1788, 2088, 0588, 0388
Partially hydrolysed grades disperse at room temperature.
1799, 2099, 2499, 2699
Fully hydrolysed film is denser and more resistant.
1799
Strong film, good wet-out on polyester, low end-break rate.
1788
Cold soluble and blends 1:1 with modified starch.
1788
20.5–24.5 mPa·s is the industry default window.
0388
3.0–4.0 mPa·s, the lowest in the range.
2688
DP 2600 gives body at 8–12% solids.
2088, 1588
Dry film re-activates with a little cold water.
2699 (cost option 2488)
0.5–2% extends open time and resists cracking.
0599, 0499
Low DP allows high solids at workable viscosity.
1599
High hydrolysis controls particle size and wall build-up.
1099, 1299, 1588
Moderate viscosity bonds fibre and filler.
2488, 2688
High DP holds water and resists sag.
