Ethanolamine-based Color Paste

Updated: 2026-07-15

Overview

Ethanolamine-based color paste is a stabilized pigment dispersion where ethanolamine derivatives act as wetting and dispersing agents. These formulations are particularly valued in industries requiring precise color matching and long-term stability. The ethanolamine component enhances compatibility with aqueous systems while preventing pigment settling. Unlike solvent-based alternatives, ethanolamine color pastes offer lower VOC emissions and easier cleanup. They are commonly standardized by pigment content (typically 20-50%), viscosity, and pH range (usually 8-10). Manufacturers often provide custom formulations to meet specific application requirements.

Physical and Chemical Properties

The physical properties vary significantly depending on the pigment type, but all ethanolamine color pastes share common characteristics from their amine-based stabilization system. Viscosity typically ranges from 500-5,000 cP at 25°C, with shear-thinning behavior advantageous for pumping and mixing operations. Chemically, the ethanolamine groups provide alkaline stabilization (pH 8-10), which prevents microbial growth and maintains dispersion stability. These pastes demonstrate excellent freeze-thaw resistance (-5°C to 40°C) and shelf lives of 12-24 months when stored properly. Compatibility testing is recommended when mixing with acidic components.

Main Applications

In textile printing, ethanolamine color pastes dominate for their penetration consistency and wash-fastness. They account for approximately 60% of pigment printing pastes in industrial textile production. The paper industry utilizes them for coated papers requiring high opacity and brightness. Industrial coatings represent another major application, especially for waterborne architectural paints where the amine stabilization prevents flash rusting on metal substrates. Emerging uses include 3D printing inks and leather finishing, where pH stability during curing is critical.

Safety and Storage

While generally low-hazard, ethanolamine color pastes require basic precautions. Use nitrile gloves and eye protection when handling, as the alkaline nature may cause mild irritation. Spills should be contained with absorbent materials and cleaned with copious water. Storage tanks should be made of stainless steel 304 or polyethylene. Maintain temperature above 5°C to prevent crystallization and below 30°C to avoid viscosity changes. Drum storage should follow a FIFO system, with containers kept tightly sealed to prevent carbon dioxide absorption that could alter pH.

B2B Procurement Guide

Industrial buyers should specify five key parameters: pigment concentration (%), viscosity range, pH tolerance, particle size distribution (typically <10μm), and compatibility requirements with target resins/systems. Technical datasheets should include rub resistance and lightfastness ratings (ISO 105 standards for textiles). Bulk purchasing (1+ metric tons) typically reduces costs by 15-20%. Consider regional suppliers for logistics efficiency, as freight costs can equal 10-15% of product value. Quality certifications to request include ISO 9001, ECO PASSPORT by OEKO-TEX®, and REACH compliance documentation.
