1. A binder composition comprising at least:
a binder base selected from the group consisting of an oil, a bitumen base, a pitch, a clear binder, and mixtures thereof,
an acid compound of general formula (I):
R—(COOH)z (I)
wherein R represents a linear or branched, saturated or unsaturated chain comprising from 4 to 68 carbon atoms and z is an integer ranging from 2 to 4, and
an amide an amide compound of general formula (II):
R′—(NH)nCONH—(X)m—(NHCO)p(NH)n—R″ (II)
wherein:
the R′ and R″ groups, which may be identical or different, represent a saturated or unsaturated and linear, branched or cyclic hydrocarbon-based chain comprising from 1 to 22 carbon atoms which optionally comprises heteroatoms, C5-C24 hydrocarbon-based rings and/or C4-C24 hydrocarbon-based heterocycles comprising one or more heteroatoms, and R″ may be H;
the X group represents a saturated or unsaturated and linear, cyclic or branched hydrocarbon-based chain comprising from 1 to 22 carbon atoms which is optionally substituted and which optionally comprises heteroatoms, C5-C24 hydrocarbon-based rings and/or C4-C24 hydrocarbon-based heterocycles comprising one or more heteroatoms,
n, m and p are integers having a value of 0 or 1, independently of one another,
the composition comprises between 0.1% and 5% by weight of the acid compound, relative to a total weight of the binder composition, and between 0.1% and 5% by weight of the amide compound, relative to the total weight of the binder composition, and
the acid compound and the amide compound are present in an acid compound:amide compound weight ratio ranging from 10:1 to 1:16, said binder composition being in a form that is solid under cold conditions and divided.
