N,N-Diethylaminoethyl Methacrylate is a monofunctional methacrylate and tertiary amine that can be used in with Type II photoinitiators to generate free radicals.   It is  water-soluble, monofunctional and can improve adhesion of formulations.

Dimethylamino ethyl methacrylate, also known as MADAME or DMAEMA, serves as a reducing agent or electron donor when paired with type II photoinitiators. It is water-soluble, monofunctional and can improve adhesion of formulations.

DHEPT or N-N-bis(2-hydroxyethyl)-P-toluidine  is a solid amine that is ideal for chemical-cure systems using peroxides. Good for color sensitive applications, DHEPT serves as an alternative to DMAEMA or DMPT.

Ethyl-4-dimethylamino benzoate is a tertiary amine synergist typically used in combination with type II photoinitiators such as Benzophenone. It is best known for it’s ability to promote surface cure. It is soluble in most monomers, oligomers and pre-polymers but insoluble in H₂O.
