Abstract: An improved polyurethane RIM process using a polycarboxy-functional alkyl siloxane as an internal release agent characterized by:(1) Tool break-in or preconditioning with siloxane treatment of the surfaces;(2) Supplying the siloxane to the mix head as a third stream when necessary to prevent undesired side reactions;(3) Using a minimal amount of siloxane that is inadequate for mold release in the absence of the tool preconditioning;(4) Adjustment of catalyst package to counter the inhibiting effects of the siloxane.The use of a bare minimal amount of siloxane prevents excess siloxane from appearing in the surface of the article and causing subsequent paint wet-out and like difficulties. The third stream isolating of the siloxane prevents its carboxy-functional groups from reacting with the prepolymer or with other ingredients that may be carried in the polyol blend.

Abstract: An improved breather system for a sealed storage structure. An annular flexible diaphragm is located within the upper portion of the storage structure and the inner periphery of the diaphragm is sealed to a central inlet feed tube, while the outer periphery is sealed to an impervious platform that is mounted on the wall of the structure beneath the roof. A manhole is provided in the roof for entry onto the platform by workmen in order to repair or replace the diaphragm. The diaphragm and platform separate the storage structure into a lower storage chamber and an upper chamber which is exposed to the atmosphere. The diaphragm will move up and down within the structure in accordance with the pressure differential between the chambers. The diaphragm has a substantially greater surface area than the cross section area of the storage structure, so there is substantial travel between its uppermost and lowermost positions to thereby greatly increase the breathing capacity over conventional breather systems.
