Q1: What types of pigments and fillers is Dispersogen PTS most effective for?
A: Dispersogen PTS is specifically engineered for efficient stabilization of inorganic pigments (e.g., titanium dioxide, iron oxides) and functional fillers (e.g., calcium carbonate, silica, talc) in aqueous systems. Its performance is particularly strong with high-surface-area and polar particles commonly used in architectural coatings, industrial finishes, and construction chemicals.
Q2: How does Dispersogen PTS improve pigment dispersion stability compared to conventional polyacrylates?
A: Dispersogen PTS features a tailored comb-like architecture with optimized hydrophobic anchoring segments and hydrophilic stabilizing chains, enabling stronger adsorption and enhanced steric hindrance in water-based formulations. This leads to superior resistance against flocculation, sedimentation, and viscosity drift over time—especially under varying pH or electrolyte conditions.
Q3: Is Dispersogen PTS suitable for low-VOC or zero-VOC formulations?
A: Yes—Dispersogen PTS is a non-ionic, APEO-free dispersant supplied as an aqueous solution with negligible volatile organic content. It supports the development of compliant low-VOC and zero-VOC coatings without compromising dispersion efficiency or film appearance.
Q4: What is the typical dosage range for Dispersogen PTS in coating formulations?
A: Dosage depends on pigment type, loading, and desired performance, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to pigment solids. Optimal levels are best determined through lab-scale dispersion trials and rheological evaluation.
