Abstract:
1. A reactive hot melt adhesive comprising: from about 10 to about 50 wt % of a high modulus silane modified liquid polymer having a backbone prepared from polyurethane, polyether, polyester, polyetherester, polyesterether, polyolefin, polycaprolactone, polybutadiene, polycarbonate, polyacetal, polyester amide, polythioether; from about 10 to about 30 wt % of a low modulus silane modified liquid polymer having a backbone prepared from polyurethane, polyether, polyester, polyetherester, polyesterether, polyolefin, polycaprolactone, polybutadiene, polycarbonate, polyacetal, polyester amide, polythioether; from about 20 to about 60 wt % of a tackifiers selected from the group consisting of rosin ester, aromatic tackifier or mixtures thereof; from about 20 to about 45 wt % of a silane reactive acrylic polymer; and from about 0.5 to about 5 wt % of a catalyst wherein the Young's modulus of cured high modulus silane modified polymer is greater than 50 psi and the sum of the total adhesive is 100 wt %.
