The ratings on silicones and quartz producer Momentive Performance Materials Inc. reflect its satisfactory business risk profile as a leading global silicones producer and its very high debt leverage following Apollo Management's December 2006 acquisition of 90% of the company from General Electric Co. (GE) for $3.9 billion. Wilton, Conn.-based Momentive is the world's second-largest silicone producer, representing about 90% of its revenues. The remainder of revenues comes from the sale of quartz, primarily for semiconductors. Silicones are used in a wide variety of applications, including construction, transportation, personal care, electronics, and agriculture. They are generally used as an additive, providing or enhancing attributes such as resistance (to heat, ultraviolet light, or chemicals), lubrication, adhesion, or viscosity.
