Croda Hypermer KD Dispersant – Frequently Asked Questions (FAQ)

Q1: What types of pigments and fillers is Hypermer KD Dispersant most effective with?

A: Hypermer KD Dispersant is especially effective with inorganic pigments such as titanium dioxide, iron oxides, and carbon black, as well as functional fillers like calcium carbonate and silica. Its molecular architecture provides strong anchoring and steric stabilization in both aqueous and solvent-based systems.

Q2: Can Hypermer KD Dispersant be used in waterborne coatings without compromising stability or film formation?

A: Yes — Hypermer KD Dispersant is formulated to deliver excellent colloidal stability in waterborne acrylic, polyurethane, and hybrid systems. It helps reduce viscosity, improve pigment grind efficiency, and supports long-term storage stability without interfering with coalescence or film integrity.

Q3: How does Hypermer KD Dispersant compare to traditional polymeric dispersants in terms of dosage and efficiency?

A: Hypermer KD Dispersant typically delivers high efficiency at lower dosage levels compared to many conventional polymeric dispersants, due to its optimized balance of anchor groups and solvating chains. Dosage generally ranges from 0.1% to 2% by weight relative to pigment, depending on pigment surface area and formulation complexity.

Q4: Is Hypermer KD Dispersant compatible with common rheology modifiers and biocides used in industrial coatings?

A: Yes — Hypermer KD Dispersant demonstrates broad compatibility with associative and non-associative thickeners (e.g., HEUR, HEC), as well as standard isothiazolinone and benzisothiazole biocides. Compatibility should always be confirmed under actual formulation conditions and shear history.
