Abstract: A one component epoxy adhesive composition is comprised of an epoxy resin, a polyurethane based toughener, an epoxy capped toughener comprised of a polymer backbone capped with an epoxy, wherein the polymer backbone is at least partially immiscible in the epoxy resin; and an epoxy curing agent. The one component adhesive composition may have improved impact resistance at low temperatures, such as ?40° C. or less. The epoxy based toughener may be formed by reacting the hydroxyls of a polyol with a stoichiometric excess of cyclic anhydride to form a carboxylic acid capped polymer. The carboxylic acid capped polymer is then reacted with a stoichiometric excess of an epoxy resin having at least two epoxides to form the epoxy capped toughener having epoxide end groups.

Abstract: The present invention relates to a process to reduce internal stresses in insulation molded onto complex pipes, preferably complex subsea pipe, to reduce cracking in the molded insulation. Insulation materials applies to complex pipes comprising branches, i.e., valves, and the like, may be susceptible to cracking at, or near where the branch connects to the pipe as the coating of insulation material cures or hardens. The process of the present invention aims to reduce post molded cracking by reducing molded in stress at the branch/pipe junction. This is accomplished by providing a preform at or near a branch/pipe junction prior to applying the coating of insulation material.
