The present invention concerns a composition made from fatty acid diamide that comprises and in particular consists of : a) between 92 and 100% by weight of one or a plurality of fatty acid diamides, treated in situ with a neutralising agent, in such a way as to reduce the residual amine level to a residual amine index expressed in mg KOH/g that remains lower than 0, b) optionally, up to 8% by weight of at least one amorphous or semicrystalline oligomer having a Tg greater than 60°C, the sum of the weight % of a)+b) being equal to 100% of the weight of said diamide composition and a) and b) being miscible in a mixture. The invention also covers a method for preparing said composition made from diamide. The composition made from diamide of the invention is used as a rheology additive in cross-linkable compositions comprising, as the reactive component, a component sensitive to nucleophilic functions, such as amine, preventing the premature crosslinking of same. The compositions concern coatings, glues, sealants, sealing agents or moulding compositions. |
