Abstract
The present invention relates to a polyamide composition comprising a polyamide which is the poly condensation product of an acid component and an amine component, the acid component comprising, per mole of acid component; −30 to 50 mol. % of fatty acid dimer(s); −30 to 50 mol. % of aliphatic dibasic acid(s); −0 to 10 mol. % of chain limiter(s); the amine component comprising, per mole of amine component; −10 to 40 mol. % of cycloaliphatic diamine(s); and −50 to 80 mol. % of aliphatic diamine(s) comprising 3 to 12 carbon atoms); −0 to 15 mol. % of polyetheramine(s); said polyamide composition having; —a viscosity less than or equal to 4 Pa·s at 185° C.; and —a softening temperature ranging from 150° C. to 170° C.
