Aktifit® VM by Hoffmann Mineral acts as a functional filler. It is an activated Silfit® Z 91 produced by modifying the surface with a special vinyl functional group. It can be used either on its own or combined with extenders or matting agents. It is quick-drying, has a matting effect, and shows good scratch-, abrasion-, chemical-, water- & weathering resistance. Suitable for UV-cured- clear coats (varnishes) & powder coatings, pigmented-, wood- and film (UV/eximer curing) coatings. It is used in acrylic resins as well as unsaturated & peroxide-cured polyester & vinyl ester resins.<br>
<ul style="padding-left: 40px;"><li>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 and helps to minimize undesirable side effects.</li>
<li>Its special process technology provides high hydrophobicity and outstanding low moisture absorption even under very humid conditions.</li>
<li>During curing (hardening) of the coating, its vinyl groups react with the functional groups of the binder, especially in the presence of radicals.
<li>It enhances the opacity (spacer effect) of pigments and acts as a replacement potential of titanium dioxide of up to 20% or increasing hiding power.</li>
<li>It achieves good transparency without yellow tint and a slight whitish glazing effect depending on formulation principle & loading in clear coats.</li>
<li>It exhibits good wettability even using binders with low polarity, and excellent dispersion properties even without grinding.</li>
<li>It retains the excellent properties of the base material as it possesses very high- brightness & color-neutrality, relatively low abrasivity, low sieve residues and low moisture content.</li>
<li>As compared with the base, Aktifit® VM minimizes yield point & low shear viscosity and offers excellent mechanical properties such as increased tensile-, flexural- & impact strength.</li>
<li>The recommended dosage level is up to 55% depending on the intended application likewise up to PVC 35.</li>
<li>It has a shelf life of 2 years.</li></ul> Aktifit® AM by Hoffmann Mineral acts as a functional filler.
