Aktisil® PF 777

Technical Datasheet | Supplied by Hoffmann Mineral
Aktisil® PF 777 by Hoffmann Mineral acts as a functional filler. It is an activated Sillitin® Z 86, produced by modifying the surface with an alkyl functional group. It can be used alone by itself, or in combination with rheological additives and/or flatting agents. It offers good transparency, improved wetting and easy dispersion in binders with low to slight polarity.
  • 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 slight flatting effect.
  • It is hydrophobic, quick-drying, and shows breathability, good scratch-, abrasion-, weathering- and chemical- (particularly acids) resistance.
  • In non-polar to slightly polar vehicle systems, Aktisil® PF 777 is easily dispersed already with low shear energy input, and provides rheological properties such as shear thinning.
  • In highly polar systems, its appropriate loadings cause thixotropic properties, strong shear thinning and lead to a yield point.
  • It is used in high solids fillers, plastic primers, high performance industrial paints, metal-, electrophoretic-, and solvent-based corrosion protection (general, polyaspartic, epoxy) coatings.
  • Recommended dosage level is up to 50% (m/m) and PVC up to appr. 30%.
  • The shelf life of product is 3 years.
