Abstract: Relatively non-toxic and environmentally safe paint stripping compositions are disclosed for use in removing, for example, oil based alkyd and latex paints, varnishes, lacquers, shellacs, enamels, polyurethane and epoxy coatings from wood and metal surfaces at ambient temperatures. It has been unexpectedly found that C.sub.3 -C.sub.7 ether esters and carbonates of the form R--O--(CH.sub.2).sub.n --COOR.sub.1, wherein R and R.sub.1 are lower alkyl groups and n=0-2, used in combination with tetrahydrofurfuryl alcohol (THFA) increase the rate of paint removal relative to THFA alone. Other ingredients, such as N-methyl-2-pyrrolidone (NMP), gamma-butyrolactone (BLAC) may be added to improve the efficacy of the present invention without detracting from its other beneficial properties. Additives such as formic acid, surfactant, thickener, corrosion inhibitor, fragrance, and bittering agent may also be added.

Abstract: Hot melt construction adhesives are described which possess superior properties for the construction of disposable soft articles. The adhesive compositions include an SIS copolymer containing at least about 25% styrene, a compatible tackifying resin, a plasticizing oil and an effective amount of a stabilizer.

Abstract: Foundary binder, substantially free of inert hydrocarbon solvents, is comprised of a mixture of low molecular weight methylolated phenolic components and a reactive diluent. The binder is mixed with sand and cured with a polyisocyanate in the presence of a catalyst.
