Abstract: A curable adhesive that is particularly well suited for use in an injection or compression molding operation. The adhesive is based on polymeric resins having carboxylic acid and acrylate ester functionality, such as grafted phenoxy resin, and further constituents such as organic carbonates, blocked isocyanates, catalysts, maleimide compounds, hydride sources, and a carrier fluid. The curable adhesives are particularly well suited for bonding liquid injectable substrates such as liquid silicone rubber, or polyamides to rigid substrates, such as aluminum, stainless steel, or glass.

Abstract: A heat exchanger is provided including a first aluminum extruded header spaced apart and arranged essentially parallel to a second aluminum extruded header. The first and second headers include a plurality of parallel passageways extending therethrough along a longitudinal axis thereof. The passageways are fluidly interconnected by at least one transverse cross-drilled bore extending essentially perpendicularly to the longitudinal axis. A core assembly is secured between the first and second headers including a plurality of fluid conduits and heat radiating fins surrounding the fluid conduits. A by-pass valve assembly fluidly communicates with the headers and core assembly while providing an alternate pathway independent thereof. Preferably, the by-pass assembly is responsive to fluid temperature and/or pressure for directing fluid flow either into or exterior of the heat exchanger core assembly.
