Renfert Prebonder Surface pro 50 μm, 2 kg
Surface conditioning before final cementation
A specialized abrasive for controlled surface conditioning of fixed dental restorations before final cementation. The aluminum oxide particles have defined grain size distribution, shape, hardness and purity. In combination with the Basic prebonder and matched processing parameters, the abrasive creates a uniform micromechanical retentive surface to support reliable bonding.
Indications and compatibility
Designed for focused surface treatment of zirconia, metal alloys, hybrid materials and modern polymers. For exclusive use in the dedicated tank of the Renfert Basic prebonder; not intended for standard blasting tanks.
Benefits
Defined particle geometry supports reproducible surface quality and gentle, targeted treatment. According to the manufacturer, the abrasive and recommended parameters were optimized through laboratory studies for strong bonding in final cementation.
Technical specifications
Grain size: 50 µm. Material: aluminum oxide (Al₂O₃). Purity: greater than 99.7%. Recommended working pressure with Basic prebonder: 0.6–1.0 bar, with 0.8 bar as the recommended setting.
Package contents
Total 2 kg, supplied in four individually airtight-sealed 500 g bags to help protect the abrasive from moisture.
