Pyrocoustic® Sealant is a one part, acrylic emulsion. It is designed to resist the passage of fi re, smoke, air and sound. The sealant will intumesce and form a char when exposed to the heat of a fire that prevents the passage, of fire and smoke. In normal use it will maintain the sound reduction on index of a structure.
Pyrocoustic® Sealant does not emit halogenated by-products under fire conditions, and contains no raw materials known to have an estrogenic effect in the environment. It has good unprimed adhesion to a wide variety of common building substrates.
