Abstract
The invention relates to a fatty amide which is a di- or triamide based on a polyether diamine or triamine which can be used as organogelator and in particular as rheology additive, said amide comprising a specific mixture of hydroxylated fatty acids and short hydroxylated acids. The invention also relates to a formulation composition using said fatty amide as rheology additive and to its use with this aim in coating, adhesive or PVC plastisol compositions and in particular transparent or non-transparent mastic compositions. Said rheology additive has the advantage of not needing a specific activation process before use, in contrast to the other known fatty amide additives based on hydrogenated castor oil derivatives.
