Filed:

Jan 5, 2001

Appl. No.:

09/755510

Inventors:

David William Garrett - Marietta GA

Assignee:

Cookson Singapore PTE Ltd.

International Classification:

C08K 310

US Classification:

523458, 523465, 523466, 525523, 528118, 528418

Abstract:

The invention is directed to novel epoxy molding compounds for the encapsulation of microchips in the electronics industry. Known epoxy molding encapsulants are generally prepared from a blend epoxy resins, phenol hardeners, silica fillers, catalysts, flame retardant materials, processing aids and colorants. The addition of polybenzoxazines as a co-reactant with one or several epoxy resins provides a product with reduced moisture adsorption while maintaining a high glass transition temperature.

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

C08G 1800

US Classification:

20415915

Abstract:

A low dosage radiation polymerizable protective and decorative coating composition or paint, coated articles bearing such a protective coating and processess for preparing such articles. The radiation polymerizable coating composition comprises an organic resin/monomer mixture of: (A) between about 97 and about 3 weight percent alpha-beta olefinically unsaturated organic resin containing between about 0. 5 and about 5 vinyl unsaturation units per 1000 molecular weight of said resin, and (B) between about 3 and about 97 weight percent vinyl monomers polymerizable with said resin upon exposure to radiation, characterized in that said vinyl monomers include N-vinyl-2-pyrrolidone in an amount of from about 3 and up to about 10 weight percent based on the total weight of (A) and (B). The flexible coating exhibits excellent physical qualtities and good adhesion to a variety of substrates being particularly suitable for use on vinyl chloride fabric, wherein it is discoloration resistant after heat aging. Preferred articles bearing such a coating, which may comprise large amounts of pigment, are preferably cured by exposure to electron beam radiation.

Assignee:

Owens-Corning Fiberglas Corporation - Toledo OH

International Classification:

C08K 515

US Classification:

524114

Abstract:

Aqueous size compositions for glass fibers including melamine formaldehyde resins, phenoxy resins and epoxy coupling agents which are particularly suitable glass fiber reinforcements for thermoplastics. In particular, chopped glass fibers coated with the size are useful in reinforcing acetal composites.

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

C08G 5916

US Classification:

525528

Abstract:

Free-radical curable amino vinyl ester resin binder compositions for fiber reinforced composite materials with improved interlaminar shear strength and accelerated cure rate. The composition comprises about 80 to about 20 weight percent of amino vinyl prepolymer and about 20 to about 80 weight percent of a crosslinkable diluent, wherein the prepolymer consists essentially of the reaction product of epoxy-amino alcohol adduct and unsaturated monomer having a terminal vinyl group and a hydroxy reactive functionality capable of reacting with the hydroxyl groups of the adduct. The polyepoxide and amino alcohol, preferably a diethanol amine, are reacted in a ratio of about 1:1-1. 2 equivalents of epoxide to amine groups, so as to react essentially all of the epoxide groups. Subsequently, between about 0. 3-1. 0 of the hydroxyl groups of the adduct are reacted with the vinyl monomer.
