Signum metal® bond

An everlasting bond
Signum metal® bond is a new cold bonding system purpose developed by Heraeus Kulzer for coupling composites and acrylics to metal surfaces. Due to its special material composition, the novel "2 bottle system" achieves up to 300% more bond strength and provides the user with above average security.
Thanks to its special material composition, the new Signum metal bond from Heraeus research offers outstandingly high shear and adhesive strength and long-term stability. Its bond strength, especially under stress, is extraordinary, be it with non-precious or precious alloys. This high strength is achieved with so-called Interface Coupling Technology, the exact interaction of both Signum metal bond components I and II.

What is Interface Coupling Technology? So-called bifunctional adhesive molecules, one of the ingredients of Signum metal bond I, anchor themselves to the surface of the metal. The reactive cross-linking molecules of metal bond II search for compatible reaction partners and form a strong chemical bond with the bifunctional adhesive molecules - according to the lock-and-key principle. In so-called "Interface Coupling", the reactive component is activated by light curing. The bond between veneer and metal or acrylic and cobalt chrome denture base is all but inseparable. The restoration is therefore extremely durable. Opaquer and dentine complete the veneer´s build-up.

Applications for Signum metal bond:

Bonding composite to metal surfaces
Bonding to cobalt chrome denture surfaces
Bonding to root canal posts and Maryland bridges
Bonding composite to repaired veneers

Signum metal bond is easier and faster to use than heat-cured or sandblasting systems. This new bonding agent fits perfectly into the Signum system and is suited superbly for use with Signum composite.

Signum metal bond is available as a set (metal bond I and II), or a refill. Similar to other systems, both components are applied with a brush, where the first component is allowed to air-dry and the second component is polymerised in a light-curing unit. The second component is pre-pigmented, similar to an opaquer. Opaquer and veneering material are then built up in the usual manner.
