Self-Leveling Epoxy Floor Coating - DFC 300

DRYFIX DFC-300 is engineered for use in a wide variety of industrial floor coatings and commercial environments, including:

• Industrial manufacturing facilities and factories.
• Warehouses and logistic centers.
• Retail stores and shopping malls.
• Indoor parking garages.
• Hospitals, laboratories, and clean rooms.
• It provides high mechanical strength and abrasion resistance, resulting in an easy-to-clean, hygienic surface. Additionally, it can be applied as a final topcoat within multi-layer epoxy flooring systems.

PRODUCT FEATURES (TECHNICAL SPECIFICATIONS)

APPLICATION INSTRUCTIONS

1. Concrete Surface Preparation

Proper surface preparation is crucial for system performance. The concrete substrate must be completely free from oil, dust, dirt, and icing. All contaminants that act as bond breakers—such as old paint chips, sawdust, oil residues, cement laitance, and loose or unsound concrete—must be mechanically removed via grinding or shot-blasting.

2. Mixing Procedure

The components are supplied in pre-weighed proportions. Pour Component B (Hardener) into Component A (Resin) and mix thoroughly for at least 3 to 4 minutes using a low-speed mechanical mixer (300-400 rpm). Pay strict attention to the 5:1 mixing ratio. Mix until a completely homogeneous, streak-free consistency is obtained. Once mixed, the product is immediately ready for application.

3. Coating System & Application

• Priming: The properly prepared surface must first be primed with DRYFIX DFC-100 Epoxy Primer. If the substrate is damp, DRYFIX DFC-108 Moisture Tolerant Epoxy Primer should be utilized.
• Application: The self-leveling coating process can commence 24 hours after the application of the primer. Depending on the specified coating thickness, pour the mixed DFC-300 onto the floor and spread it evenly using a notched trowel (typically with a 1 mm or 2 mm tooth pitch).
• De-aeration: Immediately after spreading, aggressively roll the wet coating with a spiked roller to release entrapped air bubbles and assist in leveling.

APPLICATION CONDITIONS & LIMITATIONS

• Concrete Strength: The concrete substrate to be treated must possess a minimum compressive strength of 25 N/mm² and a minimum pull-off adhesion strength to concrete of 1.5 N/mm².
• Absorbent Surfaces: On highly porous or absorbent concrete, continue applying the primer in successive coats until the substrate achieves sufficient resin saturation.
• Moisture Warning: Even after the full cure is achieved, the epoxy primer and topcoat can be damaged by negative-side hydrostatic pressure or rising dampness coming from the ground slab.
• Environmental Limits: Do not apply if ambient or substrate temperatures are below +10°C, or in highly humid environments where condensation may occur on the uncured film.

HEALTH, SAFETY, TRANSPORT, AND STORAGE

• For Professional Use Only. Always read and strictly observe the safety warnings on the product packaging and consult the Material Safety Data Sheet (MSDS) before use.
• Personal Protection: Do not inhale vapors. Avoid contact with skin and eyes. Do not swallow. Always use appropriate personal protective equipment (PPE) including chemical-resistant gloves, safety goggles, and respiratory masks.
• Hazard Prevention: Take necessary precautions to avoid fire and explosion hazards, as well as environmental pollution. Ensure the application area is well-ventilated during both the application and curing stages.
• Storage: Store in a dry, cool, and well-ventilated area in its original unopened packaging.
