H.B. Fuller 4189-3

H.B. Fuller 4189-3 energy-absorbing sound damping pad is a combination of energy-absorbing mastic material and an aluminum top layer that provides maximum sound damping. Extension and compression of the mastic damping material converts vibratory energy into heat, thus reducing the noise level of the damped substrate. The aluminum top layer maximizes this effect by redirecting any escaping vibratory energy back into the mastic layer.
