Q1: What is the primary function of POLARGEL in formulations?
A: POLARGEL is a sodium bentonite-based rheological modifier designed to provide suspension stability, yield stress development, and thixotropic behavior in aqueous systems—particularly where controlled flow and anti-settling performance are critical.
Q2: How does POLARGEL differ from conventional bentonite thickeners?
A: POLARGEL is pre-activated and surface-modified to deliver rapid, consistent dispersion and enhanced swelling efficiency in water without requiring extended aging or high-shear pre-hydration—reducing processing time and improving batch-to-batch reproducibility.
Q3: Is POLARGEL compatible with electrolytes and moderately acidic or alkaline systems?
A: POLARGEL demonstrates improved tolerance to moderate ionic strength and maintains functional viscosity across a pH range of approximately 5–10, though performance may diminish under highly saline or strongly acidic conditions (pH < 4) due to clay platelet aggregation.
Q4: What types of industrial applications is POLARGEL commonly used in?
A: It is widely employed in water-based coatings, architectural paints, agricultural adjuvants, drilling fluids, and specialty cleaning gels—where reliable suspension of pigments, solids, or active ingredients is required alongside non-drip or sag-resistant application properties.
Q5: How should POLARGEL be incorporated into a formulation for optimal performance?
A: For best results, disperse POLARGEL gradually into the aqueous phase under moderate agitation—preferably using a high-shear mixer—to ensure full wetting and prevent agglomeration. Dosage typically ranges from 0.1% to 2% by weight, depending on desired viscosity and formulation complexity.
