123518, 123516

Abstract:

A vapor removal fuel containment fuel tank for a vehicle includes a tank shell having a wall formed from a primary fuel containment layer. The fuel tank also includes a secondary fuel containment layer disposed adjacent the primary fuel containment layer to contain fuel therein. The fuel tank further includes a vapor removal system extending through the primary fuel containment layer to allow fuel vapors that build up between the primary fuel containment layer and secondary fuel containment layer to be removed from the fuel tank.

B32B 2740

US Classification:

428174

Abstract:

A method of applying a prepainted carrier film to an automobile body part in a vacuum thermoforming process. The prepainted carrier film has a top surface painted by a color coat formulation not containing any flakes and then coated with a layer of clear coat having a thickness of no less than 10 microns. The prepainted carrier film is heated and stretched in a vacuum thermoforming process and then assembled to a substrate for an automobile body part by adhesive means. The clear coat layer retains substantially the same gloss and color appearance of the stretched prepainted carrier film as prior to the such stretch.

International Classification:

B01J 1302

US Classification:

264 4

Abstract:

In accordance with a preferred embodiment of this invention, an active agent, such as a catalyst or a cocatalyst, is encapsulated in a dual-walled microcapsule. Both walls of the microcapsule are polymerization reaction products and both are formed in one basic process. The active agent is initially dissolved in a slowly polymerizing liquid monomer mixture such as a solution of toluene diisocyanate and a polyoxyalkylene polyol. The "monomer solvent" and the active agent combination is selected so that the active agent is nonreactive but soluble in the liquid monomer and insoluble in the polymer formed therefrom. However, before the active agent precipitates, the solution is dispersed in a nonreactive medium and the outer polymeric wall is formed by vigorously stirring the dispersion and then adding a reactive polyfunctional monomer. This polyfunctional monomer, which preferably has two primary aliphatic amine functionalities in terminal or near terminal positions, such as ethylene diamine, quickly reacts with the isocyanate of the initial monomer solution, via an interfacial polymerization reaction, to form the outer polyurea wall around each bead in the dispersion. Then the active hydrogen functionalities of the urea groups on the inner surface of the outer wall react with a portion of the nonreacted isocyanate functionality to form a biuret linkage between the outer wall and either or both the polymerizing monomer solution and the inner polymer wall which is formed therefrom.

International Classification:

Abstract:

Urethane-urea flow control agents are synthesized by a two-step process. First, an isocyanate-terminated urethane prepolymer is prepared by reacting a polyether polyol with a stoichiometric excess of a saturated cyclic aliphatic polyisocyanate. These isocyanate-terminated prepolymers are then modified by reaction with an ethanolamine to form urea endcapped flow control agents having number average molecular weight of between 1000 and 4000. These urea endcapped flow control agents can be blended with any urethane paint system and be compatible in structure. They have shown specifically superior compatibility with melamine cured high solids urethane paint systems. When blended with pigmented urethane paint at relatively small amounts, these flow control agents greatly reduce sagging while maintaining excellent leveling and viscosity properties of the paint.
