Q1: What type of rheology does Borchi Gel 0625 provide in aqueous systems?
A: Borchi Gel 0625 is an associative thickener that delivers pronounced shear-thinning behavior and excellent low-shear viscosity build, supporting good sag resistance and leveling in coatings and construction formulations.
Q2: How does Borchi Gel 0625 differ from cellulosic or acrylic thickeners?
A: Unlike non-associative thickeners, Borchi Gel 0625 functions via hydrophobic association in water, offering superior compatibility with surfactants and co-solvents, reduced sensitivity to electrolytes, and improved film formation without compromising clarity in transparent systems.
Q3: Is Borchi Gel 0625 suitable for high-pH or alkaline formulations?
A: Yes — Borchi Gel 0625 exhibits good stability across a broad pH range, including alkaline environments commonly encountered in architectural paints and cementitious mortars, without significant viscosity loss or phase separation.
Q4: Can Borchi Gel 0625 be used in combination with other rheology modifiers?
A: Yes — it is frequently combined with inorganic thickeners (e.g., bentonite) or non-ionic polymers to achieve synergistic rheological profiles, though compatibility testing is recommended to avoid antagonistic interactions or viscosity suppression.
Q5: What are the typical handling and addition recommendations for Borchi Gel 0625?
A: It is generally added during the let-down stage under moderate agitation; pre-dilution in water or compatible solvent may aid dispersion. Final dosage depends on formulation requirements but typically ranges from 0.1% to 2% by weight of the total system.
