Patent number: 6559199Abstract: An elastomer system having biocide properties is described, useful, in particular, for dental impressions. An efficient system is provided for destroying microbes, without adversely affecting the crosslinking properties and the mechanical qualities of RTV 2 elastomers. Said system comprises an RTV 2 silicone, preferably SiH/SiVi polyaddition product and a biocide selected among active chlorine precursors, preferably among N-chloramines. The system may include functional additives (silicon fillers, alumina, paraffin, vaseline oil). As for the biocide, it can be provided with an antiseptic auxiliary adjuvant along with EDTA-type sequestering agents.Type: GrantFiled: April 30, 2001Date of Patent: May 6, 2003Assignee: Rhodia ChimieInventors: Christian Pusineri, Marco Del Torto

Patent number: 6559203Abstract: This invention relates to an organic foundry binder containing an alkyl resorcinol, or preferably a readily available mixture of alkyl resorcinols, and derivatives thereof. Preferably, the organic foundry binder is a furan binder. Foundry mixes are prepared by mixing the binder with a foundry aggregate. Foundry shapes (molds and cores) are prepared by shaping the mix and allowing it to cure to form a workable foundry shape. The invention also relates to the preparation of metal castings using the foundry shapes and the metal castings prepared with the foundry shapes.Type: GrantFiled: February 13, 2002Date of Patent: May 6, 2003Assignee: Ashland Inc.Inventors: David A. Hutchings, Heimo J. Langer, Ken K. Chang, Thomas E. Dando
