Mortite putty

Mortite putty is a type of putty that consists of titanium dioxide as its main ingredient. The putty has a specific gravity of 1.34, and has the characteristics of being pliable, off white and giving off very little odor. The material stays soft and pliable for an extended period of time.

Mortite putty can be used as caulking around conventional windows installed in conventional wooden or metal frames (see glazing). It is also used as a form for epoxy work, since epoxy does not adhere to this material.

Mortite putty has also been applied to the metallic structure supporting the magnet for a dynamic speaker to cut unwanted resonance of the metal structure, leading to improved speaker performance. It has also been used as a sonic damping material in sensitive phonograph components.
