Oil‑Soluble Manganese Drier 8% Mn CAS 15956-58-8 for Long Oil Alkyd and Printing Ink
Oil‑Soluble Manganese Drier 8% Mn CAS 15956‑58‑8 is oil‑soluble manganese‑based through drier with 8% manganese metal content. It is developed for long‑oil alkyd coatings and printing ink. It synergizes with cobalt primary drier to boost full‑film through‑curing, prevents soft bottom defect. It features excellent solubility in alkyd resins and ink carriers, stable catalytic activity, widely used in air‑dry alkyd paint and oxidative printing ink production.
Product Overview
Oil‑Soluble Manganese Drier 8% Mn CAS 15956‑58‑8 is manganese 2‑ethylhexanoate acting as classic through drier. Different from cobalt surface drier, it mainly accelerates oxidative cross‑linking inside paint and ink film. When combined with cobalt drier, it balances surface drying and inner‑layer curing, avoids surface skinning while substrate remains soft. It dissolves well in aliphatic‑aromatic hydrocarbon solvents, long‑oil alkyd resins and printing ink vehicles. It maintains steady catalytic performance during storage and industrial batching, adapts to both coating and ink manufacturing processes.
Key Features
‑ 8% manganese content, moderate and stable through‑drying activity ‑ Good oil‑solubility, excellent compatibility with long‑oil alkyd resins ‑ Suitable for both long‑oil alkyd coatings and oxidative printing ink ‑ Synergizes with cobalt drier to realize uniform full‑film curing ‑ Reduces risks of surface skinning and uncured film bottom ‑ Compatible with zirconium, calcium and other auxiliary driers ‑ Stable performance under regular storage conditions ‑ Reliable batch‑to‑batch consistency for paint and ink mass production

Usage Recommendation
‑ Typical dosage: 0.1%‑0.45% calculated on total formula weight (as metal manganese) ‑ Premix with cobalt and other drier components before adding into paint or ink ‑ Do not add during high‑temperature resin synthesis process ‑ Adjust cobalt‑manganese ratio according to drying test results ‑ Strictly control dosage to avoid excessive film darkening ‑ Complete laboratory evaluation on drying speed and film appearance before mass‑scale production
Package & Storage
‑ Standard package: 25kg / 200kg metal drum ‑ Store in cool, dry and well‑ventilated warehouse, keep away from heat source and open flame ‑ Keep container tightly sealed after opening to prevent solvent volatilization and oxidation ‑ Shelf life: 12 months under proper storage conditions
Safety Notes
‑ Combustible liquid, keep away from all ignition sources. ‑ Avoid skin contact and eye splash. Wear chemical‑resistant gloves and safety goggles during handling. ‑ Avoid inhalation of vapor and mist, ensure effective local ventilation. ‑ Refer to SDS for full guidance on handling, transportation and emergency disposal.
