SPIDENT - K-Bond 8th Generation All-Purpose Adhesive - 5ml Bottle

K-Bond is a universal light-curing dental adhesive designed to provide strong, long-lasting adhesion to a wide range of dental and restorative substrates. Thanks to its advanced formulation incorporating the functional monomer 10-MDP and a ternary photoinitiator system (CQ / amine / iodonium), K-Bond ensures a high degree of polymerization conversion, excellent color stability, and optimal bonding performance in restorative dentistry.

K-Bond is indicated for direct composite restorations (all classes), intraoral repair of composites, ceramics, and PFM restorations, desensitization of root surfaces, cavity sealing prior to amalgam placement, and indirect cementation of composite, ceramic, or metal restorations with a primer.

Its formulation combines Bis-GMA for high mechanical strength, 10-MDP for long-lasting chemical adhesion, HEMA for improved wettability, and ethanol as a solvent to facilitate evaporation. The ready-to-use single-drop system ensures simple, fast, and uniform application without stirring.

K-Bond is thus a reliable, versatile, and high-performance adhesive solution for modern restorative dentistry.

Key Benefits

• Universal adhesive: compatible with total-etch, selective-etch, and self-etch techniques
• Suitable for both direct and indirect applications with a single solution
• Dual-cure compatibility without an activator (moderate pH ~3.5)
• Ready-to-use single-drop system: homogeneous solution requiring no mixing
• Optimized polymerization thanks to the three-component photoinitiator system
• Improved color stability and reduced discoloration over time
• Reduced clinical costs due to the absence of a dual-cure activator

Composition

• Bis-GMA: provides high mechanical strength and reduces polymerization shrinkage
• 10-MDP: promotes chemical adhesion to tooth surfaces through the formation of stable salts
• HEMA: improves wettability and the stability of hydrophilic and hydrophobic components
• Ethanol: solvent facilitating evaporation during air-drying
• Three-component photoinitiator system (CQ / amine / iodonium): increases polymerization rate, degree of conversion, and color stability
• Aliphatic amine: improves material stability and reduces long-term discoloration
