Co‑Ca‑Zr‑Zn All‑in‑One Drier CAS 136‑52‑7 is ready‑to‑use four‑metal composite drier blend. Cobalt provides fast surface drying, calcium stabilizes film gloss, zirconium promotes deep‑layer through‑curing, and zinc serves as anti‑skinning auxiliary component to restrain surface skin formation during paint storage. This all‑in‑one blend simplifies formula configuration, reduces the types of raw materials for formulators. It is widely used for architectural alkyd paints, general‑purpose enamels an

Product Detail

Product Overview

Co‑Ca‑Zr‑Zn All‑in‑One Drier CAS 136‑52‑7 belongs to pre‑formulated multi‑metal carboxylate composite drier for air‑drying alkyd coating systems. Four metal components are compounded in optimized proportion inside a single product. Cobalt acts as primary surface drier to accelerate oxidative cross‑linking on paint film surface. Calcium improves gloss development and curing stability. Zirconium enhances inner‑layer cross‑linking density for sufficient through‑curing. Zinc effectively suppresses premature gel and skinning defect during closed‑can storage. It solves common problems including fast surface‑dry but soft inner layer, as well as early skinning during storage. It dissolves completely in aliphatic and aromatic hydrocarbon solvents, exhibits excellent compatibility with long‑oil and medium‑oil alkyd resins, maintains stable storage property and consistent batch‑to‑batch quality.

Key Features

‑ All‑in‑one Co‑Ca‑Zr‑Zn four‑metal pre‑blended formula for convenient one‑shot addition ‑ Balanced surface drying performance and deep‑layer through‑curing capability ‑ Built‑in anti‑skinning function, obviously improves closed‑can storage stability of alkyd paint ‑ Reduces raw material varieties and simplifies drier formula operation ‑ Good gloss retention and uniform film formation for cured alkyd coatings ‑ Restrains surface skin formation without heavily slowing down drying speed ‑ Good solubility in mineral spirits, xylene and conventional coating hydrocarbon solvents ‑ Reliable batch‑to‑batch consistency for mass‑production of decorative and industrial alkyd paints

Technical Specifications

‑ Product Name: Co‑Ca‑Zr‑Zn All‑in‑One Drier ‑ Active Metal: Cobalt, Calcium, Zirconium, Zinc ‑ CAS No.: 136‑52‑7 ‑ Appearance: Purple‑reddish transparent liquid ‑ Solubility: Soluble in aliphatic, aromatic hydrocarbon solvents and alkyd resins, insoluble in water ‑ Density: 0.95‑1.01 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 ‑ Alkyd formulations requiring improved anti‑skinning closed‑can storage performance ‑ Long‑oil and medium‑oil alkyd systems with balanced drying and storage requirements ‑ All‑in‑one composite drier solution for paint formulators

Usage Recommendation

‑ Typical dosage: 0.22%‑0.62% 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 ‑ For extra long‑term storage requirement, additional anti‑skin agent can be supplemented as needed ‑ Adjust dosage according to surface‑dry time, through‑curing and closed‑can anti‑skinning test results ‑ Excessive dosage may induce brittleness 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.
