Abstract: In accordance with the present invention, there are provided novel benzoxazine compounds and thermosetting resin compositions prepared therefrom. Invention compositions are particularly useful for increasing adhesion at interfaces within microelectronic packages. Invention benzoxazines are useful for the preparation of invention compositions with properties which are associated with increased adhesion at interfaces, such as, for example, low shrinkage on cure and low coefficient of thermal expansion (CTE). In another aspect of the invention, there are provided die-attach pastes having increased interfacial adhesion. Invention die-attach pastes include benzoxazine-containing thermosetting resin compositions. In further aspects of the invention, there are provided methods for enhancing adhesive strength of thermosetting resin compositions and methods for enhancing adhesion of a substrate bound to a metallic surface by a thermosetting resin composition.

Abstract: An apparatus (1) for the application of a composition curable by irradiation to a fastener (2) having a conveyor (3) for conveying fasteners to an application station (5); an application station (10) comprising an applicator from which the composition is dispensed. The conveyor rotates the fasteners past the applicator for application of composition. The same or another conveyor (8) conveys the fasteners to an irradiation station (10) and rotates the fasteners for irradiation thereof. The irradiation station irradiates and thus cures the composition applied to each fastener.

Abstract: A curable composition and method for producing a tear resistant, yet soft and deformable in-the-ear product yielding the user greater comfort and durability. The curable composition incorporated into a hearing aid apparatus provides a deformable, yet tear resistant housing, which may be mated to a soft tip component. The hearing aid housing provides better comfort, durability and acoustic performance for a variety of ear canal shapes. The curable composition that provides these properties includes at least one urethane acrylate oligomer, at least one reactive diluent and a cure system. The composition when cured desirably produces a tear strength of at least about 75 pli and a hardness of about Shore A 60 to about 75.

Abstract: A molding compound for use in encapsulating electronic packages which include an optoelectronic component, such as an LED or optical sensor. The molding compound includes a partially-cured epoxy composition, a linear polyol, a dye that absorbs in the region of above 700 nm to about 1200 nm and substantially transmits light from about 400 nm to about 700 nm, and an optional antioxidant material substantially uniformly distributed throughout the epoxy composition. The dye can be dissolved within the epoxy composition by heating a portion of the epoxy composition prior to B-staging of the molding compound. The cured epoxy composition has at least 40% transmittance at 600 nm, less than 10% transmittance at 900 nm, less than 10% transmittance at 1100 nm.
Abstract: A room temperature curable water-based semi-permanent mold release agent is provided that is effective to facilitate the release of multiple successively molded polymer (such as polyester) parts following a single application of the mold release agent to the mold surface. The mold release agent preferably is effective to set within 1 hour of application to a mold release surface at 5-40° C., and to cure at the same temperature within 1-8 hours of application. The mold release agent is substantially devoid of VOCs, and therefore has no flash point.
