Polyurethane Sandblasted Anti-Slip Mortar Floor for Cold Storage
Product Overview
The Polyurethane Sandblasted Anti-Slip Mortar Floor is a specialized industrial flooring solution engineered for cold storage facilities, freezer rooms, refrigerated warehouses, and other low-temperature environments where safety, durability, and thermal resilience are critical. Combining a high-strength polyurethane resin matrix with a sandblasted anti-slip texture, this system provides exceptional traction, chemical resistance, and thermal shock stability, ensuring worker safety and operational efficiency in subzero conditions.
Key Features & Benefits
1. Superior Anti-Slip Performance in Cold Environments
- Sandblasted Texture for Maximum Grip: The floor's aggressively textured surface, created via sandblasting or broadcast aggregate application, delivers a high coefficient of friction (CoF) even when wet, icy, or contaminated with frost.
- Reduced Slip & Fall Risks: Meets or exceeds safety standards (e.g., DIN 51130 R12-R13, pendulum test ≥36 SRV) to minimize workplace accidents in slippery cold storage zones.
2. Extreme Temperature Resilience
- Thermal Shock-Proof Design: Withstands rapid temperature fluctuations (-40°C to +15°C) and prolonged exposure to subzero conditions without cracking, crazing, or delamination.
- Flexible Yet Durable: Polyurethane's inherent elasticity prevents brittleness in cold environments, ensuring long-term structural integrity under heavy foot traffic and rolling loads.
3. Chemical & Moisture Resistance
- Cold-Storage-Specific Formulation: Resists damage from refrigerant leaks, defrosting cycles, condensation, and exposure to brine solutions, deicing chemicals, and food-grade disinfectants.
- Seamless, Waterproof Barrier: Eliminates water ingress into the substrate, preventing freeze-thaw damage and mold growth.
4. Impact & Abrasion Resistance
- Heavy-Duty Load Bearing: Withstands impacts from pallet jacks, forklifts, and dropped frozen goods without surface indentation or cracking.
- Wear-Resistant Finish: High-build polyurethane mortar resists abrasion from foot traffic, equipment movement, and ice buildup removal.
5. Hygienic & Easy-to-Clean Surface
- Cove Base & Jointless Design: Enables seamless transitions to walls and drains, preventing bacterial growth and simplifying sanitation in food-grade cold storage.
- Low-Maintenance Cleaning: Resists staining and ice adhesion, allowing efficient removal of frost, spills, and debris with pressure washing or steam cleaning.
6. Customizable for Specific Needs
- Color-Coded Zoning: Customizable colors (e.g., blue for frozen food zones, red for defrosting areas) improve workflow efficiency and compliance with HACCP/FSMA standards.
- ESD/Conductive Options: Static-dissipative (ESD) or conductive formulations available for cold storage of electronics or explosive materials.
7. Eco-Friendly & Low-VOC
- Sustainable Formulation: Solvent-free, low-odor, and compliant with REACH, RoHS, and LEED standards, ensuring worker health and environmental safety.
- Fast Curing for Minimal Downtime: Cures in 12-24 hours (walkable) and 48-72 hours (full load) at subzero temperatures, reducing facility shutdowns.
