This document specifies two methods for the determination of the surface tension of polymer dispersions and rubber latices (natural and synthetic).
-
Method A is the ring method (Du Noüy ring method).
-
Method B is the plate method (Wilhelmy plate method).
MethodA is suitable valid for polymer dispersions and rubber latices with a viscosity less than 200mPa·s.
MethodB is not suitable for polymer dispersions and rubber latices containing cationic surfactants.
MethodsA and B are also suitable for prevulcanized latices and compounded material.
In case of dispute, the preferred method is method A (the ring method).
