Update time : 2025-08-22

Polyurethane super-wear-resistant floor coating is a high-performance flooring material achieving extreme durability through molecular innovation. Its core value lies in the revolutionary integration of 

abrasion resistance, impact tolerance, and chemical resistance – delivering long-term protection for industrial environments.

I. Technical Principle: Triple-Structure Synergy

Nano-Ceramic Reinforcement Layer

Micro-grade hard aggregates (SiC/Al₂O₃) boost surface hardness to Mohs 7 (equal to quartz), forming an anti-wear shield.


Elastic Polyurethane Matrix

Specialized PU molecular chains provide dynamic flexibility, absorbing 80% impact energy (no cracks from 1-ton drops).

Chemical Bonding Layer

Penetrating primer reacts with concrete for permanent substrate adhesion.

*Lab Data: Abrasion cycles >2,500 (4× national standard), no cracking at -30°C impact.*

II. Performance Advantages

10× Longer Lifespan: Withstands 200+ daily forklift passes in warehouses for 10+ years


Impact Resistance: No damage from 1-ton objects at 1m height


Chemical Immunity: Resists concentrated H₂SO₄/NaOH (48h zero penetration)


Extreme-Temperature Stability: Performance maintained from -30°C to 120°C


Inherent Slip Resistance: Wet COF ≥0.65 with no degradation in oily conditions


III. Core Applications

Heavy-Duty Industrial Zones: Manufacturing workshops, logistics warehouses (prevents dusting/delamination)


Harsh Chemical Environments: Electroplating/pharmaceutical plants (replaces traditional epoxy)


Subzero Facilities: Cold storage, fresh-food processing areas (eliminates freeze-cracking)


Ultra-Clean Rooms: Food/electronics factories (seamless & antibacterial)


IV. Selection & Installation Guidelines

Substrate Requirements: Concrete ≥C25, moisture <8%


Coating Design:

Light-duty: 1.5mm (primer + topcoat)

Heavy-duty: 3mm (mortar + topcoat)


Application Conditions: Temp >5°C, humidity <85%


Maintenance: Neutral cleaners only; avoid strong acid/alkali exposure
