Dosage
Borchi® Coll can be incorporated during pigment dispersion or subsequently into finished systems. We recommend the addition of Borchi® Coll into the mill base. Borchi® Coll achieves the optimal performance after 24h storage time. Addition of 1 – 3 % active substance relative to total paint formulation, depending on system, area of application and desired effect. The optimal dosage should be determined in preliminary trials.
