In modern construction, fire compartmentation and passive fire protection are critical to safeguarding life and assets. The ARC-318 Fire Resistant Insulation Grade Coating is an advanced solution engineered to enhance the fire rating of gypsum boards, concrete walls, and partition systems—up to 4 hours under fire exposure.
🔥 How ARC-318 Works
ARC-318 utilizes a fire-resistant insulation mechanism that activates at approximately 250°C, forming a thermal barrier that:
- Slows down heat transfer
- Prevents rapid temperature rise on the substrate
- Maintains structural stability of gypsum boards and walls
- Provides crucial evacuation time during fire incidents
Unlike conventional cladding or encasement systems, ARC-318 creates a continuous insulating layer, minimizing weak points and improving system reliability.
🏗️ System Composition
The ARC-318 system is a water-based, low VOC coating system consisting of:
- Base Coat (Primer): 2 coats
- Top Coat: 2 coats
This layered system allows flexible fire ratings depending on thickness and application.
⏱️ Fire Rating vs Material Consumption
- 30 mins: ~500 g/m²
- 60 mins: ~1000 g/m²
- 90 mins: ~1500 g/m²
- 120 mins+: Multi-layer system for extended ratings (up to 4 hours)
✅ Key Features & Benefits

⚙️ Why Choose ARC-318?
ARC-318 is not just a coating—it is a passive fire protection system designed to:
- Contain fire spread
- Protect structural elements
- Enhance building compliance with fire safety standards
By combining insulation, durability, and ease of application, ARC-318 offers a cost-effective alternative to traditional fireproofing methods.
