Title Letterflex photoprepolymer sensitization in newspaper printers due to pentaerythritol tetrakis(3-mercaptopropionate) and 3-mercaptopropionic acid.
Bibliographic information Oct. 1977, Vol.3, No.5, p.257-262. Illus. 8 ref.
Abstract The Letterflex urethane photoprepolymer mixture contains 8 components. The substances mentioned in the title gave positive reactions in 5 patients with contact allergic dermatitis. Two systems (one semi-, one fully automatic) used are described; precautions in the handling of these chemicals are recommended, above all with reference to the soiling of the back of the carrier plate, even of the fully automatic system, by the uncured mixture, which then spreads to workers' hands.
