The invention relates to a method for the additive manufacturing of a silicone elastomer article using a 3D printer. The invention also relates to a crosslinkable silicone composition for the additive manufacturing of a silicone elastomer article.

Method for the additive manufacturing of a silicone elastomer article

The general field of the invention is that of silicone coating compositions, in particular those of two-component or multi-component type, that can be crosslinked by polyaddition or hydrosilylation reactions to produce a support coated by a silicone elastomer as a thin layer. These silicone compositions, when they are crosslinked, are suitable, inter alia, as coatings, for example for the protection or mechanical reinforcement of various textile substrates such as for example fibrous, woven, knitted or nonwoven supports. The targeted objective is to provide a silicone elastomer coating composition that can be crosslinked by polyaddition reactions and that is useful in particular for applications in the field of inflatable safety bags for vehicles, or airbags, having, after crosslinking, optimum properties in terms of adhesion, thinness, lightness and crease and abrasion resistance, but also good mechanical properties. This silicone coating composition should also be easy to use and to apply.
