Find the right dispersant for inks, coatings, plastics and textile systems — grades, specs and formulation guidance.
A dispersing agent — commonly called a dispersant — is a surface-active additive that helps break apart pigment agglomerates, improves wetting and prevents re-agglomeration in liquid systems. Our catalog covers both polymeric and small-molecule dispersants tailored for pigment-bearing formulations used in inks, paints, coatings, masterbatches and textile dyeing.
Representative selection — each dispersant includes performance highlights and recommended applications.
Choosing the correct dispersing agent depends on pigment type, solvent system, desired loading and processing method. Below are quick decision points we use during technical screening.
Inorganic vs. organic pigments require polymeric vs. small-molecule dispersants.
Match dispersant solubility to solvent (aqueous, polar, non-polar).
Ball milling, bead milling or high-speed dissolvers influence shear stability needs.
UV stability, gloss, rheology and regulatory requirements vary by industry.
A few technical tips to get the best results from a dispersant:
A dispersing agent is the functional additive; "dispersant" is the common industry term for the same class of materials. Both terms describe chemicals that improve pigment/DYE breakup and stabilize suspensions — we use them interchangeably in product literature.
Typical usage ranges from 0.5% to 5% (w/w) relative to pigment, depending on pigment type and target rheology. Start with lab trials at 0.5%, 1.5% and 3% to find the optimum for color strength and viscosity.
Most dispersants are system-specific. Some polymeric dispersants are formulated to work across polar solvents; however, ionic dispersants optimized for aqueous systems may not perform in nonpolar solvents. Check the product datasheet for compatibility.
At recommended levels dispersants usually do not negatively affect film properties. Excessive dispersant can reduce gloss or alter adhesion. Always evaluate final coating properties after dispersion and film formation.
Yes — our technical team offers custom dispersant development for challenging pigments, specific regulatory constraints, or tailored processing conditions (e.g., high-temperature extrusion for plastics).
