Seb Posted May 5, 2018 Report Share Posted May 5, 2018 Hello everyone, I am wondering if anybody can give me an advice on deflocculation? I am trying to adjust the viscosity of one gallon slip "Cone 06 Casting Slip - White" from a ca 50 seconds runtime, to ca 30 seconds. I have used dispersal "Darvan 7" in small increments and I am not adding water! For some reason, the slip does not seem to change significantly. Could there be an issue that I am not aware of? About how much would I roughly need to add to a gallon to get the running time down about 20 seconds under normal circumstances? Any advice would be so much appreciated! Thanks everyone, Seb Link to comment Share on other sites More sharing options...
Min Posted May 5, 2018 Report Share Posted May 5, 2018 Any chance the darvan has expired? (approx two year shelf life) Link to comment Share on other sites More sharing options...
