Classification of Polyurethane Floor Coatings
Polyurethane floor coatings, with their diverse performance, have large market demand and rich varieties. The following introduces the main classifications of polyurethane floor coatings.
I. Classification by Dispersion Medium
Divided into three types: solvent-based, solvent-free, and water-based.
- **Solvent-based polyurethane floor coatings**: As early-used coatings, they contain solvents that cause environmental impacts and are currently subject to usage restrictions.
- **Solvent-free polyurethane floor coatings**: Excellent in environmental performance, non-toxic and eco-friendly, available in both rigid and flexible product types.
- **Water-based polyurethane floor coatings**: Include one-component and two-component types. Among them, two-component water-based polyurethane floor coatings are highly popular floor materials in the market. With water as the dispersion medium, they minimize VOCs (Volatile Organic Compounds) emissions while integrating the excellent construction process, decorative appearance, physical and mechanical properties, and chemical resistance of two-component solvent-based polyurethane coatings.
II. Classification by Product Usage Method
Divided into one-component and two-component types.
- **One-component polyurethane floor coatings**: Contain only one component, with relatively poor wear resistance and corrosion resistance.
- **Two-component polyurethane floor coatings**: Composed of Component A and Component B, with excellent comprehensive performance. Currently, most polyurethane floor coatings on the market fall into this category.
III. Classification by Coating Functional Characteristics
- **Anti-slip floor coatings**: Polyurethane itself has good anti-slip performance and can be directly used in scenarios with basic anti-slip requirements. For environments with higher anti-slip requirements, special high-anti-slip coatings can be prepared by mixing with materials such as carborundum or corundum to further enhance the floor's anti-slip performance.
- **Wear-resistant floor coatings**: The core advantage of this type of coating lies in its super wear resistance. Even under long-term wear from repeated vehicle rolling and high-frequency human traffic, it can still keep the floor intact. Therefore, it is particularly suitable for areas with high floor wear such as factory workshops and warehouses.
- **Anti-static floor coatings**: Possess efficient anti-static capabilities, which can quickly discharge static electricity generated on the floor, effectively preventing static accumulation from interfering with or damaging electronic equipment and precision instruments. They are widely used in static-sensitive places such as electronic manufacturing factories and scientific research laboratories.
