BARRETT PHTHALIC ANHYDRIDE American housewives recognize degrees of 'whiteness. They demand that white household equipment be a pure gleaming white—without any trace of color—and they expect it to stay that way indefinitely.
Such finishes require products of established purity . . . Barrett phthalic anhydride, for instance.
Barrett phthalic anhydride in the solid state has a pure flat white color with no tints of any primary color. This color is retained indefinitely; tests of samples in storage for several months show no change.
In the molten state, Barrett phthalic anhydride is practically water-white or colorless and tests well within the limit of the standard specification of 55-Hazen established by the industry. In actual tests, it has remained within the limit of 55-Hazen when kept molten for more than 60 hours—a period of time well beyond any normal requirement for processing in plant kettles.
These qualities of Barrett phthalic anhydride make its use especially desirable in better alkyd coatings where whiter finishes and perfect colors are required.
It is shipped in 5-ply paper bags, even net weight 80 lbs., and in light wooden barrels, even net weight 275 lbs.
