Abstract: The present description relates to a method of manufacturing an interconnection structure of an integrated circuit intended to be encapsulated in an encapsulation resin in contact with a first surface of a protection layer. The protection layer is resting on a first surface of the interconnection structure. The interconnection structure comprising copper interconnection elements extending at least partly through an insulating layer and flush with the first surface of said interconnection structure. The manufacturing method includes a step of structuring of the protection layer or a step of forming of the protection layer with a structuring. The structuring step or the forming step is adapted to structuring the first surface of the protection layer in the form of an alternation of ridges and troughs.

Abstract: The present invention discloses an intumescent coating composition, a method for coating a substrate with said composition, a substrate coated with said composition, an article comprising said substrate, and a method to provide fire protection for a battery and/or an article comprising a battery in particular a vehicle comprising a lithium ion battery.

Abstract: The present invention relates to an intumescent coating composition comprising: (a) a polyepoxy-functional compound; (b) a beta-hydroxy ester of (meth)acrylic acid comprising a plurality of beta-hydroxy (meth)acrylic ester groups; (c) a compound bearing a plurality of functional groups that are reactive with the epoxy groups of the polyepoxy-functional compound (a) and the (meth)acrylic ester groups of the beta-hydroxy ester of (meth)acrylic acid comprising a plurality of beta-hydroxy (meth)acrylic ester groups; and (d) a compound providing an expansion gas upon thermal decomposition; wherein compounds (a) to (d) differ from each other, a method for coating a substrate with said intumescent coating composition and to a substrate at least partially coated with a coating deposited from said intumescent coating composition.

Abstract: An intumescent coating composition includes a binder resin, an acid-generating agent, and an expansion agent. The expansion agent can be meso-lactide, a polylactide or other polyester, a polysulfone, a polycarbonate, a 1,1-di-activated vinyl compound, or an addition polymer of a 1,1-di-activated vinyl compound, or a combination of any thereof.
