  • Cleaning solutions for removing uncured polyester resin systems from the surfaces of processing equipment
    Patent number: 5378386
    Abstract: Uncured polyester resins are removed from the surfaces of processing equipment, e.g. mixing and injection heads, by a cleaning solution comprising:A. At least about 50 weight percent of at least one dibasic acid ester, such as DBE;B. A sufficient amount of at least one free radical polymerization inhibitor, e.g. hydroquinone, to inhibit the cure of the polyester resin system; andC. A sufficient amount of at least one chelating agent, e.g. tartaric acid, to inhibit the promotional effects of the metal-ion promoter of the free radical polymerization catalyst system.
