Silent Seal® Mine Ventilation Air Sealant quickly and efficiently creates airtight seals on and around doors, fans, ventilation devices, brattice, metal and block stoppings.

Silent Seal® spray foam sealant is a two component mine ventilation sealant that expands and seals in seconds to quickly and efficiently seal, insulate, fill, coat and sound dampen many areas above ground and underground. Created exclusively for mining, this product adheres to coal, steel, concrete, wood and most other substrates. Silent Seal® spray foam sealant is also ideal for harsh weather climates where the temperature may be too low for standard Handi-Foam®products. The high flow rate of the Handi-Gun® dispensing unit allows for increased productivity, accurate metering, flow control and reduced waste.

Silent Seal® NA has been deemed suitable by the Mine Safety and Health Administration (MSHA) for use by mine operators without wearing a Self-Contained Breathing Apparatus or a Supplied Air Breathing Apparatus. MSHA’s testing concluded that Fomo’s Silent Seal® does not create a harmful environment for workers when used with Fomo’s patented Handi-Gun® dispensing unit. Silent Seal® also passed MSHA testing for ASTM E-162, a surface flammability test.
