Q1: What is the primary functional benefit of NATROSOL Performax HEC in waterborne systems?
A: NATROSOL Performax HEC delivers robust, shear-thinning rheology with excellent sag resistance and brush drag control, while maintaining high clarity and low foam generation—making it especially suitable for premium architectural coatings, industrial waterborne paints, and maintenance coatings where appearance and application performance are critical.
Q2: How does Performax HEC differ from standard hydroxyethyl cellulose thickeners?
A: Performax HEC is a specially engineered grade offering enhanced associative thickening behavior and improved compatibility with common co-thickeners and surfactants. It provides superior viscosity stability across pH variations and better tolerance to electrolytes compared to conventional HEC grades, resulting in more consistent formulation performance during storage and application.
Q3: Is NATROSOL Performax HEC compatible with biocides and other common additives used in waterborne coatings?
A: Yes—Performax HEC demonstrates broad compatibility with isothiazolinone- and benzisothiazolinone-based biocides, as well as common defoamers, dispersants, and coalescing agents. However, optimal compatibility should be verified experimentally within each specific formulation due to potential interactions with high-surfactant or high-electrolyte systems.
Q4: What is the typical dosage range for NATROSOL Performax HEC in architectural latex paints?
A: Dosage is formulation-dependent, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of the total formulation—to achieve target viscosity and rheological profile without compromising film formation or clarity.
