Talc pleurodesis

Talc powder is puffed into the pleural cavity to cover the surface of the lung and the inside of the ribs. (Talc is similar to the talcum powder one uses in the bathroom but is prepared sterile to medical grade). The talc induces an inflammatory reaction which glues the lung to the inner surface of the ribcage.

Industrial Applications:

In traffic paints for better abrasion resistance. Improves stain resistance in Paint. Enhancement of smoothness at the time of application. The amount of Talc used in paints varies between 2 to 30%. Also the fineness of Talc used in paints varies between 100 to 20. The oil absorption of Talc used in Paints is between 40 to 60 gm per 100 gm.
