The ability of a gel to become less viscous (resistance to flow) under pressure then thicken when pressure is released.
A term describing the rehology (or flow characteristics) of a liquid that resists flowing or drainage during application.
Paints that are jelly-like until stirred or applied, at which point they become liquid.
Pseudoplastic flow that is time-dependent. At constant applied shear rate, viscosity gradually decreases.
Describes solder creams which have a high viscosity at zero or low shear rates and decreased viscosity at higher shear rates.
A quality of some resins to thicken at rest but become fluid again on agitation and stirring. Thixotropic resins are used in boat work to minimize runs and sags on vertical surfaces.
A property of materials which are quite thick while standing and become thinner when agitated.
A consistency that is gel-like at rest, but fluid when agitated. Having high static shear strength and low dynamic shear strength simultaneously. Losing viscosity under stress.
The characteristic of certain gels, such as shear-thinning MR-fluid formulations, that causes the gels to become fluid when shaken or stirred, and return to a semisolid state upon standing. This characteristic mitigates gravitational settling.
Non-slump or sag property, no flow without pressure
A characteristic of some fluids where they become temporarily less viscous when agitated; some mediums used in oil painting are thixotropic, including Maroger's medium.
Adjective which describes full-bodied material which undergoes a reduction in viscosity when shaken, stirred, or otherwise mechanically disturbed and which readily recovers the full-bodied condition on standing.
Concerning materials that are "gel-like" at rest but that are fluid when agitated. Materials having high static shear strength and low dynamic shear strength at the same time.
fluids which change viscosity when subjected to shear forces over time, so that the more they are made to flow, the less resistance to flow they have
The property of a fluid whose viscosity decreases with time (see Appendix A).
An adjective which describes full bodied material that undergoes a reduction in viscosity when shaken, stirred or otherwise mechanically disturbed but readily recovers its original full bodied condition upon standing.
A material with paste-like consistency at rest but flows under pressure or agitation (e.g. cold cream or grease).
A material flow behavior where there is a yield strength that must be overcome to initiate flow and with shear the viscosity decreases; however, during aging weak bonds form to increase viscosity.
The property of a material that enables it to stiffen in a short time while at rest, but to acquire a lower viscosity when mechanically agitated, the process being reversible. Grouts having thixotropic properties can be highly resistant to bleed. Admixutres that may produce thixotropic properties include anti-bleed admixtures and silica fume.
Nonsagging. A material which maintains its shape unless agitated. A thixotropic sealant can be placed in a joint in a vertical wall and will maintain its shape without sagging during the curing process.
Concerning materials that are gel-like at rest, but fluid when agitated. Having high static shear strength at the same time. To lose viscosity under stress.
Said of materials that are gel-like at rest but fluid when agitated. Liquids containing suspended solids are apt to be tixotropic. Thixotropy is desirable in paints.
A full-bodied material which undergoes a reduction in body when shaken, stirred or otherwise mechanically disturbed and which readily recovers the original full-bodied condition on standing. In screen printing the work applied by the action of the flood coater or squeegee is sufficient to allow the ink to flow through the mesh.
having the property of decreasing viscosity with increasing shear stress. A coating is thixotropic if it thins with stirring or pumping but thickens when movement ceases.
Describes materials that will not flow unless agitated or forced through an orifice. Shear thinning.
