GFS012 GORLEX Fire Retardant Coating for Steel Mastic

1. Product Identification: Gorlex GFS 012

The Gorlex GFS 112 is a specialized fire-retardant mastic coating specifically engineered for the protection of structural steel. Unlike standard thin-film coatings, this mastic formulation provides a heavy-duty, high-build barrier designed to maintain the structural integrity of steel components during high-temperature fire events.

Brand Heritage and Manufacturing

• Manufacturer: Gopal Fire and Safety.

• Brand: Gorlex.

• Origin: Produced under the “Make in India” initiative.

• Location: Based in Amreli, Gujarat.

2. Chemical and Structural Composition

The GFS 112 utilizes a “New & Improved Formula” designed for industrial durability. As a mastic coating, its chemical architecture differs significantly from decorative paints:

Mastic Formulation

Industrial steel mastics like GFS 112 are typically formulated with high solids content to allow for thick-film application in a single pass. This creates a dense, resilient layer that acts as both a physical shield and a chemical fire barrier.

Fire Retardant Mechanism

While the specific chemical additives remain proprietary to the “New & Improved Formula,” fire-retardant mastics generally operate through one or more of the following mechanisms:

• Endothermic Decomposition: The coating absorbs heat energy, slowing the temperature rise of the underlying steel.

• Dilution of Combustible Gases: Release of non-flammable vapors (like water vapor or nitrogen) to starve the flame of oxygen.

• Thermal Insulation: The thick-build mastic layer acts as a permanent thermal insulator, preventing the steel from reaching its critical failure temperature (typically around 550°C).

3. Technical Specifications

The following technical parameters define the Gorlex GFS 112 application profile:

4. Key Performance Characteristics

Structural Steel Protection

Structural steel is vulnerable to fire; as it heats, it loses its load-bearing capacity, leading to potential building collapse. GFS 112 is designed to provide a critical time window for evacuation and firefighting by insulating these vital components.

Industrial Durability

As an industrial mastic, the product is engineered for harsh environments:

• Corrosion Inhibition: Provides a protective seal against moisture and industrial pollutants that cause rust.

• Impact Resistance: The thick, cured film is more resistant to mechanical damage compared to standard fire-retardant paints.

• Adhesion: Formulated for superior bonding to prepared steel surfaces, ensuring the fire protection layer does not delaminate under thermal stress.

5. Application Methodology

For GFS 112 to achieve its rated fire protection performance, strict adherence to application protocols is necessary.

Surface Preparation

1. Cleaning: Steel must be free from mill scale, rust, oil, and grease.

2. Blasting: Typically requires abrasive blasting to a standard (such as Sa 2.5) to provide the necessary surface profile for mastic adhesion.

3. Priming: Depending on the specific system requirement, a compatible anti-corrosive primer may be applied before the GFS 112 mastic.

Application Techniques

• Airless Spray: Given the high viscosity of mastic coatings, heavy-duty airless spray equipment is the preferred method for achieving a uniform, high-build finish.

• Trowel or Brush: Used for small-scale applications or for reinforcing joints and complex geometries.

6. Safety, Storage, and Compliance

The GFS 112 is packaged in 20-liter containers, designed for professional industrial use.

Storage Requirements

• Store in a cool, dry environment.

• Keep containers tightly sealed when not in use to prevent the “New & Improved Formula” from skinning or curing in the tin.

• Protect from extreme temperatures and direct sunlight to maintain chemical stability.
