Details:-
RelyX U200 by 3M ESPE is a self-adhesive resin cement indicated for permanent cementation of indirect restorations. It is the latsest generation of the most clinically proven resin cement, available in a Clicker Dispenser and in an easy-to-use automix syringe. This provides comfortable and easy delivery of the cement and is simple and time saving. This high performance self-adhesive resin cement offers high adhesion, resistance to discolouration, no post-operative sensitivities and long term stability of the prosthesis. RelyX U200 contains an additional monomer and all new rheology modifier which leads to better mechanical properties and excellent overall adhesion.
