Stackable consistency helps prevent material slumping A3 shade supports a natural tooth-colored core Dual-cure chemistry supports varied curing access Radiopacity supports clear x-ray identification Fluoride-releasing resin adds restorative value Quantity: 2 per Pack Premier Dental CompCore AF SyringeMix STACK Core Build-Up Material, Dual-Cure, Intro Kit, 9 Gram, A3 is used for rebuilding missing coronal tooth structure before indirect restorative procedures when a stackable dual-cure core composite is preferred. The A3 shade gives this version a natural tooth-colored appearance that can blend more discreetly beneath ceramic restorations while still maintaining radiographic visibility, and CompCore AF STACK is formulated to stay where placed during buildup, including maxillary preparations, yet flow under pressure for close adaptation. Each introductory kit contains two 9g dual-barrel automix syringes in Shade A3, 15 mixing tips, 15 standard intraoral tips, and 10 extra-fine intraoral tips.Dental offices ordering core build-up material from their supplier can buy this A3 shade to distinguish it from the White and Blue SyringeMix STACK variants, since the automix format automatically combines the two components during dispensing, reducing hand-mixing steps and helping maintain consistent material delivery for crown, bridge, and post-endodontic core workflows. CompCore AF uses Hyperbranched Technology and nano-fillers to support mechanical performance, controlled handling, and efficient polymerization. The STACK consistency is designed to resist slumping while still flowing under pressure, helping the material adapt around preparation walls and internal contours. The material can be light cured or allowed to self cure, which supports restorative procedures where light access varies across the core, and Premier Dental lists a 4.5-minute intraoral self-cure time, while White and A3 shades can be light cured to depths up to 8mm in 30 seconds.Radiopacity supports clear identification on radiographs, and the fluoride-releasing formulation adds another useful characteristic for core build-up selection across crown, bridge, and post-endodontic procedures.
