20080216954 | Plastic Welding Compound - The invention is a combination of a Methyl Methacrylate liquid monomer and an acrylic powdered polymer that when mixed together will form an extremely strong chemical bond between two plastic substrates by melting into the plastic and filling the space between the substrates. A bond stronger than previously achievable is accomplished by two factors: (1) Substantial use of the liquid as a primer before the application of the mixture in order to prepare the surface for welding. (2) Controlling the temperature of the liquid and the powder, via refrigeration, before mixing. This allows workability of the product without the need for additives that dilute the strength of the mixture. The elimination of the additives also allows for a more pure weld that can be polished to a crystal clear surface for an esthetically pleasing joint. | 09-11-2008 |
20080264561 | Method for Thermal Seaming of Polyimides - The present invention is a method for seaming a polumide material. The method involves forming an interface between multiple the polymide materials. Next, heat is applied to the interface to soften the polymide material. The temperature of the heat source is below the melting point of the polyimide material. Finally, pressure is applied to the interface to create a seam between the poluimide materials. | 10-30-2008 |
