ALTIC 050 FR Intumescent Over FRC Sheet

Introduction

Fire safety is a critical aspect of modern construction, infrastructure, and industrial facilities. Building materials such as Fiber Reinforced Cement (FRC) sheets are widely used for walls, partitions, and structural applications. While FRC sheets offer strength and durability, they require additional protection against fire hazards. ALTIC 050 FR Intumescent Over FRC Sheet is an advanced fire-retardant coating solution engineered to meet these challenges. It provides superior fire protection while maintaining the structural integrity of the substrate.

Certified Fire Protection

ALTIC 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 ALTIC 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.
