MICROSPERSION EZ is a specialized surfactant designed to easily disperse micronized wax polymers such as polyethylene, polypropylene, synthetic wax and PTFE into water.
Surface tension or surface energy is a function of the force of attraction between molecules. The force of attraction in nonpolar hydrocarbon wax molecules is much weaker than the attractive force between water molecules.
All of the Micro Powders micronized wax polymers have low inter-molecular forces and thereby have low surface energy. Wax polymer molecules, by nature, do not interact well with water molecules. Waxes usually exhibit low surface energy and are considered hydrophobic, thus for a liquid such as water to wet out a wax, it requires the liquid to have a lower surface tension than that of the wax. high solids dispersions with these type of waxes may need a higher dosage.
