CASIFLUX F 75 is a finely ground, high aspect ratio wollastonite mineral filler specially developed for applications demanding increased strength, scratch and heat resistance. CASIFLUX F 75 retains the needle-shaped structure providing reinforcement. Its high aspect ratio and alkaline nature make it an ideal auxiliary filler improving corrosion resistance by anodic and alkaline oxidative passivation. It acts as a pH buffer for improved stability over long periods and prevents corrosion. CASIFLUX F 75 reinforcement ability and passivating properties are successfully harnessed formulating anti-corrosion products, whilst increased crack and chip resistance is achieved in applications.
