Gorlex GFS 104 – Advanced Intumescent Fire Retardant Paint

Comprehensive Product Description

The Gorlex GFS 104 represents the pinnacle of passive fire protection technology. Engineered for high-stakes industrial and commercial environments, this Advanced Intumescent Paint is designed to “stop fire in its tracks.” Unlike standard fire-retardant coatings, an intumescent paint undergoes a dramatic chemical transformation when exposed to temperatures exceeding a specific threshold. It expands to many times its original thickness, creating a dense, insulating layer of carbonaceous char.

This “char” acts as a highly effective thermal barrier, protecting the underlying substrate—whether it be structural steel, wood, or specialized composite materials—from reaching critical failure temperatures. By insulating the structure, GFS 104 provides essential additional time for building occupants to evacuate safely and for emergency services to respond, potentially preventing a total structural collapse.

Featuring our New & Improved Formula, the GFS 104 is optimized for superior adhesion and a high expansion ratio. It is a vital safety component for airports, sports arenas, refineries, and high-rise buildings. Beyond its life-saving capabilities, it dries to a sleek, professional finish that can be top-coated to match any architectural color scheme, ensuring that safety and design go hand-in-hand.

Proven Intumescent Power

The GFS 104 is formulated with high-purity chemical blowing agents and carbon donors. When the heat hits, the coating reacts instantly to form a robust “meringue-like” foam. This foam is incredibly resistant to thermal conductivity, keeping the heat away from the core structural elements.

Structural Integrity Insurance

In a fire, steel begins to lose its load-bearing capacity at approximately $550°\text{C}$. The GFS 104 is specifically designed to delay this “critical temperature” point for up to 120 minutes. This delay is often the difference between a repairable building and a total loss.

Durable and Versatile Finish

While its primary job is safety, the GFS 104 is also built to last. It is resistant to mechanical impact and environmental degradation. Its smooth texture allows for the easy application of decorative topcoats, making it suitable for exposed structural steel in modern “open-ceiling” office designs or industrial lofts.

Application Best Practices:

1. Preparation: Surfaces must be primed with a compatible anti-corrosive primer (like GFS 110) and be free of moisture.

2. Monitoring: Use a Wet Film Thickness (WFT) gauge during application to ensure the specific thickness required for your fire-rating goal is met.

3. Environment: Avoid application if the relative humidity is above 80% or if the surface temperature is within $3°\text{C}$ of the dew point.
