GC G-CEM One Adhesive Enhancing Primer. This optional Adhesive Enhancing Primer (AEP) is for use with the G-Cem One self-adhesive resin cement. It provides optimal bond strength in challenging clinical situations, such as low retentive surfaces. The chemical initiator in the AEP accelerates the chemical cure of the cement to ensure optimal bonding. The AEP is easy to apply; no additional light-curing is needed – just apply and air-dry. 4ml bottle. ​
