N,N-Dimethyl-p-toluidine
N,N-Dimethyl-p-toluidine is a polymerization catalyst for polyesters, acrylate, and epoxy resins.
N,N-Dimethyl-p-toluidine is also used as a hardener for dental cement and in adhesives.
N,N-Dimethyl-p-toluidine serves as an intermediate for photographic chemicals, industrial glues, artificial fingernail preparations, colorants, and pharmaceuticals.

N,N-Dimethyl-p-toluidine reacts with vinyl ether in the presence of copper(II) chloride, giving tetrahydroquinolines.
Further, N,N-Dimethyl-p-toluidine is used to accelerate the polymerization of ethyl methacrylate.
N,N-Dimethyl-p-toluidine is used as an accelerator in preparing dental materials and bone cement to activate the polymerization reaction or when curing methyl methacrylate monomers.
The concentrations in these preparations are usually between 0.5% and 3% (NTP,2012).
N,N-Dimethyl-p-toluidine has been used in acrylic denture materials for 50 years (HSDB, 2015).
In addition, N,N-dimethyl-ptoluidine is an essential ingredient of industrial glues and artificial fingernail preparations when short setting times are needed and is also used as an intermediate in the manufacture of dyes and pesticides.
Applications: Engineered Stone, Pultrusion, Resin Transfer Molding, Filament winding, Chemical anchors & mine bolts, Hand lay-up & spray-up, pH regulators and water treatment products, leather treatment products, adhesives and sealants, coating products, laboratory chemicals, washing & cleaning products and textile treatment products and dyes, dental adhesives.
