Abstract
An air bag coated with a cured organopolysiloxane composition, characterized in that the air bag is top coated with an antifriction coating comprising at least one solid lubricant dispersed in an organic polymer binder.
Claims10
An air bag coated with a cured organopolysiloxane composition, wherein the cured organopolysiloxane composition is directly top coated with an antifriction coating comprising a siloxane polyether wetting agent, an epoxysilane adhesion promoter, non-ionic surfactant, aluminum trihydrate, and solid lubricant comprising talc and polytetrafluoroethylene, wherein the solid lubricant is dispersed in an urethane polymer binder, wherein the antifriction coating comprises 5 to 30% of the talc on a dry coat weight basis;
- 20 to 90% of the solid lubricant, including the talc, on a dry coat weight basis;
- 3 to 50% of the urethane polymer binder on a dry coat weight basis;
- and 5 to 55% of the aluminum trihydrate on a dry coat weight basis.
A process for coating an air bag or air bag fabric in which the bag or fabric is coated with an organopolysiloxane composition to form an organopolysiloxane base coat, wherein the organopolysiloxane base coat is directly top coated with an antifriction coating composition comprising an aqueous dispersion of a siloxane polyether wetting agent, an epoxysilane adhesion promoter, non-ionic surfactant, aluminum trihydrate, and solid lubricant comprising talc and polytetrafluoroethylene, wherein the solid lubricant is dispersed in an urethane polymer binder, wherein the antifriction coating comprises 5 to 30% of the talc on a dry coat weight basis;
- 20 to 90% of the solid lubricant, including the talc, on a dry coat weight basis;
- 3 to 50% of the urethane polymer binder on a dry coat weight basis;
- and 5 to 55% of the aluminum trihydrate on a dry coat weight basis.
An antifriction coating composition comprising a siloxane polyether wetting agent, an epoxysilane adhesion promoter, non-ionic surfactant, aluminum trihydrate, and solid lubricant comprising talc and polytetrafluoroethylene, wherein the solid lubricant is dispersed in an urethane polymer binder, wherein the antifriction coating comprises 5 to 30% of the talc on a dry coat weight basis;
- 20 to 90% of the solid lubricant, including the talc, on a dry coat weight basis;
- 3 to 50% of the urethane polymer binder on a dry coat weight basis;
- and 5 to 55% of the aluminum trihydrate on a dry coat weight basis.
