Coating liquid for loudspeaker cones (black). For better internal damping, reduction of partial oscillation and linearization of the frequency response. Prevents bleaching of the cone. Especially suited for cone speakers with paper cones. Water-soluble until hardened completely.
Contents: 50 ml - enough for quite a few speakers depending on size and surface material.

Do not dilute, apply sparingly, allow to dry then test. Extra coats can be applied.
