PPG-3 Myristyl Ether Neoheptanoate is a polymeric ester with superior pigment-wetting properties. Its unique structure contains a polymer linked to a fatty acid through an ether linkage. The polymeric portion forms bridges in liquid dispersions to stabilize the system while the ester portion of the molecule acts as a solvent to further stabilize the system. These properties allow for extremely stable fluid dispersions at high concentrations whether using PPG-3 Myristyl Ether Neoheptanoate by itself or as part of a dispersion.
PPG-3 Myristyl Ether Neoheptanoate exhibits superior wetting and dispersing properties for metallic oxides of Titanium, Zinc, and Iron. This allows for better pigment coverage, particularly with high pigment loads and lower viscosities with high pigment concentrations.
A suspension viscosity evaluation is an easy, quantitative method to determine the effect that a dispersion vehicle will have on pigment wetting. The lower the viscosity of the resulting suspension, the better the wetting. Differences in viscosity will have profound effects on product attributes, manufacturing processes, and overall product performance.
