What is tris(N-hydroxyethyl) hexahydrotriazine?
Tris(N-hydroxyethyl) hexahydrotriazine (CAS 4719-04-4) is a triazine-based biocide and corrosion inhibitor for industrial preservation and fluid protection.
Where is tris(N-hydroxyethyl) hexahydrotriazine used?
- Metalworking and cutting fluids: suppresses bacterial and fungal contamination that shortens fluid service life
- Water treatment: controls sulfate-reducing bacteria and biofilm in cooling towers and industrial water circuits
- Oil and gas: dosed into injection and produced water systems to inhibit microbial-induced corrosion in pipelines and downhole equipment
- Coatings and adhesives: in-can preservative that protects products against microbial spoilage during storage and distribution
- It controls microbial growth and prevents metal degradation in water-containing systems.
Commercial specifications
- Aqueous solution, typically around 78–80% active content
- Packaging from drums to IBC containers
