Patent number: 6448306Abstract: Certain butadiene and/or natural rubber articles, such as acrylonitrile-butadiene rubber (NBR), natural rubber, and derivatives thereof, that exhibit highly desirable long-term effective antimicrobial characteristics. Such formulations are intended to be vulcanized to provide solid or foam rubber articles which can be utilized in a variety of different applications. Preferably such butadiene rubber formulations comprise silver-based antimicrobial compounds. As such silver-based compounds are deleteriously affected by utilization of standard non-silicone-rubber curing agents, such as sulfur-based catalysts, the ability to provide such an effective antimicrobial vulcanized rubber article is rather difficult. However, the invention encompasses the utilization of different catalyst species that permit vulcanization and silver stability for long-term antimicrobial performance of the silver-based compounds.Type: GrantFiled: March 23, 2001Date of Patent: September 10, 2002Assignee: Milliken & CompanyInventors: John G. Lever, Geoffrey R. Haas, Bhawan Patel, William O. Burke, III, Robert C. Kerr

Patent number: 6428613Abstract: One object is to provide a curing accelerator which does not contain a lead soap, but has a curing property comparable to or surpassing that of a curing accelerator which contains a lead soap, and which does not color the coating. Another object is to minimize the amount of the cobalt soap if such is used. The curing accelerator for a resin having an unsaturated fatty acid group in its molecules contains a cobalt soap (A), a manganese soap (B), and an amino alcohol (C).Type: GrantFiled: June 2, 2000Date of Patent: August 6, 2002Assignee: Dainippon Ink and Chemicals Inc.Inventors: Shigeki Matsunaga, Sachiyo Shiiki
