Abstract: This disclosure relates to a method for the in-situ encapsulation and/or insulation of piping using silicone-based compositions such as liquid silicone rubber materials and/or silicone foams. The method is useful for encapsulation and/or insulation of underground piping, particularly underground piping carrying high temperature (e.g., >120° C.) fluids, such as steam. The in-situ encapsulation and/or insulation may be done by inserting a hose into a pipe cavity so that a first end of the hose is remotely positioned next to the pipe and a second end of the hose is attached to a pumping system. A silicone composition is pumped through the hose and into the cavity surrounding from the remote first end of the tubing at a first predefined rate, and the hose is gradually withdrawn from the cavity at a second predefined rate. The silicone material is allowed to cure and become rigid, thereby encapsulating and/or insulating the pipe.

Abstract: The present invention provides bi-component core-shell polymeric microfibers for reinforcing concrete comprising as a first component (shell) ethylene-vinyl alcohol (EVOH) polymer and at least one plasticizer, preferably, polyethylene glycol, and as a second component (core) a polymer chosen from a polyamide, a polyester, such as polyethylene terephthalate, and a polymer blend of a polyolefin and an anhydride grafted polyolefin and having an aspect ratio of length to diameter (L/D) or equivalent diameter of from 300 to 1000. The bi-component polymeric microfibers comprise from 5 to 45 wt. % of the first component, are easily processed, and provide fiber cements having improved mechanical properties at relatively low microfiber loadings.

Abstract: An epoxy resin composition having a first epoxy resin component containing an oxazolidone; a second epoxy resin component; a latent hardener comprising dicyandiamide particles having a particle distribution in which at least 35% of the dicyandiamide particles have a particle size of less than 2 microns; and an epoxy soluble latent catalyst is provided. It has been found that the combination of the epoxy components, a latent hardener having dicyandiamide particles in which at least 35% of the dicyandiamide particles have a particle size of less than 2 microns, and an epoxy soluble latent catalyst provides an epoxy resin composition that provides a more homogeneous infusion of the resin into a fibrous material for forming a prepreg. As a result, faster cure of the epoxy resin composition is obtained, which in turn, reduces the mold cycle time for preparing molded articles and parts.
