Patent number: 7119149Abstract: The present invention is directed to a high expansion two-component structural foam that expands to about twice its original volume while maintaining good cell structure. The foam of the present invention is based on epoxy resins. Each component of the foam system exhibits storage stability, e.g., no phase separation, yet reacts when combined to provide a cured material having exceptionally good compression strength and modulus. The blowing system used to prepare the foam produces a foam which is uniform in appearance and is essentially free of the large voids often found in conventional two-part thermosettable compositions, even when a relatively large mass is utilized.Type: GrantFiled: January 3, 2003Date of Patent: October 10, 2006Assignee: Henkel Kommanditgesellschaft AUFInventors: Gregory A.

Patent number: 6852803Abstract: A polymer dispersant for pigments based on a graft copolymer which contains a new type of urea functional group as the pigment anchoring group. The urea groups are attached to the graft copolymer by a convenient method which involves reaction of hydroxyl functional groups built in the graft copolymer with a diisocyanate that is capped at one end with ammonia or a primary or secondary amine. The reaction is convenient and clean. Substantial crosslinking or gelling of the polymer can be easily avoided by judicious selection of appropriate ingredients and processing conditions. These materials are effective in dispersing and stabilizing a wide range of pigments in solvent based systems and are particularly useful in forming pigment dispersions that are used in a variety of solvent borne coating compositions for automobiles and trucks, where they provide improved efficiency of pigment use, lower paint viscosity, and reduced emission of volatile organic solvent.Type: GrantFiled: June 3, 2002Date of Patent: February 8, 2005Assignee: E.
