PU-Cement Heavy Duty Flooring System

Polyurethane-Cement Flooring System for Extreme Industrial Environments

Chimatech PU-Cement Heavy Duty is a high-performance seamless flooring system designed for environments exposed to intense mechanical, chemical, and thermal stress. It is developed for industrial facilities where standard epoxy floors are not sufficient.

The system includes:

• Primer: Chimaprime CE – high-strength epoxy bonding primer

• Main layer: Self-levelling polyurethane-cement mortar (Heavy Duty grade)

Key Advantages

Exceptional Thermal Resistance

• Service temperature range: from –25°C to +90°C (at 6 mm thickness)

• Suitable for areas exposed to thermal shock and hot water cleaning

• Anti-slip version resistant up to +120°C (at 9 mm thickness)

Outstanding Mechanical Strength

• Compressive strength: 58 N/mm²

• Flexural strength: 20 N/mm²

• Tensile strength: 10 N/mm²

• Adhesion to concrete: >1.5 N/mm² (concrete failure)

• High abrasion resistance

Suitable for forklift traffic, heavy machinery, and continuous industrial use.
