Co‑Ba‑Zn Combination Drier CAS 136‑52‑7 is ready‑to‑use composite drier blended with cobalt, barium and zinc metal carboxylates. Cobalt provides fast surface oxidative drying for ink film. Barium promotes inner‑layer through‑curing and improves ink film hardness and solvent resistance. Zinc acts as effective anti‑skinning component to restrain premature surface skin generation. This multi‑metal blend solves common printing‑ink defects such as can skinning and incomplete internal curing. It is wi

Product Detail

Product Overview

Co‑Ba‑Zn Combination Drier CAS 136‑52‑7 belongs to pre‑formulated multi‑metal carboxylate composite drier specially developed for solvent‑borne alkyd printing ink systems. Cobalt works as primary surface drier to accelerate oxidative cross‑linking of ink film. Barium enhances deep‑layer through‑curing performance and upgrades mechanical strength and chemical resistance of cured ink layer. Zinc effectively suppresses premature gelation and surface skinning inside ink container and on printing roller. It balances drying speed and storage stability, avoids printing failure caused by skin residues. It dissolves completely in aliphatic and aromatic hydrocarbon solvents, exhibits good compatibility with alkyd ink binders, maintains stable storage performance and consistent batch‑to‑batch quality.

Key Features

‑ Pre‑blended Co‑Ba‑Zn three‑metal composite formula dedicated for printing ink ‑ Integrates surface drying, through‑curing and prominent anti‑skinning function ‑ Inhibits skin formation during ink storage and on‑press printing operation ‑ Barium component improves ink film hardness, abrasion and solvent resistance ‑ Balanced curing performance will not cause over‑fast surface drying or poor through‑curing ‑ Good solubility in mineral spirits and common ink‑grade hydrocarbon solvents ‑ Excellent compatibility with various alkyd resin binders for printing ink ‑ Reliable batch‑to‑batch consistency for mass‑production of solvent‑based printing ink

Application Scenarios

‑ Solvent‑borne alkyd‑based offset printing ink systems ‑ General industrial printing ink requiring anti‑skinning performance ‑ Printing ink formulations pursuing balanced surface and through‑curing ‑ Alkyd binder printing ink for packaging and graphic printing ‑ Composite drier solution for printing ink manufacturers

Usage Recommendation

‑ Typical dosage: 0.20%‑0.60% calculated on total ink weight based on total metal content ‑ Add under low‑speed mixing during letdown stage ‑ Do not add during high‑temperature resin synthesis procedure ‑ Adjust dosage according to ink drying speed, through‑curing and anti‑skinning test results ‑ Excessive dosage may lead to brittleness of ink film; 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.
