Enamels and paints are generally _______________ fluid?
Correct answer: A. Pseudo-plastic
- A. Pseudo-plastic
- B. Rheopectic
- C. Thixotropic
- D. Dilatant
Explanation
Paints and enamels commonly show pseudoplastic behaviour, meaning their apparent viscosity decreases as shear rate increases, making them easier to spread. Thixotropy may also occur, but it specifically involves time-dependent viscosity reduction under shear.
