SC 050 FR Intumescent Over FRC Sheet

Certified Fire Protection

SC 050 FR Intumescent Over FRC Sheet is rigorously tested and certified by the Government of India’s National Test House, Ghaziabad for 120 minutes of fire resistance. The system complies with IS 14856-2000 and has been certified for blistering, flaking, chalking, cracking, and color/gloss retention. Additionally, it meets international standards such as ASTM E-162, ASTM E-662, ASTM E-84, and ASTM D-1360, and aligns with NFPA 703 requirements for fire-retardant coatings. Its proven performance makes it one of the most reliable intumescent systems available in India.

How It Works

The effectiveness of SC 050 lies in its intumescent action. When the coated FRC sheet is exposed to temperatures above 200°C, the coating expands to form a thick, insulating foam layer. This charred foam barrier:

• Prevents heat transfer to the substrate
• Cuts off oxygen supply to the surface
• Stops the spread of flames
• Reduces smoke and toxic gas emission

This multi-layered defense system ensures enhanced fire resistance, buying crucial evacuation and response time during emergencies.

Application Guidelines

• Surface Preparation
  • Ensure the FRC sheet is clean, dry, and free from dust or contaminants.
  • Apply SC FR Primer (solvent-based for metals, water-based for cement surfaces).
• Coating Application
  • Apply seven coats of SC 050 FR with an interval of 4 hours between coats.
  • Coating thickness: Ensure a total DFT of at least 1.8 mm for 2-hour fire protection.
  • Application via airless spray is recommended for uniform finish.
• Topcoat
  • For areas exposed to humidity, apply two coats of SC FR Topcoat to enhance durability and longevity.
• Maintenance
  • Damaged or worn areas should be abraded, cleaned, and recoated.
  • Reapplication is recommended after fire exposure to maintain protection.
