Starting formulation:
for a 30 % solution:
615.9 g Water
0.1 g Drewplus TS – 4387
300.0 g Indurez SR 10
84.0 g Ammonia solution 25 %
------------- 1000.0 g
Viscosity: appr. 300 mPa.s (Anton Paar RheolabQC; MS: CC27)
Add the Indurez SR 10 to water at room temperature.
Stir to ensure complete wetting of the solid resin.
Add the ammonia solution.
While stirring heat up to minimum 80°C.
Stir until the solid resin has completely dissolved. pH value should be at least 8.2.
