A composition and method and apparatus for increasing the buoyant lifetime of a gas inflatable elastomeric balloon wherein a surface of a balloon is coated with an aqueous solution containing 3 to 50 percent polyvinyl alcohol, and up to 20 percent of a water soluble plasticizer for polyvinyl alcohol such as glycerine, which coating is dried while the balloon is in the inflated condition. Treatment of a rubber latex balloon having an inflated diameter of about 15 cm to about 50 cm by the method of this invention can increase its buoyant lifetime about 600...
A method of coating an inflatable elastomeric toy balloon having an inflated diameter of from about 15 cm to about 50 cm with a diffusion barrier film to increase the floating lifetime of the balloon when in an inflated condition, comprising the steps of: applying a liquid comprising an aqueous solution of a dispersed gas diffusion barrier coating material to a surface of the balloon; expanding the coated surface by inflating the balloon; and drying the liquid while the balloon is in an inflated condition with said surface expanded. An inflatable balloon...
