Manganese Octoate 6% Mn CAS 15956-58-8 Through Drier for Alkyd Coating with Cobalt
Manganese Octoate 6% Mn CAS 15956‑58‑8 is oil‑soluble manganese‑based through drier with 6% manganese metal content. It is widely matched with cobalt primary surface drier for alkyd coatings. It accelerates oxidative cross‑linking inside paint film to realize through‑drying effect, avoids surface skinning caused by surface‑only drying. It features good resin compatibility and stable catalytic property for general‑purpose alkyd paint manufacturing.
Product Overview
Manganese Octoate 6% Mn CAS 15956‑58‑8 is oil‑soluble manganese 2‑ethylhexanoate, acting as classic through drier for oxidative alkyd coating. Different from cobalt‑based surface drier, its main function is to boost curing reaction inside coating film. When compounded with cobalt drier, it balances surface drying and inner‑layer curing, effectively preventing surface wrinkling, skinning and poor through‑dry issues. It dissolves well in hydrocarbon solvents and various alkyd resins, and maintains stable drier activity during storage and industrial production.
Key Features
‑ 6% manganese content, reliable through‑drying catalytic performance ‑ Oil‑soluble, excellent miscibility with long‑oil and medium‑oil alkyd resins ‑ Works synergistically with cobalt drier to achieve full‑film curing ‑ Solves poor inner‑layer drying problem of alkyd coating systems ‑ Reduces risks of surface skinning, wrinkling and soft film bottom ‑ Compatible with zirconium, calcium and other metal driers ‑ Stable catalytic activity under normal storage conditions ‑ Consistent batch‑to‑batch quality for large‑scale alkyd paint production
