The present invention provides an anti-corrosion composition comprising an organic ion-exchanger; and a solventborne resin, wherein a substrate exposed to a halide-containing environment and having the anti-corrosion composition applied thereto has a reduced level of corrosion compared to the substrate exposed to the halide-containing environment without the anti-corrosion composition being applied. The inventive solventborne anti-corrosion composition may find use on substrates such as automotive vehicles, bridges, cranes, superstructures, offshore oil & gas rigs, pipes, tanks, ships, barges, boats, aircraft, concrete, and masonry that are exposed to halide-containing environments.

A method of encapsulating content with calcium alginate membrane to form a capsule. The method includes embedding sodium alginate into a traditional gelatin ribbon used in gelatin encapsulation, adding calcium to a fill material, encapsulating the fill material, and then denaturing the gelatin in the shell. An exemplary use of this method is to form throwable paintballs; however, other products could be formed using this process. A paintball formed by this process is also disclosed.
