Summary:Nov 07,2026

High‑molecular dispersants improve pigment grinding efficiency, colour strength and shelf stability for water‑borne paints and inks. Ruico alternatives vs TEGO, BYK, Clariant & Elementis.

Pigment dispersion quality directly determines finished product performance. Insufficient dispersion brings visible problems: low colour strength, pigment flocculation, sedimentation during storage, higher grinding viscosity and poor gloss.

High‑molecular polymeric dispersants work via steric‑hindrance stabilization for both inorganic and organic pigments. Ruico offers diversified dispersant solutions:

  • High‑molecular polymer dispersant RF‑A2360, alternative to TEGO 760W, optimized for water‑borne colour paste manufacturing.
  • Phenolic‑derivative dispersant RF‑A2374, matching Clariant 2774.
  • Anchoring‑type high‑polymer dispersant RF‑A290, equivalent to TEGO755 / BYK‑100 series.
  • Special chelate‑complex dispersant RF‑AR16 as replacement for Elementis 019.

Application practices:  Add dispersants before pigment feeding at grinding stage for  anchoring effect. Adjust dosage based on pigment type (organic pigments normally need higher dispersant loading than inorganic pigments).  Complete storage stability test (heat‑ageing & freeze‑thaw) during lab evaluation.
