AKTISIL Q is based on a specially designed and activated SILLITIN V 90* whose surface has been modified with a methacryl functional group. The by-products split off during the treatment reaction are largely removed during the production process which firmly attaches the functional
group to the filler surface. This helps minimize undesirable side effects, as they are potentially encountered with in-situ mixing (direct addition of additive to the compound).
During vulcanization the methacryl groups of the AKTISIL Q react with the polymer in the presence of radicals.
