Jun 21, 2017  Long mixing times can cause gum degradation and result in poor quality dispersion. Filtering agglomerates out of the mix further adds processing time and is a waste of costly raw materials. As a result, many formulations contain unnecessarily high levels of gums to compensate for the poor yield, which again increases raw material costs.
