Abstract: A high shear adhesive tape having an adhesive layer containing a rubber mix and at least one tackifier agent, the rubber mix including an effective amount of a crosslinked halogenated butyl rubber, the remaining rubber in the mix being non-crosslinked, the non-crosslinked rubber preferably being butyl rubber, the adhesive layer further being characterized as being free of any crosslinking agent for the remaining rubber in the mix; and pipewrap systems employing this tape.

Abstract: Disclosed is a novel system for providing transparent electrically conductive tin oxide coatings on substrates, which system includes the steps of doping a tin oxide colloid stabilized with ammonium ions with antimony, coating the resulting mixture onto the substrate to be provided with the electrically conductive coating, and then drying or baking for a time and at a temperature sufficient to lower the sheet resistance of the coating to the desired level.

Abstract: Disclosed are novel antimony oxide flame retardant dispersions containing trivalent antimony deposited on the surface of antimony pentoxide particles, which compositions are particularly useful for providing flame retardancy to fiberglass products.

Abstract: Disclosed are a novel class of colloidal antimony pentoxide powders having improved dispersibility in polar solvents; and novel processes for preparing same, which processes include the initial step of preparing a new intermediate consisting of an antimony pentoxide/phosphoric acid sol containing at least 35% by weight of antimony pentoxide based upon the total weight of the sol.

Abstract: Disclosed is a method for preparing aqueous negatively charged tin oxide sols having substantially uniform particle size no greater than about 50 nm and preferably from about 5 to about 20 nm, the sols being characterized as being substantially free of any other reagents which may adversely affect contemplated usage as a catalyst.

Abstract: Polymer systems can be rendered flame retardant by adding a source of halogen and particles of antimony pentoxide that have been dried from colloidal dispersions that have been treated with certain metal ions. The properties of the polymer are conserved when the colloidal dispersion is treated with ions of metals that have insoluble antimonates before drying to form a powder.
