MACt Defoamer

MACt Defoamer is a premium defoaming additive formulated to remove unwanted air bubbles in GFRC (Glass Fibre Reinforced Concrete) mixes. By eliminating trapped air, MACt Defoamer enhances density, strength, and overall durability—making it an essential component for professionals seeking high-performance concrete products. Whether you’re aiming for greater resilience in challenging weather conditions or a more polished, defect-free appearance, MACt Defoamer delivers reliable results that extend the lifespan and quality of your concrete elements.

Key Features & Benefits

1. Enhanced Density & Strength
   • Improved Load-Bearing Capacity: Removing air bubbles increases the concrete’s overall density, boosting its ability to handle heavy loads and endure harsh environments.
   • Higher Compressive Strength: Achieve stronger, more reliable GFRC products that meet demanding structural requirements.
2. Reduced Permeability
   • Longer Lifespan: Fewer entrapped air bubbles lead to less porosity, mitigating moisture infiltration and subsequent cracking or spalling.
   • Improved Durability: Concrete becomes more water-resistant, preserving structural integrity and preventing early deterioration.
3. Weathering Resistance
   • Withstands Freezing & Thawing: Defoamed mixes resist weather-induced damage, ensuring stable performance and fewer repairs.
   • Suitability for Harsh Environments: Ideal for outdoor applications in extreme climates, reducing long-term maintenance costs.
4. Superior Workability
   • Streamlined Construction: Air-free mixes are easier to spread, pump, and finish, saving on labour and project timelines.
   • Efficient Placement: Consistent flow throughout the mix improves handling, reducing the likelihood of voids or uneven settling.
5. Better Aesthetics
   • Smooth, Uniform Finish: Minimises honeycombing, voids, and surface blemishes, delivering a professional, polished appearance.
   • Ideal for Decorative Concrete: Perfect for GFRC applications where visual quality is a priority—facades, countertops, panels, and more.

Recommended Dosage & Usage

• Dosage Range: 0.1–0.2% of the total water content in the mix.
• Mixing Instructions:
  1. Add MACt Defoamer to the Water: Introduce the product directly into your batch water.
  2. Thoroughly Blend: Ensure consistent dispersion by mixing well before adding cementitious materials.
  3. Does Not Replace Water: Adjust your total water quantity as needed while respecting the defoamer dosage range.
