Description
Igepal® CO-520 is a nonyl phenol ethoxylate (5 moles EO) and an emulsifier and coupling agent.
The Solvay Igepal® range of alkylphenol ethoxylates is designed to improve the stability performance of a wide range of polymer systems at the usage level of 0.5-3.0% (based on total monomers). The low ethoxylated Igepal products are also suitable for being used as wetting agents. The Igepal products are only suitable for solvent-borne system if their HLB value below 10.0.
The binders emulsified with these Igepal nonionics can be formulated into a broad range of applications, paints, and coatings, adhesives, paper, textile, etc. They can be added during the polymerization as well as the post additives for improvement of mechanical, freeze-thaw, and chemical stability. When added during the polymerization, the stability of pre-monomer emulsion can be improved as well.
Applications for Igepal® CO-520
Igepal® nonionics are very effective and efficient. In most applications, these nonionics deliver significant performance improvement at a low usage level, such as:
- Stability: mechanical, chemical, freeze-thaw, and pre-monomer emulsion
- Wetting: pigment, substrates, etc
- Color acceptance
- Less water-sensitive versus the anionic
- Less foaming tendency versus the anionic
