Addition and Dosage

The optimal amount of PAT-ADD AF 70 to be used is system related, but generally is between 0,1 and 0,8 % PAT-ADD AF 70, calculated on the total weight of formulation. Appropiate incorporation conditions have to be provided, which are related to system characteristics, such as viscosity and solvent composition. However, typically standard let-down conditions (mixer) may be applied. The optimum concentration to be used depends on the individual requirements and conditions.
