Product Overview: N,N-Dimethylbenzylamine (BDMA)

BDMA, with the chemical formula C₉H₁₃N, is a colorless to yellowish liquid known for its catalytic properties. It is widely used in the polyurethane industry as a curing accelerator for rigid foams, adhesives, and coatings. BDMA’s ability to improve the pre-fluidity of polyurethane foams ensures uniform bubble formation and strong adhesion between the foam and its substrate. In organic synthesis, it acts as a corrosion inhibitor, acid neutralizer, and electron microscope slice embedding accelerator. Furthermore, BDMA is a critical component in epoxy resin systems, where it enhances the curing process of anhydride, polyamide, and aliphatic amine-based formulations.

Technical Specifications

Key Applications of BDMA

1. Polyurethane Industry

BDMA is a vital catalyst in the production of polyurethane foams, including bulk soft foams, rigid foams, and adhesive coatings. Its role in rigid foam applications is particularly noteworthy, as it ensures optimal pre-fluidity and uniform foam structure. This results in improved mechanical properties and strong bonding between the foam and the substrate, making it ideal for insulation materials in refrigerators and construction panels.

2. Organic Synthesis

In organic chemistry, BDMA serves as a catalyst for the synthesis of quaternary ammonium salts and cationic surfactants, which are used in antimicrobial agents and surface treatments. It also acts as an acid neutralizer and corrosion inhibitor in industrial processes, protecting equipment from degradation.

3. Epoxy Resin Systems

BDMA accelerates the curing of epoxy resins in systems involving anhydrides, polyamides, and aliphatic amines. This makes it a preferred choice for electronic potting materials, encapsulation compounds, and marine coatings, where rapid and efficient curing is essential.
