Patent number: 9944830Abstract: This invention relates to cyanoacrylate-containing compositions that include, in addition to the cyanoacrylate component, a rubber toughening component, which is substantially clear and colorless and which is substantially free of release agents and anti-oxidants known to impair the fixture speeds and shelf life stability of cyanoacrylate compositions to which they are added. As a result, the inventive rubber cyanoacrylate adhesive compositions demonstrate improved properties, such as fixture speed, strength and shelf life under accelerated aging conditions.Type: GrantFiled: October 12, 2016Date of Patent: April 17, 2018Assignee: Henkel IP & Holding GmbHInventors: Shabbir Attarwala, Rosa Matilde Davila, Benjamin M. Surowiecki, Jr., Stan Wojciak, Roger James Grismala, Ling Li

Patent number: 7064155Abstract: A radiation-curable composition which includes a cyanoacrylate component or a cyanoacrylate-containing formulation; a metallocene component; a photoinitiator; and a luminescent and/or fluorescent dye.Type: GrantFiled: January 31, 2003Date of Patent: June 20, 2006Assignee: Henkel CorporationInventor: Stan Wojciak
-
Patent number: 6906112Abstract: A radiation-curable composition which includes a cyanoacrylate component or a cyanoacrylate-containing formulation; a metallocene component; and a polymerizingly effective amount of a photoinitiator to accelerate the rate of cure is provided.Type: GrantFiled: March 12, 2002Date of Patent: June 14, 2005Assignee: Henkel CorporationInventors: Stan Wojciak, Shabbir Attarwala
-
Patent number: 6890399Abstract: Polymerizable compositions for use in or as adhesives, sealants and/or coatings are disclosed herein. The compositions include a (meth)acrylate component together with a dye substantially dissolved in the (meth)acrylate component which imparts a first color to the (meth)acrylate component. Upon curing, a resultant cured composition has a second color. The invention also relates to a method of detecting substantially full cure of the polymerization of the compositions.Type: GrantFiled: January 18, 2002Date of Patent: May 10, 2005Assignee: Henkel CorporationInventor: Stan Wojciak

Patent number: 6867241Abstract: The present invention relates to a radiation-curable composition which includes a cyanoacrylate component or a cyanoacrylate-containing formulation, a metallocene component, a hydrogen abstraction photoinitiator, and hydrogen donor component to enhance the activity of the hydrogen abstraction photoinitiator.Type: GrantFiled: January 31, 2002Date of Patent: March 15, 2005Assignee: Henkel CorporationInventors: Stan Wojciak, Shabbir Attarwala, John T. O'Connor, S. Peter Pappas

Patent number: 6833196Abstract: A cyanoacrylate adhesive composition having an acrylic monomer toughening agent. Preferably, the acrylic monomers are selected from the group consisting of methyl methacrylate, butyl acrylate, cyclohexyl acrylate, isobornyl acrylate, and combinations thereof. A useful amount of acrylic monomers is about 1.0% by weight to about 10.0% by weight, preferably about 1.0% by weight to about 5.0% by weight, and more preferably about 2.0% by weight to about 5.0% by weight.Type: GrantFiled: June 24, 2002Date of Patent: December 21, 2004Assignee: Henkel CorporationInventor: Stan Wojciak

Patent number: 6689826Abstract: Cyanoacrylate composition, having a cure indicator within the composition, is disclosed herein. The cyanoacrylate composition is “self-indicating” with respect to its ability to allow the end user to visually inspect the composition to determine whether, and the extent to which, cure has occurred. The composition includes a cyanoacrylate component, and a dye dissolved in the cyanoacrylate component. The cyanoacrylate composition has an initial color, oftentimes colorless or substantially so to the naked eye, and when cured, the cured cyanoacrylate composition has a different or second color. Observation of the second or different color is indicative that cure has occurred and the extent of the color change can be used to determine the degree of cure that has occurred.Type: GrantFiled: January 18, 2002Date of Patent: February 10, 2004Assignee: Henkel Loctite CorporationInventor: Stan Wojciak
