Hardwire 3SX-21.5-12 High Density Tape Product Information -:- For detailed product information, please contact sales. -: # Hardwire® 3SX-21.5-12 High Density Tape ## Product Overview Hardwire® 3SX-21.5-12 High Density Tape is a premium industrial-grade abrasive tape engineered for maximum material removal efficiency and extended service life in demanding surface preparation applications. The product designation "3SX-21.5-12" indicates its three-layer reinforced construction, 21.5 oz/yd² (730 g/m²) high-density abrasive loading, and 12-inch standard working width. This heavy-duty tape represents the highest performing product in the 3SX series, designed specifically for aggressive stock removal, rapid surface leveling, and high-productivity operations where time efficiency and abrasive longevity are paramount. Developed through proprietary grain orientation technology and advanced bonding chemistry, this tape delivers up to 40% faster cutting rates and 50% longer service life compared to conventional high-density abrasives. The precisely controlled high-grain-density configuration ensures maximum abrasive-to-surface contact while maintaining heat dissipation characteristics through optimized grain spacing. ## Technical Composition & Construction ### Multi-Layer Architecture 1. **Backing Material:** Heavy-duty polyester-film-polyester-scrim laminate (Type X-weight - 5.0 mil composite) 2. **Reinforcement Layer:** Cross-woven fiberglass scrim embedded between polyester films 3. **Make Coat:** High-performance phenolic resin with thermal stabilizers and anti-loading agents 4. **Abrasive Layer:** Premium ceramic alumina or zirconia alumina grains 5. **Size Coat:** Reinforced phenolic resin with toughening modifiers 6. **Backside Treatment:** Calendered anti-static coating with pressure-sensitive adhesive compatibility ### Abrasive Specifications * **Primary Abrasive Types:** * Ceramic Alumina (Grade 5) - Standard high-performance option * Zirconia Alumina (Grade 6) - Premium option for toughest applications * Silicon Carbide - Available for specialized non-ferrous applications * **Grit Range:** P16 to P180 (coarse to medium) * **Grit Density:** 21-22 oz/yd² (710-745 g/m²) nominal loading * **Grain Concentration:** 85-90% surface coverage (high-density closed coat) * **Grain Bonding:** Electrostatic and mechanical deposition with dual-resin bonding system * **Grain Shape:** Precision-shaped and sized for optimal cutting geometry ### Physical Dimensions & Packaging * **Width:** 12 inches (304.8 mm) ±0.8 mm tolerance * **Length:** 25 yards (22.86 meters) per roll (heavy-duty construction) * **Total Thickness:** 0.45-0.60 mm depending on grit size * **Core:** 3-inch (76 mm) industrial polymer core with metal end caps * **Roll Diameter:** 10 inches (254 mm) maximum * **Packaging:** Vacuum-sealed in moisture-barrier foil with desiccant * **Weight per Roll:** 8.5-9.5 kg (depending on grit) ##
