Abstract: A dispensing apparatus provides for the dispensing of product from a collapsible tube. The apparatus includes a body for supporting the tube. The body has a forward end for accommodating a dispensing end of the tube and rearward end for accommodating a closed end of the tube. An elongate actuatable plunger is supported by the body. The plunger includes an elongate rod and a base attached to the rod. Actuating means is provided for effecting movement of the plunger in a first direction along the body for engagement with the collapsible tube wall thereby deforming the tube wall and dispensing the contents of the tube from the dispensing end. The actuating means also provides for retractable movement of the plunger in the second direction opposite the first direction. The base is positioned on the rod for dispensing engagement with the tube upon movement of the plunger in the first direction and movable out of dispensing engagement with the tube upon in a second direction.
Abstract: This invention relates to syntheses for the preparation of benzoxazine, including benzoxazine monomers and benzoxazime oligomers, from phenolic compounds, aldehyde compounds, and either primary diamine compounds, such as diamino alkylene compounds, e.g., methylene diamine, or diamino arylene compounds, e.g., phenylene diamine, using water, and optionally an organic solvent, as the reaction solvent.
Abstract: The present disclosure provides a cyanoacrylate-based composition comprising a cyanoacrylate component and an organic micropulp component dispersed in a curable (meth)acrylic monomer matrix. The composition is particularly useful as an adhesive composition for zero gap applications.

Abstract: A photo-curable resin composition for the UV-LED light source, which is rapidly cured and particularly has excellent surface curing property, is disclosed. The resin composition contains (a) polybutadiene (meth)acrylate; (b) a polythiol compound; and (c) a photo radical initiator and is photo-curable by an irradiation with an ultraviolet light-LED. Accordingly, production efficiency can be significantly increased in the production of liquid crystal displays and electrical and electronic components.
Abstract: A curing agent for epoxy resin has one or more five- or six-membered aromatic rings, and substituted on the one or more five- or six-membered rings at least two functionalities reactive with the epoxy selected from the group consisting of hydroxyl, amine, imidazole, azine, hydrazide, anhydride, and Lewis acid groups. Choice of functionality can provide a mixed polymer network, one with a more densely cross-linked polymer structure having a high Tg, and the other with a more linear polymer structure to contribute to stress reduction.
Abstract: Solvent free, moisture curable reactive hot melt adhesives are prepared using an oxazolidine functional prepolymer and a polyfunctional isocyanate.
Abstract: This invention relates to ruthenium initiators for the ring-opening metathesis polymerization (ROMP) of cyclic olefins that are inactive at room temperature but activatable at elevated temperature (referred to as (“thermally switchable”). In general, these are compounds of ruthenium metal to which are bonded four or five ligands, in which one ligand is a pyridine ring in which the nitrogen is chelated to the ruthenium, or a five or six membered ring incorporating nitrogen and the ruthenium in which the nitrogen is chelated to the ruthenium.
Abstract: The present invention relates to a method of fabricating a semiconductor package or circuit assembly using an fluxing underfill composition applied to solder contact points in a dip process.

Abstract: A fuel cell, having improved sealing against leakage, includes a sealant disposed over the peripheral portions a membrane electrode assembly such that the cured sealant penetrates a gas diffusion layer of the membrane electrode assembly. The sealant is applied through liquid injection molding techniques to form cured sealant composition at the peripheral potions of the membrane electrode assembly. The sealant may be thermally cured at low temperatures, for example 130° C. or less, or may be cured at room temperature through the application of actinic radiation.
