Dispersing Agents & Surfactants

Dispersing Agents

What are dispersing agents? Dispersing agents are surfactants that keep solid particles—pigments, fillers, dyes—uniformly distributed in a liquid and prevent settling or flocculation. They adsorb on particle surfaces and provide electrostatic or steric stabilization. Esteem supplies anionic naphthalene-based and related dispersants for paint & coating, paper, and textile applications where stable dispersions are critical.

Key benefits of our dispersing agents

• Stable, fine dispersions of pigments and fillers that improve color strength, gloss, and hiding power in final formulations.
• Reduced settling, flocculation, and viscosity drift over storage, supporting longer shelf life and easier handling.
• Improved grinding and dispersion efficiency, allowing lower energy input or shorter dispersion times during manufacture.

Typical applications

• Pigment dispersions for architectural and industrial coatings where uniform color and film appearance are essential.
• Paper and board systems requiring stable filler and pigment distribution for consistent optical and strength properties.
• Textile dyeing and printing processes in which dispersants help manage disperse dyes and particulate additives in the bath.

Technical highlights

• Anionic naphthalene-based dispersants and related chemistries engineered for strong adsorption on particle surfaces and electrostatic stabilization.
• Compatibility with common binder systems, resins, and auxiliary packages used in coatings, paper, and textile plants.
• Supported by technical guidance on dosage, order of addition, and process conditions to optimize performance in your specific systems.
