape it had when you dispensed it.
It also means that an adhesive that is thixotropic will not flow. In reality, this means that the viscosity is lowered more when the fluid is stirred for longer. What does it mean if an adhesive is thixotropic?Ī fluid is thixotropic when its viscosity is affected by movement (shear stress) and also is dependent of the time during which this movement takes place.
#HIGH VS LOW VISCOSITY MANUAL#
Adhesive viscosity is an important factor to consider when setting up your bonding process, regardless of whether it’s manual in a small scale or an automatic high-speed production. Viscosity is a concept which describes how a liquid material flows.
