Renfert Prebonder Surface Pro - 50μm

Renfert Prebonder Surface Pro - 50 microns Abrasive for surface conditioning prior to final cementation. What is it used for? The highly specialized Renfert Prebonder Surface Pro abrasive material was developed specifically for use for the final cementation of restorations. What makes Prebonder Surface Pro special? Clinical surface conditioning through focused sandblasting ensures a reliable final bond on zirconium oxide, metal alloys, hybrid materials, and modern polymers. The 50 μm aluminum oxide (Al₂O₃), with defined grain size distribution, particle shape, hardness, and purity, creates — together with the Basic Prebonder sandblasting unit and coordinated parameters — the ideal micromechanical retention for durable bonding. Advantages Scientifically validated: Optimized through extensive in-vitro studies for maximum bond strength in final cementation. Reproducible results: Precisely defined grain geometry, material hardness, and purity for consistently high surface quality. Gentle on materials: Focused surface transformation for ideal micromechanical retention without aggressive processing or loss of flexural strength. Details Practice-oriented packaging: Airtight 500g units protect against humidity and are tailored to usage frequency in dental offices. Specifically for: Surface conditioning of fixed dental restorations prior to final cementation. Suitable for: Zirconium oxide, metal alloys, hybrid materials, modern polymers. Exclusively for: Basic prebonder special tank. Optimal working pressure: 0.6–1.0 bar (recommended: 0.8 bar). Grain size: 50 μm Al₂O₃. Purity: > 99.7% aluminum oxide. Scope of delivery: 4 × 500 g airtight sealed units.
