Balanced Co‑Ca‑Zr Combination Drier CAS 136-52-7 for Industrial Decorative Alkyd
Balanced Co‑Ca‑Zr Combination Drier CAS 136‑52‑7 is ready‑to‑use composite drier blended with cobalt, calcium and zirconium metal carboxylates. Cobalt provides moderate surface oxidative drying, calcium improves gloss and curing stability, zirconium reinforces inner‑layer cross‑linking. This balanced formula avoids over‑fast surface skinning and soft under‑layer defects. It fits mass production of both decorative architectural alkyd paints and general‑purpose industrial alkyd enamels, reducing r
Product Overview
Balanced Co‑Ca‑Zr Combination Drier CAS 136‑52‑7 belongs to pre‑formulated multi‑metal carboxylate composite drier for air‑drying alkyd coating systems. Metal ratios are finely tuned for dual‑purpose industrial and decorative alkyd scenarios. Cobalt acts as primary surface drier to trigger oxidative cross‑linking on coating surface. Calcium stabilizes gloss development and improves anti‑brittleness performance of cured film. Zirconium serves as efficient through‑curing component to boost polymer network cross‑linking inside paint film. It achieves balanced drying profile without excessive surface skinning or insufficient inner curing. It dissolves completely in aliphatic and aromatic hydrocarbon solvents, shows excellent compatibility with long‑oil and medium‑oil alkyd resins, maintains stable storage property and consistent batch‑to‑batch quality.
Key Features

Usage Recommendation
‑ Typical dosage: 0.20%‑0.55% 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 can be added additionally according to actual storage requirements ‑ Adjust dosage according to surface‑dry time, through‑curing, gloss and hardness test results ‑ Excessive dosage may cause 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.
