OMG Borchers Gen911 Wetting Dispersant – Frequently Asked Questions (FAQ)

Q1: What types of pigments and fillers is Gen911 especially effective for?

A: Gen911 demonstrates strong wetting and dispersing performance with a broad range of inorganic pigments (e.g., titanium dioxide, iron oxides, carbon black) and functional fillers such as silica, calcium carbonate, and clay—particularly where high surface energy or aggregation tendency poses formulation challenges.

Q2: How does Gen911 compare to conventional polymeric dispersants in terms of stabilization mechanism?

A: Gen911 utilizes a tailored comb-type architecture that combines anchoring groups for robust pigment surface attachment with extended steric stabilizing chains, offering improved long-term dispersion stability and reduced viscosity build-up compared to many traditional low-MW surfactants—without relying solely on electrostatic repulsion.

Q3: Is Gen911 suitable for waterborne systems with high electrolyte content or low pH?

A: Yes—Gen911 is formulated to maintain performance across a wide pH range (approximately 4–10) and shows good tolerance to moderate levels of common electrolytes, making it appropriate for challenging aqueous formulations including architectural coatings, industrial waterborne paints, and certain agrochemical suspensions.

Q4: What are typical dosage guidelines for Gen911 in pigment concentrates?

A: Dosage depends on pigment type, loading, and desired rheology, but Gen911 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to pigment solids—with optimal results often achieved through systematic lab-scale evaluation.

Q5: Can Gen911 be used in combination with other additives such as defoamers or rheology modifiers?

A: Yes—Gen911 exhibits good compatibility with common coating additives, including non-ionic defoamers, associative thickeners, and crosslinkers; however, compatibility should always be verified in the final formulation due to potential interactions with highly ionic or strongly adsorbing additives.
