CHEMGUARD C364 3×6 AR-AFFF (Alcohol Resistant Aqueous Film-Forming Foam) Concentrate combines fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. This synthetic foam concentrate is intended for firefighting applications at 3% solution on hydrocarbon fuels and at 6% solution on polar solvent fuels in fresh, salt, or hard water.

CHEMGUARD C364 foam solution utilizes three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance:

• The foam blanket blocks oxygen supply to the fuel.
• Liquid drains from the foam blanket and forms either:
  • An aqueous film on a hydrocarbon fire, or
  • A polymeric membrane on a polar solvent fire which suppresses the vapor and seals the fuel surface.
• The water content of the foam solution produces a cooling effect for additional fire suppression.

CHEMGUARD C364 Concentrate is a non-Newtonian fluid that is both pseudoplastic and thixotropic; therefore, dynamic viscosity will decrease as shear increases.

The CHEMGUARD C364 3×6 AR-AFFF Concentrate formulation contains short-chain, C-6 fluorochemicals manufactured using a telomer-based process that does not produce PFOS.

Approvals, Listings, and Standards

CHEMGUARD C364 3×6 AR-AFFF Concentrate is designed in accordance with the National Fire Protection Association (NFPA) Standard 11 for Low-, Medium-, and High-Expansion Foam. The concentrate is approved, listed, qualified under, or meets the requirements of the following specifications and standards:

• UL Standard 162, Foam Liquid Concentrates
• ULC S564, Category 2 Foam Liquid Concentrates

Application

CHEMGUARD C364 3×6 AR-AFFF Concentrate is intended for use on both types of Class B fires: hydrocarbon fuels with low water solubility, such as crude oils, gasolines, diesel fuels, and aviation fuels; and polar solvent fuels with appreciable water solubility, such as methyl and ethyl alcohol, acetone, and methyl ethyl ketone. It may also be used in conjunction with dry chemical agents to provide even greater fire suppression performance.

CHEMGUARD C364 Concentrate can be ideal fixed, semi-fixed, and emergency response firefighting applications such as:

• Fuel or chemical storage tanks
• Industrial chemical and petroleum processing facilities
• Truck/rail loading and unloading facilities
• Flammable liquid containment areas
• Docks and on-board marine systems
• Mobile equipment
