1. Introduction: Purpose-Built for Demanding Environments
In precision instrument manufacturing facilities, flooring isn't just a surface-it's a critical component of operational efficiency, safety, and compliance. The Antimicrobial Polyurethane Anti-Static Self-Leveling Mortar Floor is engineered to meet the stringent demands of cleanrooms, electronics assembly lines, and high-tech laboratories where contamination control, electrostatic discharge (ESD) prevention, and durable performance are non-negotiable. This advanced flooring system integrates cutting-edge materials science with precision engineering to deliver a seamless, hygienic, and conductive surface that supports the rigorous workflows of modern industrial settings.
2. Technical Specifications & Composition
2.1 Core Material: Polyurethane Hybrid Mortar
- Binder System: Two-component aliphatic polyurethane resin with zero-VOC formulation, ensuring compliance with global environmental standards (e.g., FDA 21 CFR Part 177-2003 for food-grade facilities).
- Aggregates: Ultra-fine quartz sand and hydrophobic nano-silica particles for enhanced chemical resistance (pH 2-12) and abrasion resistance (ASTM D4060: <0.06g loss per 1000 cycles).
- Self-Leveling Properties: Thixotropic additives enable effortless application over complex subfloors, achieving a flatness tolerance of ±2mm/2m (DIN 18202).
2.2 Antimicrobial Technology
- Active Agents: Silver-ion (Ag+) or stabilizedm dioxide nanocapsules embedded within the matrix, providing continuous antimicrobial action against E. coli, S. aureus, and fungal species (ISO 22196: >99.9% reduction in 24h).
- Release Mechanism: Moisture-triggered release ensures long-term efficacy without leaching, maintaining ISO 846 compliance for hygiene-critical zones.
2.3 Anti-Static Performance
- Conductive Network: Carbon nanotubes (CNTs) or nickel-coated copper fibers dispersed uniformly to achieve a surface resistivity of (ESD S1.1: Class 1-3).
- Grounding System: Integrated copper grounding strips (1mm² cross-section) every 10m² to dissipate static charges safely (ESD STM97.1: <100V discharge).
