Grade specific

Ultra-Low Viscosity Fine Emulsion

3.0–4.0 mPa·s band

The lowest viscosity in the range, which is what allows fine-particle, high-solids PVAc emulsion to stay pourable.

Dissolves almost instantly

Fast wet-out supports continuous feeding instead of batch make-down.

Rarely used alone

Film strength is low. Blend with 088-20 or a mid-DP grade to recover cohesion while keeping the viscosity low.

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.
