CGI Opaque is a metal‑bonding porcelain designed to create a stable, highly masking foundation layer for PFM restorations while maintaining natural shade control and bond reliability. It bonds to conventional dental alloys and hides the dark metal substrate so subsequent dentine and incisal porcelains can reproduce true tooth color and depth.
Use CGI Opaque in one or two thin, even applications over properly prepared and oxidized metal copings to completely block out gray shine‑through without excessive thickness, then fire according to the recommended opaque cycle before building your body porcelain. The material is shade‑matched to the CGI PFM porcelain system, helping technicians achieve consistent A–D shade reproduction and seamless integration with CGI dentine and incisal powders for everyday single crowns to multi‑unit bridgework
