Recommended levels/use

Ladder studies are recommended to determine optimum use level. Normal dosage ranges from 0.05 to 0.5 % on finished product. AGITAN 381 is typically added undiluted during pigment grinding for optimum distribution and foam control. For intensive dispersing and grinding, AGITAN 381 should be added in the last third of the processing step. Pre-emulsification into water for post-addition is also possible

Storage & Handling

Storage and Packaging

AGITAN 381 is not sensitive to freezing, but for better handling it should be stored between 5 and 25 °C. The product may slightly separate on storage. Therefore AGITAN 381 must be mixed before use. The minimum shelf life in closed containers is 15 months from the date of manufacture.
