    Abstract: 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-1,2-diphenylethan-1-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. Preferably the use of cobalt is avoided altogether. The use of the low concentrations of the other metal ions reduces discoloration of the compositions often to levels below what is achieved using conventional cobalt promoters.

  • Publication number: 20040116547
    Abstract: The present invention relates to dual curing silicone compositions which are capable of crosslinking when subjected to actinic radiation and/or heat. The compositions contain a reactive organopolysiloxane having a function group selected from the group consisting of (meth)acrylate, carboxylate, maleate, cinnamate and combinations thereof; a silicon hydride crosslinker; an organo-metallic hydrosilation catalyst; and a photoinitiator. These compositions can be cured to relatively thick films using UV light due to the presence of the specific olefinic unsaturated groups, and can also be partially or fully cured at room temperature or under thermal exposure. These compositions are particularly useful as conformal coatings, and in particular as coatings in electronic applications.
