Q1: What is the primary thickening mechanism of Borchi Gel L75N?
A: Borchi Gel L75N functions as an associative thickener, relying on hydrophobic interactions between its alkyl chains and other formulation components (e.g., surfactants or polymer backbones) to form a transient, three-dimensional network that imparts viscosity and rheological control.
Q2: How does Borchi Gel L75N differ from conventional cellulosic or acrylic thickeners?
A: Unlike non-associative thickeners, Borchi Gel L75N delivers superior shear-thinning behavior, enhanced gloss retention, and improved compatibility with surfactants and co-solvents—making it especially suitable for high-performance architectural coatings, industrial finishes, and cleaning formulations where flow/leveling and stability are critical.
Q3: Is Borchi Gel L75N compatible with anionic, nonionic, and cationic systems?
A: Borchi Gel L75N exhibits broad compatibility across anionic and nonionic surfactant systems and is widely used in such environments. Compatibility with strongly cationic systems should be evaluated case-by-case, as charge interactions may affect thickening efficiency or colloidal stability.
Q4: What is the recommended addition method for optimal performance?
A: For best results, Borchi Gel L75N should be added during the let-down stage under moderate agitation—preferably after dispersants and pigments have been stabilized—to ensure uniform distribution and avoid localized overdosing or viscosity spikes.
Q5: Does Borchi Gel L75N require pH adjustment or neutralization to activate?
A: No, Borchi Gel L75N is a non-ionic associative thickener and does not rely on pH-dependent ionization for thickening activity—unlike some polyacrylic acid-based thickeners—making it effective across a wide pH range without neutralization steps.
