Abstract
Abstract A composition for trapping and removing paint from a paint spray booth characterized by an aqueous solution-suspension containing at least 4 percent by weight of a water softener, a concentration within the range of 4-25 percent by weight of a colloid that will pick up moisture and swell and remain stable in highly alkaline solutions; a concentration within the range of 1-8 percent by weight of a surfactant; and a concentration within the range of 5-50 percent by weight of an alkaline material that is either an alkali metal hydroxyide or an alkali metal metasilicate. The composition preferably also includes a concentration within the range of 0.1-3 percent by volume of a defoamer. Specific and critical examples of the respective water softener, colloid, surfactant and defoamer are disclosed, as is the optimum concentration of the ingredients. Also disclosed are improved embodiments having additional additives incorporated thereinto for specific purposes with specific types of paints.
