Foredom 3'' Sanding Disc Trizact Psa 400 Grit

Description:

3'' Sanding Disc Trizact PSA 400 Grit is a high-performance dental laboratory finishing disc engineered for consistent surface refinement on a wide range of restorative materials. Using micro-replicated Trizact abrasive technology, the disc features structured abrasive pyramids that wear down uniformly, continually exposing fresh cutting surfaces. This ensures highly predictable and consistent finishing throughout its lifespan�an essential advantage over traditional coated abrasives. The 400-grit classification makes this disc ideal for intermediate finishing and smoothing after initial shaping or trimming. It is frequently used on metal frameworks, zirconia, ceramics, acrylic bases, implant bars, composite resins, and prosthetic components. Its ability to deliver a uniform scratch pattern ensures surface consistency, which makes subsequent polishing steps faster and more efficient. The PSA (pressure-sensitive adhesive) backing allows quick, secure attachment to mandrels or disc holders, ensuring stability during use. This enhances operator control, reduces vibration, and supports cleaner, more precise finishing even on curved or complex prosthetic surfaces. The disc�s 3-inch diameter provides broad coverage, enabling efficient smoothing of large areas such as denture flanges, palatal surfaces, occlusal guards, full-arch frameworks, and ceramic restorations. The Trizact 400-grit disc is especially valuable when preparing surfaces for final high-gloss polishing, staining and glazing, or bonding procedures. By producing a uniform, refined surface, it helps reduce defects and improve the final aesthetic and functional outcome of the restoration. Durable, reliable, and engineered for consistent performance, the 3'' Sanding Disc Trizact PSA 400 Grit is an essential tool in any dental laboratory that prioritizes precision finishing and high-quality restorative craftsmanship.
