Ethyl 4-dimethylaminobenzoate CAS 10287-53-3
Ethyl 4-dimethylaminobenzoate CAS 10287-53-3 is a highly efficient amine accelerator, generally used with free radical photoinitiators, mainly used in paper, wood, metal and plastic surface varnish coating system UV curing, can also be used for a single or multiple monomer UV radiation polymerization reaction. 4-dimethylaminobenzoate (EDB) is an excellent sensitizer. When combined with thioxanthrone and acetophenone, it can not only promote photoactivation, but also effectively eliminate the interference of oxygen on photoinduced polymerization.
