Product Description

 

 

 

 

 

 

 

1. Introduction 

In the demanding environment of precision instrument manufacturing, where sensitivity to contamination, static discharge, and surface imperfections is critical, the Anti-Bacterial Polyurethane Anti-Static Self-Leveling Mortar Floor emerges as a cutting-edge solution. Designed specifically for cleanrooms, laboratories, and production facilities in the precision engineering sector, this flooring system integrates advanced antimicrobial protection, electrostatic discharge (ESD) control, and seamless self-leveling properties to create a safe, hygienic, and high-performance workspace.

This mortar floor is engineered to meet the stringent requirements of ISO 14644 cleanroom standards and ESD Association (ESDA) guidelines, ensuring compatibility with sensitive electronic components, optical instruments, and medical devices. By combining polyurethane resin technology with conductive fillers and antimicrobial additives, it addresses three critical challenges in precision manufacturing: microbial contamination, static electricity buildup, and surface unevenness.

2. Technical Specifications & Composition 

Material Composition:

• Binder System: Two-component polyurethane resin with aliphatic isocyanates for chemical resistance and UV stability.
• Conductive Fillers: Homogeneously dispersed and silver-coated copper fibers for ESD control (surface resistivity: 1.0 × 10 to 1.0 × 10 Ω/sq).
• Antimicrobial Agents: Silver ion (Ag) and nano-zinc oxide (ZnO) additives, effective against Escherichia coli, Staphylococcus aureus, and fungi (ASTM E2180 compliance).
• Aggregate Matrix: Fine quartz sand (0.1-0.5 mm) and calcium aluminate cement for compressive strength (>30 MPa) and abrasion resistance.
• Self-Leveling Additives: Rheology modifiers and defoamers for smooth, bubble-free application (thickness range: 2-5 mm).

Performance Metrics:

 

Parameter	Value/Compliance
ESD Control	IEC 61340-5-1, ANSI/ESD S20.20
Antimicrobial Efficacy	ISO 22196 (≥99.9% reduction in 24 hours)
Chemical Resistance	Resistant to alcohols, ketones, and mild acids/alkalis
Thermal Shock	Withstands -40°C to +80°C cycles
Fire Rating	Class Bfl-s1 (EN 13501-1)
VOC Emissions	<10 g/L (compliant with LEED v4)

3. Core Advantages

3.1. Antimicrobial Protection
The integration of silver ions and nano-ZnO disrupts microbial cell walls and inhibits biofilm formation, critical in environments where sterile conditions are non-negotiable. Unlike topical coatings, the antimicrobial agents are embedded throughout the mortar matrix, ensuring lifelong efficacy even after repeated cleaning.

3.2. ESD Control for Safety & Product Integrity
Static discharge events can damage sensitive electronics (e.g., MEMS sensors, CMOS chips) and impair instrument calibration. This floor's conductive network provides a grounded pathway for electrostatic charges, with surface resistivity customizable to meet specific ESD control zones (EPA, ESA, or ESD).

3.3. Seamless, Self-Leveling Finish
The fluid-applied mortar fills cracks and imperfections, creating a continuous, joint-free surface. This reduces particle entrapment and simplifies cleaning protocols, aligning with ISO 14644-1 cleanroom classification standards.

3.4. Chemical & Mechanical Durability
Resistant to harsh disinfectants and heavy rolling loads (up to 3,000 kg/m²), the floor maintains integrity in high-traffic areas and aggressive cleaning regimens.

3.5. Rapid Installation & Low Downtime
The self-leveling formulation allows for fast application (1,000-1,500 m²/day per crew) and curing (walkable in 8-12 hours, fully cured in 72 hours), minimizing facility downtime.

4. Applications in Precision Instrument Factories 

• Cleanrooms (ISO Class 5-8): For semiconductor wafer fabrication, optical lens assembly, and medical device sterilization.
• Metrology Labs: Ensures stable environments for dimensional measurement instruments (CMMs, laser interferometers).
• Electronic Assembly Lines: Protects against ESD-induced failures in PCB testing and component mounting.
• Calibration Facilities: Maintains surface flatness (<0.1 mm/2m deviation) for precision balance scales and pressure sensors.
• Bio-Pharma Suites: Combines antimicrobial defense with chemical resistance to process fluids.

Case Study:
At a leading photonics manufacturer, this flooring reduced microbial contamination by 87% (post-installation swab tests) and eliminated static-related defects in laser diode assembly.

5. Installation Guidelines 

5.1. Substrate Preparation

• Moisture content: <4% (ASTM F1869) for concrete; <0.5% for epoxy-coated substrates.
• Primer application: Epoxy primer with conductive additives for non-conductive substrates.

5.2. Mixing & Application

• Mix components mechanically at 400-600 rpm for 3 minutes.
• Pour at 1.8 kg/m²/mm thickness; use serrated trowels for edge feathering.

5.3. Curing & Testing

• Ambient temperature: 15-30°C; RH: 30-70%.
• Conductivity verification via ESD wrist strap tester (ANSI/ESD STM12.1).

5.4. Post-Installation

• Burnish with diamond pads for gloss finish (optional).
• Apply conductive wax to welded joints in epoxy coatings.

6. Compliance & Certifications 

• Regulatory: FDA Title 21 CFR Part 177 (food-grade zones), REACH Annex XVII compliance.
• Standards: ISO 14001 (environmental management), ISO 45001 (occupational health).
• Third-Party Testing: UL Environment GREENGUARD Gold, TÜV Rheinland antimicrobial efficacy.

7. Maintenance & Sustainability 

• Cleaning: pH-neutral detergents; avoid abrasive pads.
• Recoating: Partial repairs possible without full replacement.
• Environmental Profile: 100% recyclable post-demolition; low embodied carbon (EPD certified).

8. Customization Options 

• Color: RAL shades for zone demarcation (e.g., red for ESD-critical areas).
• Texture: Smooth finish or slip-resistant aggregate broadcast.
• Conductivity: Adjusted via filler ratios for specific ESD control zones.

9. Conclusion 

The Anti-Bacterial Polyurethane Anti-Static Self-Leveling Mortar Floor redefines flooring solutions for precision instrument factories, harmonizing hygiene, safety, and operational efficiency.
