Which factor can slow down the setting time of zinc phosphate cement?

Show Answers

Raising the powder-to-liquid ratioAdding water to dilute the liquid componentIncreasing the amount of powder relative to liquidReducing the quantity of powder mixed with the liquidUsing a warmer mixing environment

Explanation

The setting time of zinc phosphate cement is prolonged when the amount of powder is decreased relative to the liquid. This reduction in powder slows the chemical reaction, delaying the setting process.
