Foredom Sand Disc Triz. 2 Psa 220

Description:

The 2" Trizact PSA 220 Sanding Disc is a precision-engineered fine-finishing abrasive specifically developed to support accurate and consistent surface refinement in dental laboratory environments. Utilizing advanced 3M Trizact micro-replicated abrasive structures, this disc provides predictable and uniform cutting performance, making it ideal for controlled finishing of a wide range of restorative materials. The 220-grit equivalent micro-pyramidal abrasive design ensures consistent abrasive exposure throughout its lifespan. As the disc wears, fresh abrasive layers are continually exposed, delivering uniform surface quality without the drop-off seen in conventional abrasives. This makes the disc especially effective for refining chrome-cobalt alloys, titanium frameworks, zirconia surfaces, ceramic substructures, acrylic dentures, and orthodontic materials. The moderate-fine cutting action allows technicians to remove light imperfections, blend contours, reduce minor scratches, and prepare restorations for subsequent polishing stages. Its 2" diameter provides controlled handling in both broad and detailed regions, supporting high-precision adjustments during prosthetic fabrication. The PSA (Pressure-Sensitive Adhesive) backing ensures quick disc changes and strong, stable adhesion during rotational use, eliminating slipping and improving accuracy. It maintains cool grinding characteristics, reducing heat-related risks such as microcracking, acrylic whitening, or distortion of thermoplastic appliances. Designed for technicians seeking consistently smooth finishes with minimal effort, the 2" Trizact PSA 220 Sanding Disc provides long-lasting reliability, predictable results, and streamlined workflow efficiency, making it an essential tool for intermediate finishing in modern dental laboratories.
