Enforced with titanium, lathanide, and silica Prevents breakdown of post-to-dentin interface Offers a homogenous mass for compact core build-up Takes 5 minutes to complete application process Flexi-Flow Cem is a composite cement reinforced by titanium, silica, and lanthanide for a compressive strength comparable to natural dentin. The cohesive bonding of these components prevents the dentin interface from breaking down and improves the retention of all prefabricated posts. The combined high-density large particles and the tiny particles with low-density create a homogenous mass for compact core buildup. Flexi-Flow takes five minutes to mix, place, set, and harden, minimizing hydrostatic pressure for a more effective coating of the post and post hole.Each Automix Kit contains 1 (4.5 g) base and 1 (4.5 g) catalyst.
