Cobalt‑Free Manganese Complex Drier Low‑Yellowing for White Paint Water‑Solvent
Cobalt‑Free Manganese Complex Drier is cobalt‑free manganese complex primary drier designed for white and light‑colored paint. Thanks to special complex modification technology, it delivers effective oxidative curing while keeping low‑yellowing performance. This product is compatible with solvent‑borne and water‑dilutable alkyd systems. It needs to work with suitable auxiliary driers to realize balanced surface drying and through‑curing. It is widely applied in white, off‑white and pastel‑tone d
Product Overview
Cobalt‑Free Manganese Complex Drier belongs to cobalt‑free complex‑type primary drier for water‑solvent dual‑system alkyd coatings. Conventional cobalt‑containing driers easily cause yellowing and shade deviation for white paint. This modified manganese complex structure realizes oxidative cross‑linking without cobalt, greatly reducing yellowing risk for white and light‑colored coatings. It exhibits good compatibility in both solvent‑borne hydrocarbon systems and water‑dilutable alkyd environments. As primary drier, it shall cooperate with auxiliary driers to improve through‑curing, film hardness and storage stability. It maintains stable storage performance and consistent batch‑to‑batch quality.
Key Features
‑ Cobalt‑free modified manganese complex primary drier, eco‑friendly cobalt substitute ‑ Excellent low‑yellowing performance, suitable for white and light‑toned paint formulations ‑ Water‑solvent dual‑use compatibility for solvent‑borne and water‑dilutable alkyd resins ‑ Provides reliable oxidative catalytic curing activity without cobalt component ‑ Can be compounded with matched auxiliary driers to optimize overall curing profile ‑ Good miscibility with different‑polarity alkyd binders ‑ Meets environmental requirements for low‑metal decorative and industrial coatings ‑ Reliable batch‑to‑batch consistency for mass‑production of white and pale‑color alkyd paints

Application Scenarios
‑ White, off‑white and pastel‑shade solvent‑borne alkyd decorative paints ‑ Light‑color water‑dilutable alkyd coating systems ‑ Industrial light‑toned top‑coat enamels requiring low yellowing performance ‑ Cobalt‑free paint projects for both solvent‑borne and water‑dilutable alkyd ‑ Primary drier component cooperating with auxiliary driers for complete curing system
Usage Recommendation
‑ Typical dosage: 0.20%‑0.60% calculated on total paint weight ‑ Add under low‑speed mixing during pigment letdown stage ‑ Do not add during high‑temperature resin synthesis procedure ‑ Must combine with proper auxiliary driers to enhance through‑curing and film mechanical properties ‑ Evaluate yellowing resistance under real‑world light‑aging test conditions ‑ Excessive dosage may trigger slight color shift; complete full‑set laboratory assessment 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 direct sunlight ‑ Tightly seal container after opening to prevent solvent volatilization and performance deterioration ‑ 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.
