What is tert-butyldiethanolamine?
Tert-butyldiethanolamine (CAS 2160-93-2) is a tertiary amine-diol used in industrial formulations for pH regulation, corrosion inhibition, and as a reactive or functional solvent.
Where is tert-butyldiethanolamine used?
- Metalworking fluids and lubricants: corrosion inhibitor
- pH buffer that extends fluid service life and protects ferrous and non-ferrous metal surfaces
- Coatings: neutralizing agent for acid-functional resins, improving dispersion stability in waterborne systems
- Water treatment: alkalinity control and corrosion inhibition in recirculating and process water circuits
- Adhesives, sealants and elastomer systems: reactive component or cure modifier where controlled basicity is required
- Its amine and hydroxyl functionality make it a building block and performance additive in specialty chemical systems.
Commercial specifications
- Technical grade standard; purity typically 98% or higher depending on supplier specification
- Packaging from drums to intermediate bulk containers (IBCs)
