What is Dimorpholinomethane?
Dimorpholinomethane (CAS 5625-90-1), also known as 4,4-Methylenedimorpholine, is a morpholine-derived amine used industrially as a biocide and corrosion inhibitor.
Where is Dimorpholinomethane used?
- Metalworking fluids: formaldehyde-releaser biocide controlling bacterial and fungal growth
- Water-miscible cutting and grinding fluids: extends fluid service life
- Water treatment: suppresses microbial fouling in recirculating cooling systems and process water
- Coatings, adhesives and sealants: preservation agent preventing microbial degradation during storage
- Textile processing and leather finishing: antimicrobial protection
- It releases formaldehyde slowly, providing controlled antimicrobial and metal-protection activity in aqueous systems.
Commercial specifications
- Liquid, around 80% active content in aqueous solution
- Packaging from drums to intermediate bulk containers
