Abstract
Hot melt adhesive compositions containing amine and acid terminated polyamide resins, optionally curable when combined with epoxy resins, wherein the amine component of the polyamide resin contains (i) 1,2-diaminopropane, (ii) a piperazine-containing diamine, and optionally, (iii) polyetherdiamines; the polyamide resins may be acid or amine terminated, and are characterized by having an acid plus amine number of up to 40, preferably up to 30, and more preferably up to 20; the adhesive compositions are useful in a number of applications and have good strength while exhibiting flexibility and low tackiness.
