    • This invention relates to novel airbag coating compositions comprising at least two separate and distinct layers. 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 aging characteristics to prevent degradation of the first layer. Such a second layer (topcoat) is preferably a silicone material. This two-layer system permits excellent strength and aging properties to prevent seam combing at relatively low cost due to the inexpensive basecoat 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.
    • 本发明涉及包含至少两个分离和不同层的新型气囊涂料组合物。 第一层(底涂层)与气囊表面接触。 包括至少一种涂料的组合物,其可以包含至少30%的硅树脂第一层中的材料的总量,其提供优异的粘合性,优异的拉伸强度和总体上比标准硅橡胶安全气囊涂层更低的成本 材料 作为第一层的涂层的第二层提供优异的增强和老化特性以防止第一层的退化。 这样的第二层(面漆)优选为硅树脂材料。 由于廉价的底涂层材料和面漆所需的相对较低的量,这种双层系统允许优异的强度和老化性能以相对较低的成本防止缝合。 本发明还涵盖了涂有本发明的双层系统的气囊织物。
