A water-based bonding primer composition and a method of applying the same onto a metallic surface prior to adhesive bonding. The bonding primer composition is a water-based dispersion containing water, one or more epoxy resins, one or more curing agents, a silane compound, a low amount of propylene carbonate (PC), and optional additives. The bonding primer composition can form substantially smooth films by spraying, and at the same time, meet environmental regulations and provide high bonding performance.

The invention relates to a surfactant mixture having at least two different sulfosuccinates, and an additional surfactant selected from the group consisting of alkoxylated aliphatic alcohols, and to a method of treating a hydrocarbon oil containing formation by injection of solutions including mixtures of these surfactants.


Processes for enhancing filtration rate and/or clarification of phosphoric acid produced by the wet process and containing suspended insoluble particulates by adding to one or more stage of the wet process phosphoric acid production stream an effective amount of a reagent including polymeric microparticles characterized as being anionic or amphoteric and having a weight average molecular weight of greater than 60 Million daltons are provided herein.


A thermally expandable and electrically conductive material capable of providing lightning strike protection and burn-through resistance, containing electrically conductive fibers; thermally expandable particles; and a curable matrix resin comprising one or more thermoset resins, wherein the electrically conductive fibers and the thermally expandable particles are embedded in the curable matrix resin.


A resin-rich peel ply that does not leave behind residual fibers after peeling and can work well with different resin-based composite substrates. The resin-rich peel ply is composed of a woven fabric impregnated with a resin matrix different from the resin matrix of the composite substrate. The peel ply is designed such that, upon manual removal of the peel ply from the composite substrates surface, a thin film of the peel ply resin remains on the composite substrates surface to create a bondable surface capable of bonding with another composite substrate, but no fibrous material from the woven fabric remains on the same surface.

Disclosed herein is an epoxy resin compositions comprising an epoxy component and a curing agent component, wherein the curing agent component is at least an aminoalkylimidazole curing agent, and wherein the epoxy component and the curing agent component react together at a temperature of about 100 C. to about 130 C. to form a substantially cured reaction product in about 10 minutes or less. Further disclosed are composite products formed from such epoxy resin compositions.


The present invention relates to low or zero-tack composite materials such as pre-pregs and their use in automated manufacturing, particularly robotic pick and place. The present invention further relates to an automated process for preparing an article, particularly a moulded article, from a fibre-reinforced composition material. The moulded articles prepared by the process described herein are particularly suitable as components for transport applications, and particularly the automotive industry. The automotive components prepared by the present invention are particularly suitable as mid- or high-volume automotive parts, in which cost and speed of production are paramount. The present invention provides a process in which the cutting and handling of pre-preg materials is greatly simplified, providing advantages of efficiency and economy. The lay-up time according to the present invention is significantly reduced, allowing a reduction in the unit cost per component and/or allowing the high volume of component production desired in the automotive industry.
