Novel
airbag coating compositions comprising at least two separate and distinct
layers are provided. The first layer (base coat), being in contact with the
airbag surface, comprises a composition of at least one
coating material which may comprise up to 30% by parts of the total amount of material in the first layer of a
silicone resin which provides excellent adhesion, excellent tensile strength, and overall lower cost than standard
silicone airbag coating materials. The second layer, being a coating for the first layer, provides excellent reinforcement and blocking characteristics to permit
effective potential long-term storage and optimum use upon the occurrence of a collision. Such a second layer (topcoat) is preferably a
silicone material but may also be selected from the group consisting of homopolymer and coplymer resins based on
ethylene, propylene, acrylates, methacrylates, vinyl esters,
acrylic acid,
methacrylic acid, polyurethanes, polyamides, and
inorganic materials such as
talc, silica,
silicate,
calcium carbonate,
alumina, and the like. This two-layer
system permits excellent strength and blocking properties to prevent undesired adhesion between portions of the target airbag when stored as well as to prevent seam
combing at relatively low cost due to the materials and the relatively low amount required for the topcoat. An airbag fabric coated with this inventive two-layer
system is also contemplated within this invention.
