Q1: What types of pigments and fillers is TEGO Dispersogen 740W especially effective for?
A: TEGO Dispersogen 740W demonstrates strong performance with inorganic pigments such as titanium dioxide and iron oxides, as well as with common functional fillers like silica, calcium carbonate, and talc—particularly in aqueous systems where steric stabilization is required.
Q2: Can TEGO Dispersogen 740W be used in combination with ionic dispersants or rheology modifiers?
A: Yes, its non-ionic nature provides good compatibility with many anionic and cationic additives, including polyacrylate dispersants and associative thickeners—though compatibility should always be verified in the final formulation due to potential interactions.
Q3: How does TEGO Dispersogen 740W contribute to long-term storage stability of pigment dispersions?
A: It provides robust steric stabilization that helps prevent pigment agglomeration and settling during storage, supporting improved viscosity stability and reduced flocculation over time—especially under moderate temperature variations and extended shelf life conditions.
Q4: Is TEGO Dispersogen 740W suitable for low-VOC or high-solids waterborne coatings?
A: Yes—it is designed for use in environmentally compliant aqueous systems, including low-VOC and high-solids formulations, where efficient wetting and dispersion are needed without introducing significant volatile content or compromising film formation.
