Taking the Mystery Out of Mix Design

As with any dry instant adhesive, increasing the amount of water added to a fixed amount of powder leads to two fundamental consequences:1. Extra water always leads to increased fluidity and lower viscosity of the liquid lubricant/adhesive. 2. Adding water to a fixed amount of powder will always dilute the adhesive capability of the paste.
