Inflatable balloons with anti-blooming and anti-fogging coatings

摘要

A composition, method and apparatus for preserving the glossy, smooth exterior finish of a latex balloon wherein the exterior surface of the balloon is coated with an anionic aliphatic dispersion of polyester urethane material and dried. Coating can be accomplished by several methods including dipping in a bath. The coating can be applied either when the balloon is not inflated or inflated. The coating significantly increases the lifetime of the balloon without significantly decreasing buoyancy.
