  • Patent number: 10174231
    Abstract: A hot-melt adhesive composition comprises 35 wt % to 40 wt % of petroleum resin, 10 wt % to 14 wt % of polyester elastomer resin, 10 wt % to 14 wt % of ethylene vinyl acetate resin, 14 wt % to 19 wt % of polyether polyol, 15 wt % to 21 wt % of polyester polyol, 8 wt % to 10 wt % of methylene diphenyl diisocyanate, and 0.1 wt % to 0.5 wt % of an amine catalyst, wherein the hot-melt adhesive composition has a melt viscosity of 20,000 cps to 50,000 cps as measured at 150° C.

  • Publication number: 20160369137
    Abstract: An adhesive composition includes an acryl copolymer having a carboxyl group, and a silane compound represented by Formula 1 or 2, thereby it is possible to exhibit excellent initial adhesiveness and adhesive durability under severe conditions, and prevent the substrate from being torn due to a decrease in adhesiveness by water applied thereto, and the adhesive from remaining on the substrate during peeling-off the adhesive layer, as well as after drying, the adhesive layer may exhibit favorable adhesiveness again, thus being used for re-bonding.

  • Publication number: 20160369135
    Abstract: An adhesive composition includes an acryl copolymer having a hydroxyl group and a weight average molecular weight of 800,000 to 1,500,000 g/mol; an isocyanate-based cross-linking agent, an aliphatic hydrocarbon solvent having 6 to 10 carbon atoms, and an acid additive having a molecular weight of 40 to 100 g/mol, thus low viscosity characteristics may be maintained for a long period of time, and thereby stirring and coating may be easily performed while it does not require an excess of diluted solvent.
