A silicone rubber coating composition which cures into a silicone rubber having a tear strength of 25-50 kN/m and a peeling bond strength of 30-60 N/cm is suited for coating of hollow weave type air bags. A hollow weave type air bag coated with the coating composition can be instantaneously inflated while the bag prevents the silicone rubber film from being peeled from the base fabric, eliminates inflating gas leakage, and retains an acceptable inflation time.

Air bag coating composition

A silicone rubber coating composition which cures into a silicone rubber having a tear strength of 25&#x2013;50 kN/m and a peeling bond strength of 30&#x2013;60 N/cm is suited for coating of hollow weave type air bags. A hollow weave type air bag coated with the coating composition can be instantaneously inflated while the bag prevents the silicone rubber film from being peeled from the base fabric, eliminates inflating gas leakage, and retains an acceptable inflation time.

A composite cured product body is provided, which includes a first cured product part formed from a condensation reaction curable silicone rubber, and a second cured product part adhering to a surface of said first cured part formed from an addition reaction curable organopolysiloxane composition. The addition reaction curable organopolysiloxane composition includes:

Addition reaction curable organopolysiloxane composition

Disclosed is a silicone-based antifoam composition capable of exhibiting high defoaming activity even at a high temperature with excellent durability so as to be useful in dyeing processes. The composition comprises, as the principal ingredient, a polyoxyalkylene-modified polydimethylsiloxane, of which, different from conventional polyoxyalkylene-modified polydimethylsiloxanes, the polyoxyalkylene groups consist of two different types relative to the molar proportion of the oxyethylene units and oxypropylene units, in addition to a silicone oil compound of a silica filler, a poly(oxyethylene-oxypropylene) copolymer and low-molecular polydimethylsiloxane terminated at each molecular chain end with a dimethyl hydroxy silyl group.
