Aktisil® MM

Aktisil® MM by Hoffmann Mineral acts as a functional filler. It is an agglomerate of corpuscular silica and lamellar kaolinite. It is an activated Sillitin® Z 86, produced by modifying the surface with a mercapto functional group. It can be used either on its own or combined with other extenders or flatting agents in paint and varnish applications.

• It retains the excellent properties of the base material as it possesses high filling ratio, outstanding dispersion behavior, good pigment dispersion (spacer effect), low abrasiveness, very low tendency to settle, and good flatting effect.
• It is quick-drying, has a matting effect, and shows breathability, good scratch-, abrasion- & weathering-, chemical- and moisture resistance.
• Optimum performance is achieved in binder systems which have functional groups with active hydrogen or which polymerize or cure as a result, including amine-type or carboxylic anhydride-cured epoxy-, melamine-, UF resins- and phenol formaldehyde resin.
• As compared with the base, Aktisil® MM minimizes yield point (including a high solids content) and offers excellent mechanical properties such as increased tensile-, bending-, wet edge- & impact strength.
• It exhibits good wettability even using binders with low polarity, good transparency and improved swelling characteristics.
• It is suitable for high-grade, reactive industrial paints, stoving paints/enamels-, and anti-corrosive coatings.
• The recommended metering level is up to 50% depending on intended application.
• The shelf life of product is 3 years.
