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

Patent number: 6673873Abstract: A substantially transparent, moldable, thermoplastic multipolymer composition comprising a methyl methacrylate copolymer containing a predominant amount of methyl methacrylate and a minor amount of one or more ethylenically unsaturated monomers; and an effective amount of a polyetheresteramide to enhance the electrostatic charge dissipation of the copolymer. The polyetheresteramide has a refractive index within about 0.005 units of the refractive index of the copolymer. The composition, when subjected to injection molding, is such that the injection-molded composition exhibits a haze of not greater than about 25% and a light transmission of at least about 60%. Preferably, the composition includes an impact modifier which also has a refractive index within about 0.005 units of the refractive index of the copolymer. The composition may also include a minor amount of a polyethylene glycol having a weight average molecular weight of about 2,000 to about 10,000.Type: GrantFiled: August 25, 1999Date of Patent: January 6, 2004Assignee: Cyro IndustriesInventor: Daniel Zimmerman
