Title Slow curing of aliphatic polyisocyanate paints in automotive refinishing: A potential source for skin exposure
Bibliographic information June 2007, Vol.4, No.6, p.406-411. Illus. 26 ref.
Abstract Polyurethane paints containing aliphatic isocyanates used in automobile body spray painting can cause asthma, and skin exposure may be an important route of sensitization. Automobile body workers are frequently in contact with recently painted and dried auto parts. It is not known how fast the newly-painted car surfaces are fully cured. To address this question, sections of auto bodies were painted and dried by automobile body shop painters following regular practice. It was found that unbound isocyanate species remained present on the majority of painted surfaces for up to 120 hours for typical paint formulations and for one month in some cases. Such surfaces are an under-recognized potential source of skin exposure to automobile body workers.
