FAQs
What is N,N-dimethylbenzylamine used for?
N,N-Dimethylbenzylamine (BDMA or DMBA) is a tertiary amine used mainly as a catalyst and accelerator. It is well known as an accelerator for curing epoxy resins and as a catalyst in polyurethane foam systems, and it also serves as a reagent in various organic synthesis applications.
What are the purity and identity?
This TCI product (D0688) is a minimum 98.0% (GC) grade, CAS number 103-83-3, with molecular formula C9H13N and molecular weight 135.21. It is a colorless to almost colorless clear liquid. Synonyms include N-benzyldimethylamine, BDMA, and DMBA. Confirm these identifiers when ordering.
Is BDMA hazardous?
Yes. It is a flammable, corrosive amine that is toxic if swallowed and can cause severe skin burns and eye damage. Handle it with appropriate protective equipment and adequate ventilation, keep it away from ignition sources, and always review the Safety Data Sheet. The product also carries a California Prop 65 warning.
How does BDMA accelerate epoxy cure?
As a tertiary amine, BDMA acts catalytically in epoxy systems, promoting the curing reaction and shortening cure time. It is widely used where faster or lower-temperature cure is desired. Formulators add it in controlled amounts; consult your resin system's guidance for appropriate loading and handling in your process.
What sizes are available?
The reagent is offered in 25 mL and 500 mL sizes. Choosing a size close to your usage helps manage a flammable, corrosive material, since buying only what you will use within a reasonable period limits storage of hazardous chemicals and reduces waste while maintaining quality.
