OMG Borchers Borchi Gel 0625 Thickener – Frequently Asked Questions (FAQ)
Q1: What type of thickening mechanism does Borchi Gel 0625 provide?
A: Borchi Gel 0625 is a hydrophobically modified ethoxylated urethane (HEUR) rheology modifier that functions via associative thickening—forming transient networks between hydrophobic end groups and surfactants or polymer particles in the formulation.
Q2: In which types of waterborne systems is Borchi Gel 0625 most effective?
A: It delivers optimal performance in low-to-medium VOC architectural coatings, industrial maintenance paints, and water-based wood finishes—particularly where high-shear viscosity control, spatter resistance, and sag resistance are required.
Q3: How should Borchi Gel 0625 be incorporated into a formulation?
A: It is typically added during the let-down stage, after pigments and primary thickeners, under moderate agitation. Pre-dilution with water or co-solvent is recommended to ensure uniform dispersion and avoid localized overdosing.
Q4: Does Borchi Gel 0625 require pH adjustment for activation?
A: No—unlike alkaline-swellable thickeners (ASE), Borchi Gel 0625 is pH-independent and performs consistently across typical coating pH ranges (pH 6–10) without requiring neutralization.
Q5: Can Borchi Gel 0625 be used alongside other rheology modifiers?
A: Yes—it is commonly combined with cellulosic or inorganic thickeners to balance low-shear and high-shear rheology; however, compatibility testing is advised to avoid antagonistic interactions, especially with high levels of anionic surfactants.
