Low‑VOC Co‑Zr Combination Drier CAS 136-52-7 Eco High Solids Alkyd Drier
Low‑VOC Co‑Zr Combination Drier CAS 136‑52‑7 is pre‑mixed composite drier consisting of cobalt and zirconium carboxylates with low‑volatility carrier. Cobalt delivers rapid surface oxidative curing, zirconium promotes inner‑layer cross‑linking. The low‑VOC carrier avoids raising total VOC value of high‑solids systems. It balances surface‑dry speed and through‑curing performance, suitable for eco‑friendly high‑solids industrial alkyd varnishes and pigmented enamels.
Product Overview
Low‑VOC Co‑Zr Combination Drier CAS 136‑52‑7 belongs to low‑VOC pre‑formulated mixed‑metal carboxylate drier for air‑drying alkyd coating systems. Conventional Co‑Zr drier with ordinary diluent will increase volatile organic content for high‑solid formulas. This grade adopts low‑volatility carrier to control additional VOC input. Cobalt acts as primary surface drier to accelerate surface oxidation cross‑linking. Zirconium serves as through‑curing component to improve inner‑layer cross‑linking density. It solves defects of slow inner curing while complying with emission regulations. It shows good miscibility with high‑viscosity high‑solids alkyd resins, maintains stable storage performance and consistent batch‑to‑batch quality.
Key Features
‑ Pre‑blended cobalt‑zirconium two‑metal composite formula with low‑VOC carrier system ‑ Low volatile contribution, suitable for high‑solids alkyd with strict VOC limitations ‑ Balanced surface drying and deep‑layer through‑curing dual‑function performance ‑ Reduces incomplete inner‑layer curing risk for thick‑film high‑solid alkyd coatings ‑ Good compatibility with both clear varnish and pigmented high‑solids alkyd systems ‑ Simplifies drier dosing operation for high‑solid paint formulators ‑ Good miscibility with long‑oil and medium‑oil high‑solids alkyd resins ‑ Reliable batch‑to‑batch consistency for eco‑friendly high‑solids alkyd paint production

Usage Recommendation
‑ Typical dosage: 0.20%‑0.58% calculated on total paint weight based on total metal content ‑ Add under low‑speed mixing during pigment letdown stage ‑ Do not add during high‑temperature resin synthesis procedure ‑ Anti‑skin agent should be added separately according to storage requirement ‑ Evaluate VOC indicator, surface‑dry time and through‑curing performance simultaneously ‑ Excessive dosage may trigger surface skinning risk; 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 open flame ‑ 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.
