  • Fatty diamide additive composition preconcentrated and pre-activated in a reactive diluent
    Patent number: 11485834
    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.
