AUTOXIDISABLE ARCHITECTURAL COATING COMPOSITIONS

摘要

An autoxidisable architectural coating composition suitable for application to surfaces found in and around buildings at ambient temperatures and in natural daylight wherein surface autoxidation of the composition is promoted by a combination of low concentrations of metal ions (especially manganese or vanadium) and 2, 2-dimethoxy-l , 2-diphenylethan-l-one as photoinitiator. The composition avoids the need to use more than trace amounts cobalt ions which are rumoured to be carcinogenic yet achieves adequately fast rates of autoxidation.
