Variables Influencing Microflocculation in Coalesced Emulsion

By Toronto Society for Coatings Technology

One of the problems associated with coalescing higher glass transition temperature (Tg) emulsions is the potential formation of microflocculation. This can have a major impact in the manufacturing filtration process and subsequent application when applied by spray.

An experimental screening design was run to study the possible effects of three manufacturing variables and three formulation variables. For this study a higher Tg styrenated acrylic was tested. Results showed the formulation variables to have a significant effect on microflocculation while the manufacturing process variables did not.
