Q1: What types of pigments and fillers is Gen1255 especially effective for?
A: Gen1255 is particularly well-suited for wetting and stabilizing inorganic pigments such as titanium dioxide, iron oxides, and carbon black, as well as functional fillers like calcium carbonate, silica, and talc in aqueous systems.
Q2: Can Gen1255 be used in both low- and high-solids formulations?
A: Yes — Gen1255 supports stable dispersion across a broad range of solids content, making it suitable for both conventional and high-solids waterborne coatings, inks, and construction adhesives without significant loss of rheological control or storage stability.
Q3: How does Gen1255 compare to traditional polyacrylate dispersants in terms of viscosity development?
A: Gen1255 typically delivers lower initial viscosity and improved flow behavior during pigment grinding, while still providing robust long-term dispersion stability — offering a favorable balance between processing efficiency and final formulation performance.
Q4: Is Gen1255 compatible with common co-additives like defoamers and thickeners?
A: Gen1255 demonstrates good compatibility with widely used non-ionic surfactants, silicone and mineral oil-based defoamers, and associative and non-associative thickeners in typical waterborne systems — though compatibility testing under actual formulation conditions is recommended.
Q5: What is the typical dosage range for Gen1255 in pigment pastes?
A: Dosage generally ranges from 0.1% to 2% by weight relative to pigment, depending on pigment type, surface area, and desired dispersion quality — with optimal levels determined through lab-scale optimization for each specific system.
