What is the thixotropic agent?
Thixotropic agents are added to give the paint the correct rheologic properties such as viscosity and sag resistance (sagging is defined as the downward movement of a paint film on a vertical surface during curing, resulting in an uneven coating having a thick lower edge) and to prevent settling of the pigments during …
What is meant by thixotropic?
Definition of thixotropy : the property of various gels of becoming fluid when disturbed (as by shaking) … says that blood liquefaction can be explained in terms of a phenomenon called thixotropy.
What is thixotropic example?
Examples of thixotropic materials include many gels and colloids, as well as common food products such as ketchup and yogurt. However, thixotropic properties are especially essential in paints and coatings.
What is the purpose of the thixotropic?
Thixotropic gel forms a barrier between blood cells and serum or plasma, thus preventing contamination and allowing easy separation.
What is thixotropic material?
| What are Thixotropic Materials? Materials that are thixotropic have a time-dependent, shear-thinning viscosity. In other words, as the material is placed under stress to flow, the longer the stress is applied, the lower the viscosity will be. Thixotropy can be quantified as the “thixotropic index” of a material.
How does a thixotropy work?
‘Thixotropy’ is shear thinning property; when an alloy is sheared it thins, but when it is allowed to stand it thickens again. This behavior is associated with the breakup of agglomerates of solid particles under shear and their reformation when the shear is removed.
What is the role of thixotropy in formulation?
Modification of polymer structure/component. Thixotropic property plays a key role in liquid filling of hard gelatin capsules, and there is a positive relationship between the dispersed phase for the proper filling of molten dispersions into capsules and apparent viscosity of the formulation [59].
What are thixotropic materials?
Thixotropic materials display a viscosity that decreases with shear rate and time of shear as well. They possess a solid structure that requires time to form under high pressure (or low temperature) and that structure is disrupted by shear stress.
What is thixotropic coating?
What is thixotropy and how does it influence the manufacturing of paint and related products? Thixotropy is a property of some products which change their viscosity and become more fluid when subject to constant shear force, e.g., in the mixing stage. The longer the fluid is under shear stress, the less its viscosity.
What is thixotropy in connective tissue?
Connective tissue has the ability to change state, depending on its level of energy and activity. This property, called thixotropy, means that the fascia can move from a gel-like state to a liquid-like state and back.
How does the thixotropy affect the stability of a formulation?
In the case of both suspending agents employed, the correlation of physical suspension stability and the degree of thixotropy of the suspending agent indicated that sedimentation velocity was directly proportional to the reciprocal of thixotropic area.
What is thixotropy in massage therapy?
You may remember the term thixotropy from a course on myofascial work. It is a phenomenon in which gels become more fluid when they are stirred up and more solid when they are left undisturbed.
