Publication number: 20110017400Abstract: The invention is based on the discovery that addition of certain carboxylic acid derivatives of siloxanes to thermosetting adhesive compositions and die-attach pastes renders such compositions and pastes extremely resistant to resin bleed. The present invention provides siloxane-carboxylic acid compounds useful as anti-bleed additives. Also provided are adhesive compositions and pastes containing the compounds of the invention, which are particularly useful in applications that require little to no resin bleed prior to curing of the compositions (such as e.g., electronic packaging applications).Type: ApplicationFiled: March 23, 2009Publication date: January 27, 2011Applicant: DESIGNER MOLECULES, INC.Inventor: Stephen M.
