Patent number: 9051492Abstract: A primer composition including a toughening agent can be applied to a surface to be bonded using a separate curable adhesive composition. The primer composition toughens cured reaction products of the adhesive composition. In some embodiments the primer composition can also enhance reactivity of the curable adhesive composition.Type: GrantFiled: March 26, 2012Date of Patent: June 9, 2015Assignee: Henkel IP & Holding GmbHInventors: Shabbir Attarwala, Ifeanyi Chris Broderick, Prakash S. Patel

Patent number: 8377195Abstract: A wearing compound slurry comprising an inorganic binder, ceramic particles, ceramic powder, diluent and optionally filler and discontinuous fibers. The slurry is applied to a wearable surface and exposed to heat to remove diluent and cure the wearing compound into a hard layer. The cured wearing compound layer remains intact after exposure to extremely high temperatures.Type: GrantFiled: September 12, 2011Date of Patent: February 19, 2013Assignee: Henkel CorporationInventors: Prakash S. Patel, Shabbir Attarwala

Patent number: 7723275Abstract: An anti-seize composition which is non-flowable and dimensionally stable at temperatures greater than about 120° F. and dispensable at room temperature without the application of heat is provided. The composition includes a solid anti-seize lubricant, such as of metallic copper, metallic nickel, metallic aluminum, metallic lead, metallic zinc, graphite, calcium oxide, calcium carbonate, calcium fluoride, calcium stearate, lithium, molybdenum disulfide, boron nitride, barium sulfate. or combinations thereof. The anti-seize lubricant is dispersed in a carrier which is a solid at about room temperature. The carrier includes a grease with an ASTM D 217 penetration at 25° C. from about 200 to about 400 mm, a matrix material, and a naphthenic petroleum oil having a viscosity of less than about 300 SUS at 100° F. and having an API gravity at 60° F. from about 23 to about 25. The matrix material is a polymeric material. Optionally, a refined petroleum wax may also be included.Type: GrantFiled: July 13, 2007Date of Patent: May 25, 2010Assignee: Henkel CorporationInventors: Prakash S. Patel, Shabbir Attarwala

Publication number: 20090188269Abstract: A high pressure connection and method for making a high pressure connection. The method includes applying a primer composition to one distal joint portion, applying an anaerobically curable composition to the other distal joint portion; sliding one distal joint portion into the other distal joint portion and curing the anaerobic composition to maintain the second distal joint portion within the first distal joint portion thereby forming the high pressure connection. The method does not use plastic deformation of the first or second distal joint portions after the step of sliding. The method is advantageously useful for making high pressure connections in gas compression or refrigeration systems.Type: ApplicationFiled: January 23, 2009Publication date: July 30, 2009Applicant: Henkel CorporationInventors: Shabbir Attarwala, Prakash S. Patel
