Abstract
A plastic repair composition of matter and process for making same. The repair composition comprises a major proportion of a first solvent selected from the group consisting of methyl ethyl ketone, methyl isobutyl ketone, acetone, cyclohexanone, isophorone, ethyl acetate, butyl acetate, xylol, toluene, toluol, amyl acetate, and mixtures thereof. The repair composition additionally includes a minor proportion of a mixture including a second solvent having the formula: wherein R1, R2, R3 and R4 are selected from the group consisting of hydrogen, alkyl hydrocarbons containing from between 1 to 6 carbon atoms, and mixtures thereof, a plasticizer selected from the group consisting of tricresyl phosphate, dioctyl phthalate, and mixtures thereof, a synthetic vinyl polymer resin product selected from the group consisting of vinyl chloride, vinyl acetate, polyvinyl chloride, polyvinyl acetate, and mixtures thereof, and dibutyl tin dilaurate having between about 17 and 20 percent weight tin.

Method of bonding and bonding compositions

TL;DR: In this paper, a method of adhesively bonding or welding a first plastic surface to a second plastic surface is described which comprises the steps of applying to the first surface or second surface or both surfaces, a composition which is free of hollow microspheres and comprises a mixture of (A) from about 5% to about 60% by weight of at least one water-insoluble polymer selected from ABS, PVC, CPVC or mixtures thereof; (B) from approximately 1% to approximately 60% in weight of one waterinsolerant polymers selected from acrylic

Method for repairing articles

TL;DR: In this article, a method for repairing cracked and broken plastic articles such as lenses for automobile signal lights and the like comprises the steps of placing a form against a first surface of the plastic article such that the form covers the broken area, preparing an adhesive sealing compound which cures by exothermic reaction, applying the compound to the damaged areas of the lens from an opposite surface of a lens, heat generated by the exthermic reaction causing decreased viscosity of the compound and widening of cracks in the lens, the compound flowing into the widened cracks before curing, and removing the form
