Publication number: 20240010795Abstract: The present invention provides an imide composition obtainable by a process which comprises the steps of: (a) reacting a dianhydride with a diamine in the presence of a solvent at a temperature in the range of from 20-80° C., wherein the molar ratio of the dianhydride (A) to the diamine (B) is in the range of from 0.25-4 (A/B), thereby forming an imide precursor; and (b) subjecting at least part of the imide precursor as formed in step (a) in the presence of a solvent to a heat treatment which is carried out at a temperature in the range of from 80-150° C. to convert at least part of the imide precursor into an imide, thereby forming the imide composition.Type: ApplicationFiled: June 29, 2023Publication date: January 11, 2024Inventors: Amra Cenanovic, Frank Fiddelaers, Remko Thijssen, Albert van den Kommer, Roel van der Zwaan

Patent number: 11851396Abstract: The present invention provides a preservative composition to prevent and/or reduce corrosion on a metal surface comprising an anhydride-derived amide and an oil and/or a solvent, wherein the anhydride-derived amide is present in an amount in the range of from 0.01-50 wt %, based on the total weight of the preservative composition. The invention also provides a preservative composition comprising in addition a sulfonate composition; a metal article having a coating thereon which coating comprises the present preservative composition; and the use of the present preservative composition to prevent and/or reduce corrosion on a metal surface.Type: GrantFiled: May 7, 2020Date of Patent: December 26, 2023Assignee: Aktiegolaget SKFInventors: Amra Cenanovic, Frank Fiddelaers, Remko Thijssen, Albert van den Kommer, Roel van der Zwaan

Publication number: 20200354522Abstract: An imide composition obtainable by providing (a) reacting a dianhydride with a diamine in the presence of a solvent at a temperature in the range of from 20-80° C. The molar ratio of the dianhydride to the diamine is from 0.25-4, forming an imide precursor; and (b) subjecting the imide precursor as formed in step (a) in the presence of a solvent to a heat treatment carried out at a temperature from 80-150° C. to convert the imide precursor into an imide, thereby forming the imide composition. Also, a preservative composition including the present imide composition; a metal article having a coating that provides the present preservative composition; a process for preparing the imide composition; the use of the present imide composition to prevent and/or reduce false brinelling in a roll bearing system; and the use of the present preservative composition to prevent and/or reduce false brinelling in a roll bearing system.Type: ApplicationFiled: March 18, 2020Publication date: November 12, 2020Inventors: Amra Cenanovic, Frank Fiddelaers, Remko Thijssen, Albert van den Kommer, Roel van der Zwaan

Publication number: 20200354313Abstract: A sulfonate composition obtainable by a process in which a naphthalene ring-containing sulfonic acid is reacted with an amine in the presence of a base oil at a temperature in the range of from 20-80° C. The molar ratio of the sulfonic acid to the amide is in the range of from 0.2-3 (S/A). The invention also provides a preservative composition comprising the present sulfonate composition; a metal article having a coating thereon which coating comprises the present preservative composition; a process for preparing the sulfonate composition; the use of the present sulfonate composition to prevent and/or reduce corrosion in a roll bearing system; and the use of the present preservative composition to prevent and/or reduce corrosion in a roll bearing system.Type: ApplicationFiled: March 9, 2020Publication date: November 12, 2020Inventors: Amra Cenanovic, Frank Fiddelaers, Remko Thijssen, Albert van den Kommer, Roel van der Zwaan

Patent number: 9341611Abstract: A kit for testing grease includes components for testing consistency, oil bleed characteristic and contamination. Consistency of the grease is tested by compressing a sample of the grease between two surfaces (e.g., glass plates), measuring the extent of spread, and comparing the measured spread to a calibrated reference. Oil bleed characteristic is tested by placing a quantity of the used grease on a test medium, heating the test sample, measuring a dimension of the grease quantity on the heated test sample, and determining the bleed characteristic of the used grease by comparing the dimension of the grease quantity to a reference. A contamination test may be performed by further compressing the consistency sample and inspecting the sample both by the naked eye and with a microscope.Type: GrantFiled: November 24, 2010Date of Patent: May 17, 2016Assignee: AKTIEBOLAGET SKFInventors: Alain Noordover, Sebastien David, Frank Fiddelaers, Albert van den Kommer
