Q1: What types of pigment systems is Disponer 983 especially effective for?
A: Disponer 983 is particularly effective for wetting and dispersing inorganic pigments such as titanium dioxide, iron oxides, and carbon black, as well as many organic pigments commonly used in architectural, industrial, and protective coatings.
Q2: How does Disponer 983 contribute to improved coating stability?
A: It enhances colloidal stability by reducing interfacial tension and providing steric stabilization, helping to minimize pigment flocculation, settling, and viscosity drift during storage—especially in water-based systems with high pigment loading.
Q3: Is Disponer 983 compatible with common co-dispersants or rheology modifiers?
A: Yes, it shows good compatibility with a broad range of associative and non-associative thickeners, as well as other polymeric dispersants and surfactants typically used in low-VOC and zero-VOC aqueous formulations.
Q4: What is the recommended addition method for optimal performance?
A: For best results, Disponer 983 should be added during the initial pigment wetting stage—preferably before or concurrently with pigment incorporation—and mixed thoroughly under moderate shear to ensure uniform contact with particle surfaces.
Q5: Can Disponer 983 be used in both ambient-cure and baked systems?
A: Yes, it is thermally stable enough for use in ambient-cure architectural paints as well as low-bake industrial coatings, maintaining performance across typical processing and film-formation conditions without significant degradation or volatilization.
