For professionals in the chemical and environmental treatment industries, understanding the chemical identity and application of key compounds is fundamental. CAS number 55295-98-2 refers to a specific type of polymer: Dicyandiamide Formaldehyde Resin. This compound is the active ingredient in many high-performance Water Decoloring Agents, offering potent solutions for industrial wastewater challenges. This article aims to provide B2B buyers, R&D scientists, and product formulators with a comprehensive overview of this important chemical.

What is CAS 55295-98-2?
Chemically, CAS 55295-98-2 is a cationic polymer formed through the reaction of dicyandiamide, formaldehyde, and often ammonium chloride. This polymerization process creates a robust molecular structure that imparts excellent water-soluble properties and a high density of cationic charges. These characteristics are precisely what make it so effective as a decolorizing flocculant.

Key Properties and How They Benefit Applications:

  • Cationic Nature: The positive charges on the polymer backbone are highly effective at neutralizing the negative charges present on dye molecules and other colloidal particles found in industrial wastewater. This charge neutralization is the primary mechanism for destabilizing and aggregating pollutants.
  • High Molecular Weight & Cross-linking: These properties contribute to the formation of large, dense flocs that settle rapidly, leading to efficient separation of solids from the liquid phase.
  • Water Solubility: The polymer is readily soluble in water, making it easy to dose and handle in typical wastewater treatment systems.
  • Stability: Dicyandiamide Formaldehyde Resin exhibits good hydrolysis and thermal stability, ensuring consistent performance across a range of conditions. It also shows good stability against chlorine, which is a common concern in water treatment.
  • Environmental Profile: When properly applied, these resins are considered environmentally friendly, contributing to significant reductions in color, COD, and BOD without introducing harmful heavy metals or excessive sludge.

Primary Applications: Water Decoloring Agents
The most prominent application for CAS 55295-98-2 is as the key component in Water Decoloring Agents. These agents are indispensable for:

  • Textile, Dyeing, and Printing Industries: Treating wastewater laden with reactive, acid, disperse, and direct dyes.
  • Paper and Pulp Mills: Used both for effluent decolorization and as a retention agent during paper production.
  • Ink and Pigment Manufacturing: Managing colored wastewater streams.
  • Other Industrial Effluents: Applicable to various industries requiring color and COD reduction.

Procurement and Technical Considerations
When sourcing products containing CAS 55295-98-2, B2B buyers should look for suppliers who provide detailed technical data sheets, information on solid content (typically 50-60% for liquid formulations), viscosity, and pH. Understanding the typical dosage ranges and compatibility with other treatment chemicals (like PAC) is also vital for optimizing treatment processes. Partnering with a reputable manufacturer ensures consistent product quality, reliable supply, and expert technical support to help you leverage the full potential of this powerful chemical.
