Q1: What is the primary functional role of NATROSOL HE 3KB in water-based formulations?
A: NATROSOL HE 3KB functions primarily as a non-ionic rheology modifier and thickener. It provides excellent viscosity development, shear-thinning behavior, and suspension stability in aqueous systems, making it especially valuable in paints, coatings, adhesives, and construction mortars.
Q2: How does NATROSOL HE 3KB differ from other NATROSOL HE grades, such as HE 100 or HE 250?
A: NATROSOL HE 3KB is specifically designed for balanced performance in mid-to-high-shear applications, offering enhanced water retention and improved sag resistance compared to lower-viscosity grades. Its molecular weight and substitution profile are optimized for robust thickening efficiency and compatibility with common co-additives like biocides and defoamers.
Q3: Is NATROSOL HE 3KB suitable for use in architectural coatings exposed to freeze-thaw cycles?
A: Yes — when properly incorporated and formulated, NATROSOL HE 3KB contributes to improved freeze-thaw stability in latex-based architectural coatings. Its non-ionic nature minimizes sensitivity to electrolytes and pH shifts, supporting consistent viscosity recovery after cycling.
Q4: What is the typical dosage range for achieving target viscosity in waterborne paint systems?
A: Dosage is formulation-dependent, but NATROSOL HE 3KB is typically used at low concentrations — generally ranging from 0.1% to 2% by weight of the total formulation — to achieve desired rheological profiles without compromising film formation or clarity.
