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.

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.

International Classification:

C25D 544

US Classification:

204 33

Abstract:

Metals and alloys of metals which have the property of electrolytic rectification can be coated with an anticorrosive coating by immersion in a strongly alkaline aqueous bath comprising a water soluble fluoride, a water soluble iron salt, and mixtures thereof by the application of a sufficiently high voltage to obtain spark discharge at the surface to be coated, said potential being applied between the metal or alloy to be coated utilized as an anode and a cathode immersed in the aqueous bath. A durable coating is thereby applied to the surface of said metals or alloys thereof which is resistant to a corrosive salt spray environment.

International Classification:

B60K 4106
B60K 4128
F02P 515

US Classification:

477 91

Abstract:

An ignition timing control method for a vehicle which provides an engine torque output waveform for canceling vibrational disturbances caused by sudden throttle plate movement resulting in engine accelerations and decelerations. The ignition timing is variably advanced and retarded in accordance with a phase-shifted derivative of engine speed to produce an appropriate engine torque output waveform for optimally canceling the vehicle vibrational disturbances. The phase shift is accomplished by applying a time delay to the engine speed derivative. A negative bias is added to the ignition timing for retarding ignition timing by a predetermined amount to permit a full sinusoidal canceling waveform. A blend multiplier is utilized to gradually remove the effects of the canceling waveform and bias, thereby gradually returning the ignition timing to its original setting.
