Nitoflor Sicaltop: Silicon Carbide Floor Hardener Technical Details

Product Overview

Nitoflor Sicaltop is a factory-blended powder floor hardener specifically engineered for concrete floor applications. It represents a specialized construction product designed to enhance the durability and safety characteristics of newly laid concrete surfaces in demanding industrial environments.

Composition and Key Components

Nitoflor Sicaltop is composed of carefully selected and graded materials that work synergistically to deliver superior floor performance. The product formulation includes:

• Silicon carbide aggregates - providing exceptional hardness and slip-resistant properties
• Alumina-based aggregates - contributing to overall hardness and durability
• Portland cement - serving as the binding matrix
• Special additives - improving workability and ensuring proper hydration

This controlled factory-blending approach ensures consistency and reliability across batches, eliminating the variability associated with site-batched materials.

Hardness and Durability Properties

The aggregate components demonstrate exceptional hardness characteristics:

• Silicon carbide hardness: 13 on Moh's modified scale
• Alumina-based aggregate hardness: 12 on Moh's modified scale

These properties make Nitoflor Sicaltop exceptionally resistant to wear and polishing, ensuring the surface maintains its slip-resistant characteristics even under sustained traffic conditions.

Abrasion Resistance Performance

Abrasion resistance testing by the Australian Mineral Development Laboratories demonstrated outstanding performance. Concrete floors treated with Nitoflor Sicaltop at the recommended dosage achieved greater than 200% improvement in abrasion resistance compared to untreated concrete floors. This significant enhancement in wear resistance extends floor service life considerably in high-traffic applications.

Slip Resistance Characteristics

A defining advantage of Nitoflor Sicaltop is its integrated slip-resistant design:

• Contains silicon carbide to provide excellent non-slip properties
• Slip resistance increases with use as the cement surface surrounding the grains is worn away by normal traffic
• Maintains effective slip resistance even when wet
• Non-staining and chemically inert, ensuring aesthetic appeal and durability
• Provides monolithic bonding with the base concrete

Application Method and Coverage

Nitoflor Sicaltop utilizes a straightforward shake-on method of application, applied directly to freshly laid concrete slabs during the finishing process. The product is applied at varying rates depending on traffic conditions:

The product is applied between 2 to 4 kg/m² depending on anticipated service conditions and traffic intensity.

Physical and Mechanical Properties

Compressive Strength: Nitoflor Sicaltop achieves approximately 95 MPa compressive strength at 28 days, meeting demanding structural requirements for industrial flooring.

Water Permeability: Simulated permeability tests under pressures up to 340 kPa demonstrated significant reduction in water permeation compared to untreated concrete.

VOC Content: The product contains 7g/litre VOC content, representing an environmentally conscious formulation.

Color Availability: Supplied in natural concrete Grey color variant.

Environmental and Health Considerations

Nitoflor Sicaltop is classified as RCS (Respirable Crystalline Silica) Hazard Free in accordance with the Australian Inventory of Industrial Chemicals, containing less than 0.1% RCS. This classification reflects the product's safety profile for workers during application.

Ideal Applications

Nitoflor Sicaltop is ideally suited for industrial areas subject to the heaviest traffic conditions, including:

• Loading bays and trucking lanes
• Warehouse floors
• Car parks and parking structures
• Repair workshops and machine shops
• Factory production areas
• Any environment requiring extremely hard-wearing, abrasion and impact-resistant surfaces

Key Performance Advantages

• Provides extremely strong, hard-wearing surface with excellent abrasion and impact resistance
• Forms monolithic bond with base concrete for superior adhesion
• Non-metallic, chemically inert aggregate that does not rust
• Economical to apply with reduced placement time (up to 20% faster than site-batched alternatives)
• Easy to trowel into fresh concrete surfaces
• Non-rusting surface ideal for diverse industrial environments

Product Supply and Storage

Supply Format: Nitoflor Sicaltop Grey is supplied in 20-kilogram bags (product code: FC602040-20KG).

Shelf Life: The product maintains a shelf life of 18 months when stored in original, undamaged packaging. Storage in high temperature and high humidity locations may reduce shelf life.

Storage Requirements: Store in dry conditions in original packaging to maintain product integrity.
