  • Hot melt adhesive
    Patent number: 6911491
    Abstract: A moisture reactive hot melt adhesive composition formed by admixing components including a polyisocyanate, an amorphous polyol, tri-C1-C6-alkyl citrate in the amount of 1.3 to 6% by weight based on the weight of said adhesive composition, and styrene/allyl alcohol copolymer having a hydroxyl number of 100-300 and Mn of 1,000-4,000 in the amount of 0.1 to 10% by weight based on the weight of said adhesive composition, wherein the ratio of NCO/OH groups of the components on an equivalents basis is from 1.05 to 2.5, the components being free from crystalline polyesters and polyethers and the components containing less than 1%, by weight based on the total weight of the components, of water is provided. Also a method for forming the adhesive composition and a method for bonding two substrates using the adhesive are provided.

  • Hot-melt adhesive
    Patent number: 6730738
    Abstract: A moisture-reactive hot-melt adhesive composition is provided. Particularly, a composition that includes a polyether polyol, a polyester polyol, a styrene/allyl alcohol copolymer, and a polyisocyanate. More particularly, the components are chosen so that the ratio of NCO/OH groups on an equivalents basis is from 1.8/1 to 3.0/1; the components contain less than 1% by weight of water; the weight ratio of polyether polyol to polyester polyol is at least 0.42; and the free NCO content is at least 5.5% by weight. Also provided are a method for forming the adhesive composition and a method for bonding substrates using the adhesive.
