FCA10 Fast Cure Industrial Adhesive is not a contact cement - It is waterproof and will bond Acoustiblok® to itself, wood, metal, and most other surfaces. Acoustiblok must be held in place while curing.
Very fast cure time, varying with temperature and humidity. Due to the unique properties of Acoustiblok, most adhesives will not maintain a bond to the Acoustiblok, and the bond may release after a few days depending on the temperature.
NOTE: Most other adhesives will not bond to Acoustiblok.
Acoustiblok® is a 1/8 inch thick proprietary viscoelastic polymer material with a high density mineral content, heavy and yet extremely flexible. As sound waves cause the Acoustiblok material to flex, internal friction occurs (isothermal/adiabatic) and the acoustical energy is dissipated into undetectable trace amounts of heat. A one 1/8 inch layer of Acoustiblok in a standard wall will result in more sound reduction than 12 inches of poured concrete.
