noun
Technical term in rheology: property of certain gels or fluids that become less viscous when shaken, stirred, or otherwise stressed, and return to a more solid state at rest.
この塗料はシキソトロピー性があるため、塗るときはさらさらしているが、塗った後はたれにくい。
Because this paint has thixotropy, it flows smoothly when applied but resists sagging afterward.
Borrowed from English 'thixotropy', itself coined from Greek roots thixis 'touching' + tropē 'turning'.
