Co‑Ca‑Zr Combination Drier CAS 136‑52‑7 is ready‑to‑use pre‑mixed drier blend composed of cobalt, calcium and zirconium metal carboxylates. Cobalt contributes fast surface drying, calcium optimizes cross‑linking stability, and zirconium promotes deep‑layer through‑curing. This one‑pack drier realizes matched surface and inner‑layer curing, reduces formulation complexity for formulators. It is widely applied for architectural alkyd paints, general industrial enamels and various conventional solve

Product Detail

Product Overview

Co‑Ca‑Zr Combination Drier CAS 136‑52‑7 belongs to pre‑formulated mixed‑metal carboxylate composite drier for air‑drying alkyd coating systems. Multiple metal components are compounded in proper proportion inside this single product, avoiding separate weighing and mixing of several single‑metal driers. Cobalt acts as primary surface drier to accelerate surface oxidative cross‑linking. Calcium improves drier stability and film gloss performance. Zirconium serves as through‑curing component to promote inner‑layer curing of paint film. The synergistic effect solves common defects such as surface skinning, soft inner layer and incomplete curing. It dissolves completely in aliphatic and aromatic hydrocarbon solvents, shows excellent compatibility with long‑oil and medium‑oil alkyd resins, maintains stable storage performance and consistent batch‑to‑batch quality.

Key Features

‑ Pre‑blended Co‑Ca‑Zr multi‑metal formula, one‑pack convenient application ‑ Perfect balance between fast surface drying and sufficient deep‑layer through‑curing ‑ Simplifies drier formula design and reduces formulating operation steps ‑ Good gloss development and stable curing performance for alkyd films ‑ Suppresses defects including surface skinning and inner‑layer soft curing ‑ Excellent solubility in mineral spirits, xylene and common coating solvents ‑ Wide compatibility with long‑oil and medium‑oil solvent‑borne alkyd resins ‑ Stable batch‑to‑batch consistency for mass‑production of decorative and industrial alkyd paints

Technical Specifications

‑ Product Name: Co‑Ca‑Zr Combination Drier ‑ Active Metal: Cobalt, Calcium, Zirconium ‑ CAS No.: 136‑52‑7 ‑ Appearance: Purple‑reddish transparent liquid ‑ Solubility: Soluble in aliphatic, aromatic hydrocarbon solvents and alkyd resins, insoluble in water ‑ Density: 0.94‑1.00 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%

Application Scenarios

‑ General‑purpose decorative solvent‑borne alkyd architectural coatings ‑ Conventional industrial air‑drying alkyd enamels and protective finishes ‑ Long‑oil and medium‑oil alkyd systems requiring balanced surface & through curing ‑ Alkyd production lines pursuing simplified drier feeding operation ‑ Ready‑mixed composite drier solution for paint formulators

Usage Recommendation

‑ Typical dosage: 0.20%‑0.60% 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 process ‑ Anti‑skin agent shall be added separately according to actual storage requirement ‑ Adjust dosage according to surface‑dry time, through‑curing and film property test ‑ Excessive dosage may induce 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.
