Abstract: Disclosed is a sealing compound for can ends excellent in the adaptability to the lining operation, which comprises an aqueous latex of a styrene-butadiene rubber, a tackifier and a filler, wherein said latex contains styrene-butadiene rubber particles having a number average particle size of from 1600 to 3000 A, which are stabilized by an emulsifier or a dispersant.

Abstract: Disclosed is a metal bottle adhesive for lap-bonding upper and lower members, each consisting of a cup-like formed article of a metal, on the peripheral ends thereof, said adhesive comprising at least one high-molecular-weight thermoplastic resin having a post crystallinity .DELTA.Wc, defined by the following formula, of less than 20%:.DELTA.Wc=Wc.sub.II -Wc.sub.Iwherein Wc.sub.I stands for the crystallinity (%) of the adhesive which has been molten at a temperature higher by 30.degree. than the softening point thereof and then naturally cooled at room temperature, determined according to the density method, and Wc.sub.II stands for the crystallinity of the adhesive which has then been immersed in water maintained at 70.degree. C. for 10 hours and then naturally cooled and dried at room temperature, determined according to the density method,a shear creep compliance J(t).sub.t=2 hrs of less than 10.sup.-4 cm.sup.2 /hyne at 90.degree. C.

Abstract: A hydrophilic polymer shaped article adapted for use as a soft contact lens is treated to provide at least on the surfaces thereof a modified, less hydrophilic polymeric structure inhibiting penetration by proteins and other substances in the eye environment, whereby development of clouding and discoloration of the lens material during use is significantly retarded.

Abstract: Glass beads having a particle size of 1 to 200 microns are included as part or all of the filler in a sealing composition suitable for sealing container ends and which is made by dispersing a filler in a latex of a styrene butadiene or other rubbery polymer, optionally also containing a tackifying resin.

Abstract: Disclosed are heat-resistant adhesive compositions comprising a copolyester derived from terephthalic acid, from about 30 to about 50 mol % diethylene glycol, and at least 50 mol % ethylene glycol, the polyester having an inherent viscosity of from about 0.4 to about 1.0. The composition is especially useful in bonding parts of ovenable food containers.

Abstract: Water-borne epoxy-phenolic container coating compositions comprising a blend of(1) a water-miscible amine solubilized epoxy resin and(2) a water soluble monomeric phenolic compound.The coatings are especially useful, when cured, as container coatings and exhibit superior resistance to high acid and high protein foods.

Abstract: A non-toxic liquid stabilizer comprising, (a) from about 5 to about 35 percent of zinc resinate, (b) from about 5 to about 35 percent of calcium resinate, (c) from about 10 to about 40 percent of non-toxic plasticizer, (d) from about 1 to about 10 percent of a non-toxic antioxidant, and (e) from about 25 to about 75 percent of a non-toxic phosphite, said stabilizer containing from about 0.1 to about 3.5 percent zinc, and from about 0.025 to about 2.28 percent calcium, all weights being based upon the total weight of the stabilizer, is disclosed. Also disclosed is a similar stabilizer which does not contain phosphite and contains from about 25 to about 90 percent of the plasticizer. A method for stabilizing halogenated hydrocarbon resins utilizing the stabilizers of the present invention is also disclosed.

Abstract: A place mat is disclosed which comprises a paper sheet and a composition coating comprising a blend of water, a water soluable salt, a wax and a polymeric material which both coats and impregnates the paper sheet, whereby said sheet is rendered substantially hydrophobic and it and items placed on it are rendered substantially slip resistant when resting on a tray or table which may be subject to sudden movement. The non-slip place mat is particularly useful for airline serving trays.

Abstract: Disclosed is a paint for a can which comprises an epoxy resin component formed by condensation of a dihydroxyl compound with an epihalohydrin and a curing agent component, said epoxy resin component containing terminal .alpha.-glycol groups at a concentration of 0.05 to 0.60 equivalent per Kg of the resin.This paint provides a coating capable of retaining a high adhesion even with the lapse of time and resisting a severe treatment such as retort sterilization.When this paint is applied to a bonded can, leakage of the content from the side seam with the lapse of time can be effectively prevented. When this paint is applied to a can provided with an easy-open can lid, occurrence of the enamel feather can be prevented at the time of opening the lid.
