Matte Polyurethane Anti-Static Self-Leveling Mortar Floor for Electronics Factories
Product Overview
The Matte Polyurethane Anti-Static Self-Leveling Mortar Floor is a specialized industrial flooring solution engineered for electronics manufacturing facilities, combining electrostatic discharge (ESD) protection, seamless self-leveling aesthetics, and chemical resilience. Formulated with conductive polyurethane resins and matte-finish aggregates, this system dissipates static charges to <10 Ω (surface) and <10 Ω (volume), meeting ANSI/ESD S20.20 and IEC 61340-5-1 standards. Ideal for cleanrooms, semiconductor fabrication, PCB assembly, and ESD-sensitive storage zones, it ensures device safety, operator comfort, and compliance with stringent electronics industry regulations.
Key Features & Benefits
1. Advanced Anti-Static Performance

- Grounding Grid Integration: Compatible with copper tape or conductive mesh for site-wide static dissipation.
2. Matte, Non-Glare Aesthetics
- Low-Sheen Finish: 15-20 gloss units (GU) at 60° (ASTM D523) reduces light reflection in LED/LCD assembly zones.
- Uniform Appearance: Self-leveling to ±2 mm tolerance over 100 m² areas, eliminating trowel marks.
- Color Customization: Available in static-dissipative shades (light gray, beige, and custom RAL/Pantone matches).
3. Heavy-Duty Chemical & Solvent Resistance
- Resists Electronics-Grade Chemicals:
- Acids: 5% (etching), 10% Citric acid (cleaning).
- Alkalis: 5% Ammonium hydroxide (photoresist stripping).
- Solvents: and N-Methyl-2-pyrrolidone (NMP).
- Blood & Protein Resistance: Repels flux residues, solder paste, and conductive epoxy without staining.
4. Seamless, Hygienic & Easy-to-Clean Design
- Cove Base Integration: Forms a 120 mm radius coved skirt with walls to eliminate particle traps.
- Non-Porous Surface: Certified ISO 14644-1 Class 5 (100,000 particles/m³ ≥0.5 μm) for cleanroom compatibility.
- Low-VOC Cleaning: Supports IPA wiping, deionized water rinsing, and CO snow blasting.
5. Thermal & Mechanical Durability
- Thermal Shock Tolerance: Withstands -20°C to +80°C (e.g., reflow ovens, cold storage for components).
- Impact Resistance: Absorbs 300 lb-ft (407 J) impacts (ASTM D2794) without cracking.
- Abrasion Resistance: Taber abrasion loss <20 mg (CS-17 wheel, 1,000 cycles) per ASTM D4060.
6. Fast Installation & Rapid Return to Service
- Pot Life: 30-40 minutes at 20°C, enabling 1,000+ m²/day applications.
- Curing Time:
- Light Traffic: 10 hours (walkable).
- Full Load: 48 hours (pallet jacks), 7 days (heavy machinery).
- Moisture Tolerance: Installable on concrete with up to 97% RH (ASTM F2170) via vapor-retardant primers.
