Patents by Inventor Lowell G. Lindquist

Lowell G. Lindquist has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Versatile processes for preparing and using novel composite particles in powder coating compositions
    Patent number: 7622072
    Abstract: Methodology for constructing composite particles from ingredients comprising two or more particulate components. The resultant particles are usefully incorporated into powder coating compositions. The approach also finds utility in other applications, including but not limited to the food, drug, and cosmetics industry. Fluidized particles are subjected to an intense, but relatively brief heating event. This causes associated particles to fusingly assemble into fused composite clusters.
    Type: Grant
    Filed: January 12, 2006
    Date of Patent: November 24, 2009
    Assignee: Valspar Sourcing, Inc.

  • Hot melt adhesive composition
    Patent number: 5534575
    Abstract: Hot melt adhesives which include at least 5% of a thermoplastic elastomer block copolymer having a Vicat softening temperature of at least 60.degree. C. and a melting point of at least 100.degree. C., have improved thermal resistance properties and can be applied with conventional hot melt application equipment at temperatures of between about 149.degree. C. and about 204.degree. C. The adhesives are particularly suited to use in above-the-belt locations in automobile interiors and in furniture bonding. Especially suitable thermoplastic elastomers are polyether-polyester and polyether-polyamide segmented polymers with melting points above 149.degree. C. Hot melt adhesives based on these thermoplastic elastomers can be formulated to provide a range of properties including pressure sensitive properties and contact adhesive properties.
