Abstract: Embodiments of the invention provide an apparatus or process for devolatilization of flowable materials (such as molten polymers with entrained or dissolved solvent or unreacted monomers or comonomers) using a plate heater having heating channels, the design or operation of which heating channels maintains the flowable material above its bubble point pressure during passage through a larger first zone and then induces flashing in, or downstream of, a smaller second zone of the heating channel. The apparatus enables a higher throughput per heating channel while achieving equivalent or better devolatilization, as compared to current devolatilization apparatus.

Abstract: The present invention relates to an aqueous epoxy resin blend dispersion of a high mw epoxy resin and a liquid epoxy resin with a dispersant having an interfacial tension such that a drop of the mixture of the dispersant in a melt of the epoxy resin blend against water is less than 2 dynes/cm, preferably less than 1 dyne/cm, and a process for preparing this epoxy resin blend dispersion. Specifically, the process is a solvent free melt kneading or shearing dispersion process wherein the dispersion is processed at from 50 to 150° C., and the resulting dispersion is stable.
Abstract: An epoxy adhesive composition is provided that has superior wash-off resistance after pre-gelling, and may be used, e.g., in manufacturing processes, e.g., in the automobile industry. The compositions comprise an epoxy resin, a gelling agent, and a phenolic agent, and may optionally comprise other components. Methods of making and using the compositions are also provided.
Abstract: A heat-curable structural adhesive includes at least one non-rubber-modified epoxy resin; an optional rubber or toughener, one or more epoxy curing agents, one or more epoxy curing catalysts; and a flame retardant mixture that includes (i) alumina trihydrate, (ii) zinc borate and (iii) melamine or a melamine derivative. The structural adhesive is useful for bonding metals to other materials or metals to other metals. The structural adhesive strongly resists ignition when welding is performed in the presence of the uncured material, and does not interfere significantly with weld performance.
