The second distillation fraction provides a low odor composition of the dicyclopentenyl ester which is useful as a reactive coalescent.Type: GrantFiled: February 23, 2000Date of Patent: January 21, 2003Assignee: Rohm and Haas CompanyInventor: William David Weir

Patent number: 6475299Abstract: Disclosed are a conversion coating composition for use in the surface treatment of a PCB and a conversion coating method using the same. The composition comprises 0.1-30 vol % of sulfuric acid; 0.1-15 vol % of hydrogen peroxide; 0.01-10 wt % of an organic acid; 0.1-30 wt % of a nitrogen compound; 0.01-10 wt % of an organic silicate and/or organic titanate; and 0.1-20 wt % of a film forming auxiliary, 0.1-30 wt % of an etching rate controller, 0.1-20 wt % of a reaction promoter and/or 0.1-20 g/l of a stabilizer. This composition is applied to a PCB at 10-60° C. for 1-10 min. The conversion coating film is superb in adhesive strength, acid resistance, and adhesion and can be formed with ease.Type: GrantFiled: July 7, 2000Date of Patent: November 5, 2002Assignees: Samsung Electro-Mechanics Co., Ltd., SD Chemical Co., Ltd.Inventors: Byong Ho Lee, Dek Gin Yang, Yang Je Lee, Myong Gun Chong, Jae Ok Lim, Sung Wook Chun, Min Eui Hong, Kyu Hong An

Patent number: 6464763Abstract: A composition for use in forming a dry film coating on metal surfaces to at least temporarily protect the surfaces from oxidation comprises at least 20% by weight of a combination of at least one saturated linear carboxylic monoacid with at least one unsaturated linear carboxylic monoacid. The monoacids are in the form of alkaline, alkaline-earth or amine salts. The carbon chain of each acid comprises an uneven number of carbon atoms varying from 5 to 21. At least 0.5% by weight of a triazole derivative can be added to enhance the anti-corrosion effect. The composition is water-soluble and the dry protective film can be formed by diluting the composition in water, applying the diluted composition to a metal surface and then air drying it.Type: GrantFiled: May 22, 2001Date of Patent: October 15, 2002Assignee: Elf Antar FranceInventors: Pierre Steinmetz, Jacques Cotteret, Corinne Chauvineau
