Product Description

 

 

1. Introduction to Chemical-Resistant Polyurethane Self-Leveling Mortar Floor

In critical environments where hygiene, durability, and chemical resistance are paramount, the Chemical-Resistant Polyurethane Universal Self-Leveling Mortar Floor emerges as a cutting-edge solution. Designed specifically for disinfection areas-including hospitals, laboratories, pharmaceutical facilities, food processing plants, and cleanrooms-this flooring system combines advanced polyurethane technology with self-leveling mortar properties to deliver a seamless, high-performance surface.

This product is engineered to withstand harsh chemical exposure, thermal shock, and heavy mechanical stress while maintaining its integrity and aesthetic appeal. It meets the stringent requirements of international hygiene standards (e.g., ISO 14698, GMP, HACCP) and is ideal for areas requiring frequent disinfection with aggressive agents such as bleach, alcohols,  and quaternary ammonium compounds.

2. Key Features and Advantages

2.1 Unmatched Chemical Resistance

• Broad-Spectrum Protection: The polyurethane matrix is cross-linked to resist acids, alkalis, solvents, and oxidative agents (pH 2-12).
• Disinfectant Compatibility: Withstands repeated exposure to hospital-grade disinfectants without degradation, discoloration, or surface erosion.
• Long-Term Durability: Retains mechanical properties even after years of exposure to aggressive cleaning regimens.

2.2 Seamless, Hygienic Surface

• Eliminates Bacterial Traps: The self-leveling formulation creates a continuous, joint-free surface, reducing penetration points for pathogens.
• Easy Cleanability: Smooth, non-porous finish allows for effortless removal of bio-contaminants, blood, and organic residues.
• Cove Base Integration: Seamlessly transitions to walls, eliminating crevices and ensuring full enclosure of the disinfection zone.

2.3 Superior Mechanical Performance

• High Compressive Strength: Withstands heavy loads from equipment, foot traffic, and rolling carts (typical compressive strength > 40 MPa).
• Impact Resistance: Absorbs shocks from dropped instruments or machinery without cracking.
• Abrasion Resistance: Resists wear from scrubbing machines, trolleys, and abrasive cleaners (Taber abrasion loss < 100 mg).

2.4 Thermal Stability

• Wide Temperature Tolerance: Functions optimally from -40°C to 120°C, suitable for cold storage, autoclave rooms, and heated processing zones.
• Thermal Shock Resistance: Withstands sudden temperature changes without delamination or surface defects.

2.5 Aesthetic and Functional Versatility

• Customizable Colors: Available in a range of RAL or Pantone shades to match facility branding or zoning requirements.
• Anti-Slip Finishes: Optional aggregate additives provide R9-R13 slip resistance for wet or oily environments.
• Static-Dissipative Options: Additives can be incorporated to meet ESD standards (surface resistivity: 10-10 Ω).

2.6 Rapid Installation and Low Downtime

• Self-Leveling Technology: Fast-curing formulation reduces installation time by 30-50% compared to traditional epoxy systems.

• Minimal Disruption: Single-component or pre-mixed kits simplify application, requiring no specialist tools.

• Quick Return to Service: Cure times as low as 4-6 hours at 20°C, with full chemical resistance achieved in 24-48 hours.
