Renfert Prebonder surface pro - 50 µm

Renfert Prebonder surface pro is a 50 µm aluminum-oxide abrasive developed specifically for standardized surface conditioning before adhesive cementation. Its defined particle geometry, hardness and purity are matched to the Renfert Basic prebonder process for treating zirconia, metal alloys, hybrid materials and modern polymers.

Features and Benefits

• Purpose-built prebonding abrasive: Designed for controlled conditioning of restoration surfaces before cementation.
• Defined 50 µm grit: Supports repeatable surface treatment with the Basic prebonder system.
• High-purity aluminum oxide: Renfert specifies greater than 99.7% Al₂O₃ purity.
• Broad material compatibility: Intended for zirconia, metal alloys, hybrid materials and polymers.
