CERTAIN RADIATION CURABLE FORMULATIONS can develop foaming problems during the manufacturing process, and in certain instances, this foam will build up and become a difficulty. In other cases, the foam may only appear at particular times or with particular formulations. In either case, foam can be, at best, a nuisance and, at worst, can cause major losses in production. These additives, which usually are silicone fluids, modified silicones, or acrylics, can be obtained from several suppliers, and only a couple will be mentioned. The silicone fluids are different molecular weight dimethylpolysiloxanes, and the modified silicone compounds are variations of this structure, in which some or all of the methyl groups have been replaced with other groups.
