Publication number: 20100261136Abstract: The invention relates to a dental composition comprising a hardenable powder to be used in a process for retraction of dental tissue. The invention also relates to a kit of parts comprising the dental composition comprising a hardenable powder, a hardening agent, optionally a handpiece of a powder jet device, optionally a powder jet device, and optionally retraction caps. In a further aspect, the invention relates to a method for retracting dental tissue comprising the steps of applying a dental composition comprising a hardenable powder with a powder jet device into the sulcus between soft and hard dental tissue, applying a composition comprising a hardening agent either before or after the previous step, leaving the dental composition in the sulcus for a time sufficient to effect retraction of the soft dental tissue and removing the dental composition from the sulcus.Type: ApplicationFiled: December 9, 2008Publication date: October 14, 2010Inventors: Christoph Schulte, Andreas R. Maurer, Thomas Klettke, Ruediger Hampe, Ingo R. Haeberlein

Patent number: 7799885Abstract: A curable composition and a process for using the curable composition within a grating-coupled waveguide (GCW) sensor are disclosed. The composition can be used for facile replication of optical components, specifically those used in a label-independent detection system where operation of the waveguide is dependent on the detailed formation of micro and nano size patterns. The photo or electron beam curable composition has low viscosity (?500 cPs) and cures to an optically clear material with high glass transition temperature (?70° C.), low shrinkage on cure, low outgassing, and low extractables.Type: GrantFiled: November 30, 2005Date of Patent: September 21, 2010Assignee: Corning IncorporatedInventors: Paul J. Shustack, Kimberly S. Wayman

Patent number: 7799853Abstract: Disclosed is a pressure sensitive adhesive composition characterized by containing an ionic liquid and a polymer which contains, as a monomer unit, 0.1-10% by weight of a (meth)acrylate with a hydroxyalkyl group having 3-12 carbon atoms. The present invention provides a pressure sensitive adhesive composition which is excellent in antistatic property of a no-electrification-prevented adherend upon peeling, and has reduced staining of an adherend and is excellent in adhesion reliance. Also disclosed is an antistatic pressure sensitive adhesive sheet or surface-protecting film prepared using the composition. Also disclosed is an antistatic pressure sensitive adhesive sheet or surface-protecting film prepared using the composition.Type: GrantFiled: September 5, 2006Date of Patent: September 21, 2010Assignee: Nitto Denko CorporationInventors: Natsuki Ukei, Tatsumi Amano, Masahiko Ando
