What is N,N,4-Trimethylpiperazine-1-ethylamine?
N,N,4-Trimethylpiperazine-1-ethylamine (CAS 104-19-8), also known commercially as Addocat PP, is a tertiary amine used as a catalyst in polyurethane and polymer systems.
Where is N,N,4-Trimethylpiperazine-1-ethylamine used?
- Polyurethane foam and elastomer production: blowing and gelation catalyst, balancing competing reactions that determine cell structure and mechanical performance
- Coatings: cure-speed tuning in two-component polyurethane systems where pot life and through-cure must match application conditions
- Adhesives and sealants: supports crosslink density development, affecting bond strength and flexibility
- Rigid and flexible polymer systems: controlled amine catalysis during processing
- It accelerates curing and crosslinking reactions, allowing formulators to control reaction speed and network development.
Commercial specifications
- Drum and IBC quantities for industrial-scale polyurethane and polymer processing
