What is Manganese stearate?
Manganese stearate (CAS 3353-05-7) is a metal soap derived from stearic acid and manganese, a dry powder for coatings, polymer, and lubricant applications.
Where is Manganese stearate used?
- Coatings: through-drying catalyst in alkyd and oxidative-cure systems, promoting oxygen crosslinking within the paint film
- Polymers: internal lubricant and processing aid in PVC and polyolefin compounds, reducing friction during extrusion and calendering
- Adhesives and sealants: surface modification for substrate wetting and adhesion
- Metalworking lubricants: film formation and reduced metal-on-metal contact under boundary lubrication
- It also functions as a drier, plasticizer, and surface modifier in industrial formulations.
Commercial specifications
- Technical grade; purity defined by metal content and acid value
- Packaging in bags or fiber drums
