Patent number: 7169840Abstract: In a process for the manufacture of aqueous floor covering adhesives without the addition of solvents, high-boiling solvents, or plasticizers and with the use of a non-carboxylated styrene/butadiene (SBR) dispersion and of an agent providing initial adhesion, a melt of the agent providing initial adhesion, for example a resin with a melting point of 45 to 98° C., is added to the SBR dispersion under high shear forces for the purpose of obtaining a durably stable emulsion which provides not only high initial adhesion, but also high final strength.Type: GrantFiled: October 8, 2002Date of Patent: January 30, 2007Assignee: Ardex GmbHInventors: Jochem Billecke, Rudiger Oberste-Padtberg, Thomas Wanke, Kenneth A. Tarczewski, David Allen Smith

Patent number: 7067585Abstract: A hot melt adhesive composition is based on an isotactic polypropylene random copolymer (RCP). The composition contains about 4%–50% by weight of the RCP copolymer, about 20%–65% by weight of a compatible tackifier, about 0%–40% by weight of a plasticizer, about 0%–3% by weight of a stabilizer, about 0%–40% by weight of a wax, and optionally about 0%–60% by weight of an atactic poly-?-olefin (APAO). The adhesive composition may be used in a number of applications such as, for example, in disposable nonwoven hygienic articles, paper converting, flexible packaging, wood working, carton and case sealing, labeling and other assembly applications.Type: GrantFiled: October 28, 2002Date of Patent: June 27, 2006Assignee: Bostik, Inc.Inventors: Baoyu Wang, Monina Dadap Kanderski, Lacretia A.
