Co‑Zr Mixed Metal Drier CAS 136‑52‑7 is ready‑to‑use composite drier blended with cobalt and zirconium metal carboxylates. Cobalt offers fast surface oxidative drying, while zirconium promotes inner‑layer cross‑linking through‑curing. This two‑metal blend avoids incomplete inner‑layer curing defects, works well for clear varnish as well as pigmented alkyd enamels. It simplifies formulation operation for paint manufacturers, widely used for architectural varnishes, general industrial clear coats

Product Detail

Product Overview

Co‑Zr Mixed Metal Drier CAS 136‑52‑7 belongs to pre‑formulated mixed‑metal carboxylate composite drier for air‑drying alkyd coating systems. Cobalt component acts as primary surface drier to accelerate surface oxidation cross‑linking. Zirconium functions as high‑efficiency through‑curing component to improve cross‑linking density of inner paint layer. This pre‑mixed drier balances surface drying speed and deep‑layer curing degree, applicable for both clear transparent varnish and various pigment‑containing alkyd formulations. It dissolves completely in aliphatic and aromatic hydrocarbon solvents, exhibits good compatibility with long‑oil and medium‑oil alkyd resins, maintains stable storage property and consistent batch‑to‑batch quality.

Key Features

‑ Pre‑blended cobalt‑zirconium two‑metal composite formula for convenient dosing ‑ Combined surface drying and deep‑layer through‑curing dual‑function performance ‑ Excellent compatibility for both clear varnish and pigmented alkyd systems ‑ Reduces inner‑layer soft‑curing defect of alkyd thick‑film coatings ‑ Simplifies drier formulation and reduces separate addition of multiple single‑metal driers ‑ Good solubility in mineral spirits, xylene and conventional coating hydrocarbon solvents ‑ Stable curing performance for decorative and general industrial alkyd coatings ‑ Reliable batch‑to‑batch consistency for mass‑production of clear and pigmented alkyd paints

Technical Specifications

‑ Product Name: Co‑Zr Mixed Metal Drier ‑ Active Metal: Cobalt, 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: 0.93‑0.99 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%

Application Scenarios

‑ Clear alkyd varnish and transparent top‑coat systems ‑ General pigmented decorative and industrial solvent‑borne alkyd enamels ‑ Long‑oil and medium‑oil air‑drying alkyd coating formulations ‑ Alkyd production requiring combined surface and through‑curing performance ‑ Pre‑blended composite drier solution for paint formulators

Usage Recommendation

‑ Typical dosage: 0.18%‑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 needs additional dosing according to actual storage requirement ‑ Excessive dosage may cause skinning risk, adjust dosage according to surface‑dry, through‑curing and film property test ‑ 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.
