High-Viscosity Binder & Water Retention

What it gives

Use it for retention
Blend before you raise dose
Disperse slowly

What to watch

High DP holds water in mortar and putty, extending open time and resisting slump on vertical substrates.
With cellulose ether or starch, 2488 extends open time at a lower total binder load — cheaper than pushing the PVA number up.
Sprinkle flake into moving water at high shear. Dumping it in produces fisheyes that survive screening and show up as lumps in the finished film.

Processing Guidelines

Make-down. Disperse in room-temperature water first, then raise to 70–80 °C to finish dissolution. Typical solution strength is 5–10%. Always add flake into water, never water onto flake, and filter through 60–80 mesh. Strong alkali will cut viscosity — keep pH below 9 unless the formula calls for it.
Concentration. Work at the strength the application needs — adding water later to a gelled batch does not restore the film.
Filtration. Screen the solution before it reaches the machine; gel particles that pass are defects that cannot be removed downstream.
