Appl. No.:

10/253942

Inventors:

Syed M. Hasan - Huntington Beach CA 92646

International Classification:

C09D 500

US Classification:

106 111, 1062872, 156314, 134 42, 427532, 216 18, 428421, 428422, 428901

Abstract:

A method and solution to activate and metallize the surface of a fluorocarbon material, suitable for circuit boards is disclosed. The surface of fluorocarbon materials is both hydrophobic and oleophobic, and highly inert and repellent to oils, dyes, adhesive and coatings. The method of the present invention makes such fluorocarbon materials wettable with metallizing solutions and chemicals, and also bondable with adhesives and coatings. The method comprises contacting said fluorocarbon surface with a mixture comprising a cyclic amide, a quaternary ammonium compound, a cationic or nonionic surfactant, a glycolether and an organic acid.

US Classification:

521 485, 521 48, 523501, 523523, 524605, 524845

Abstract:

The overall performance of water-reducible polymer dispersions, more specifically alkyd dispersions, can be substantially improved by utilizing resins derived from acidolysis reaction products of polyalkylene terephthalates and polyalkylene naphthalates. According to this invention, polymer dispersions can be produced from low acid value polymers and yet have good water dispersibility. When an aqueous coating composition is formulated using the dispersion of this invention, a final coating is formed that has good hydrolytic stability, and when blended with a latex, exhibits improved gloss and wet adhesion.

Inventors:

Syed Q. Hasan - Sugar Land TX, US

Assignee:

Rig-A-Lite Partnership Ltd. - Houston TX

International Classification:

G09F 13/00

US Classification:

40553, 40570, 40541, 40546

Abstract:

An exit sign for use in hazardous atmospheres including an explosion-proof housing and a sign panel with indicia thereon. The housing prevents the ignition of gas or vapor surrounding the enclosure due to sparks, flashes or an explosion of the gas or vapor within the enclosure by providing an ample heat sink surface along any flame path to cool gases escaping from the housing. The sign panel preferably includes one or more transparent sheets which are edge lit from a light source contained in the explosion-proof housing that shines through a window in the housing into the top edge of the sign panel to illuminate the face(s) and the indicia thereon. The light source utilizes a number of long life light emitting diodes. The exit sign preferably includes a sealed maintenance-fee rechargeable battery for powering the light source when externally supplied power to the exit sign is absent.
