Thixotropy is the property of certain gels or fluids that are thick (viscous) under normal conditions, but flow (become thin, less viscous) over time when shaken, agitated, or otherwise stressed. They then take a fixed time to return to a thicker, more viscous state.
Some thixotropic fluids return to a gel state almost instantly, such as ketchup, and are called pseudoplastic fluids. Others such as yogurt take much longer and can become thicker. Many gels and colloids are thixotropic materials, exhibiting a stable form at rest but becoming fluid when agitated.
The new Crystal Nails Titanium Gel is Thixotropic. Means that it is thick when you scoop out from the jar. It becomes thinner, much workable when you start to play with it. You can easily build arches, and the shape. When you finished application, and double check the nail, it returns to be thicker.
If you are not satisfected with the nail you sculpted, just touch the gel's surface with your brush, and start to pull all away where you want it to be. That will be easy. Than it will fixed exactly in the shape you worked up.
That's why Crystal Nails Titanium Builder Gel is the favorite in most of the European countries. Maybe they don't know the secret, but they feel the workability. Thixotropic gels are the next generation of builder gels.
