AKTIFIT Q is an activated SILFIT Z 91, produced by modifying the surface with a methacrylic 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, which are potentially encountered with in-situ mixing (direct addition of additive to the compound).
A special process technology during the production of AKTIFIT Q provides high hydrophobicity as well as outstanding low moisture absorption even under very humid conditions. During curing (hardening) of the coating, the methacrylic groups of AKTIFIT Q react with the functional groups
of the binder, especially in the presence of radicals.
