Abstract: The invention relates to a fatty acid diamide-based rheology additive composition, which is pre-activated and pre-concentrated in fatty acid diamide, comprising: a) from 5% to 30% by weight of at least one fatty acid diamide based on 12 hydroxystearic acid and on a linear, in particular C5, C6 or C7, aliphatic diamine, b) from 70% to 95% by weight of at least one monofunctional (meth)acrylic reactive diluent comprising a cycloaliphatic group or several cycloaliphatic groups, the % being expressed relative to a)+b). It also relates to a process for preparing the composition and to the use thereof as a rheology additive in reactive binder compositions such as coating, moulding, composite material, anchor bolt or sealant compositions or photocrosslinkable compositions for stereolithography or for 3D printing of objects by inkjet.

Abstract: The present invention relates to a composition based on fatty acid diamide comprising: a) from 92% to 100% by weight of one or more fatty acid diamides, treated in situ by a neutralizing agent so as to reduce the residual amine content to a residual amine number, expressed in mg KOH/g, which remains less than 0.5, b) optionally, up to 8% by weight of at least one amorphous or semicrystalline oligomer with a Tg of greater than 60° C., with the sum of the % by weight a)+b) being equal to 100% by weight of the said diamide composition and with a) and b) being miscible as a blend.
