11. It is a dark green, gelatinous, thixotropic substance used to clean garages and machine shops. 12. Fumed silica is commonly used as a rheology agent to make otherwise low-viscous fluids thixotropic . 13. Thixotropic behaviour is the result of a break down in the microstructure of the material as shearing continues.14. Using a micromanipulator and microdissection, Seifriz showed that protoplasm was non-Newtonian, thixotropic and elastic. 15. Many kinds of paints and inks e . g . plastisols used in silkscreen textile printing exhibit thixotropic qualities. 16. It is very thixotropic above 1 % concentration, but below 0.3 %, the thixotropy is slight. 17. Some fluids are anti-thixotropic : constant shear stress for a time causes an increase in viscosity or even solidification. 18. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler. 19. As ketchup has high viscosity and behaves as a pseudoplastic or thixotropic liquid, dispensing from glass bottles can be difficult. 20. Cast from highly viscous, thixotropic material, dams can be filled with resin of low viscosity ( dam & fill ).
