Why MICA & Aspolit in paints? 1.) Excellent wettability due to low oil absorption 2.) Increases opacity & coverage 3.) Reduces cracking & shrinkage 4.) Reduces visibility of overlapping 5.) Ensures good adhesion 6.) Reduces pinhole effect 7.) UV, IR and chemical resistance 8.) Excellent Dispersibility 9.) Improves wet rub resistance Paints (mainly Aspolit because of abrasion)

Why MICA & Aspolit in coatings? 1.) Reducing permeability due to high aspect ratio 2.) Excellent wettability due to low oil absorption 3.) Reduces cracking & shrinkage & overlapping 4.) Ensures good adhesion 5.) UV, IR and chemical resistance Coatings 6.) Reduces pinhole effect 7.) Excellent Dispersibility

Why MICA & Aspolit in Construction? 1.) Excellent wettability due to low oil absorption 2.) Increases opacity & coverage 3.) Reduces cracking & shrinkage & overlapping 4.) Ensures good adhesion Construction 5.) UV, IR and chemical resistance 6.) Excellent Dispersibility 7.) Reduces pinhole effect 8.) Improves wet rub resistance (mainly Aspolit because of abrasion)

Why MICA & Aspolit in adhesives? 1.) Excellent combination of viscosity and tensile strength due to mineral structure 2.) Excellent wettability due to low oil absorption 3.) Reduces cracking & shrinkage 4.) Chemical resistance Adhesives 5.) Ensures good adhesion 6.) Excellent Dispersibility

Why MICA in plastics and compounds? 1.) Improves mechanical strength & stiffness 2.) Low electric conductivity – isolation effect 3.) Reduces cracking & shrinkage & overlapping 4.) Excellent wettability due to low oil absorption 5.) Improves heat resistance 6.) Reduces pinhole effect 7.) Low thermal conductivity 8.) Excellent Dispersibility 9.) Excellent UV, IR and chemical resistance Plastics & compounds

Why MICA in decorative cosmetics? 1.) Excellent wettability due to low oil absorption 2.) Ideal filler not only for make-up, lipsticks & eyeliner 3.) REACH, CMR and Nanoparticle regulations are not applicable 4.) Extremely marginal content of heavy metals 5.) Increases opacity & coverage 6.) Reduces cracking & shrinkage 7.) Improves surface properties & adhesion Decorative cosmetics 8.) Excellent Dispersibility 9.) Basis material for pearlescent pigments

Why MICA in biological agriculture? 1.) Excellent wettability due to low oil absorption 2.) Purely organic insecticide (e.g. Pear Psyllid insect) 3.) Safe to use in the food industry – extremely marginal content of heavy metals 4.) Improves surface properties of food & vegetable 5.) Protection against russeting Biological agriculture 6.) Excellent UV resistance 7.) Excellent Dispersibility 8.) Reduction of permeability (high aspect ratio)

Industrial niches for MICA & Aspolit: 1.) Iron foundry (sand) 2.) Special paper application 3.) Refractory industry Industrial 4.) Clutch & brake pads Niches 5.) (Coloured) pencils 6.) Insulation materials 7.) Ceramics
