Overview
2,4,6-Tris(dimethylaminomethyl)phenol , also known as CAS 90-72-2 , is a tertiary amine curing agent and accelerator for epoxy resin systems. It accelerates epoxy cure at ambient or elevated temperatures, reducing processing time across a broad range of industrial formulations.
In structural adhesives and composite manufacturing, this chemical initiates and accelerates epoxy crosslinking, enabling room-temperature cure without external heat input. This efficiency is vital for large-scale production cycles.
Coatings formulators use it to harden epoxy floor coatings, protective linings, and corrosion-resistant topcoats where controlled pot life and full cure development are critical. It ensures the durability of industrial surfaces.
In electrical encapsulation and potting compounds, it ensures complete cure of epoxy systems around sensitive components. This supports dimensional stability under thermal cycling and protects delicate electronic hardware.
Polyurethane and phenolic resin producers also incorporate it as a catalyst to drive crosslink density in elastomers and sealants. This versatility makes it a staple in modern polymer chemistry and material science.
The product is supplied as an amber to yellow liquid. Standard commercial grades are available at high purity, typically greater than or equal to ninety-eight percent, for industrial and specialty applications.
Technical-grade material is the predominant market form, with packaging ranging from small laboratory quantities to drum-scale supply for production environments. It meets rigorous industrial requirements for consistency.
