Recommended levels/use

Ladder studies are recommended to determine optimum level. Normal dosage ranges from 0.05 to 0.5 % on finished product. AGITAN E 255 is typically added undiluted during pigment grinding for optimum distribution and de-aeration. For most efficient use 2/3 of AGITAN E 255 is added to the pigment dispersion and 1/3 is added to the letdown.
