Manganese dioxide

Manganese dioxide (CAS 1313-13-9 ) is an inorganic mineral compound used across coatings, printing, and personal care industries as a drying catalyst, pigment, and oxidizing agent. It accelerates oxidative cross-linking in oil-based systems and contributes brown-black coloration in pigment applications. In alkyd and oil-based coatings, it functions as a drying agent. The compound catalyzes the oxidative polymerization of drying oils to reduce cure times and improve film hardness. Printing ink formulators incorporate it as a black pigment and drying promoter. This is particularly useful in oil-based ink systems for packaging applications requiring fast set times. In personal care, it is used in certain hair coloring and oxidative cosmetic formulations. Adhesive and sealant manufacturers use it as a curing accelerator in polysulfide-based systems. It drives crosslinking to achieve target mechanical properties in industrial applications. Manganese dioxide is supplied as a fine black powder in technical and battery grades. Particle size and purity specifications vary significantly depending on the specific end-use application. Technical grade material is standard for coatings and adhesive applications, while higher-purity grades are available for specialty formulations. Bulk supply is common in 25 kg bags. Larger packaging options are available for industrial volumes to meet high-capacity manufacturing needs. This ensures consistent supply chains for global chemical distribution networks.
