Barium Octoate 12.5% Ba CAS 2457‑01‑4 is liquid barium 2‑ethylhexanoate auxiliary drier containing 12.5% barium metal content. As a typical lead‑free through drier, it mainly promotes deep‑layer cross‑linking curing of thick alkyd films. When combined with cobalt‑manganese primary driers, it boosts film hardness, water resistance and chemical resistance, reduces film brittleness. It is widely used for heavy‑duty industrial alkyd primers, anti‑corrosive coatings and thick‑film protective alkyd sy

Product Detail

Product Overview

Barium Octoate 12.5% Ba CAS 2457‑01‑4 belongs to octoate‑series metal carboxylate auxiliary drier for air‑drying alkyd coating systems. It cannot realize independent drying effect and must be compounded with cobalt‑manganese primary drier combinations. It focuses on through‑curing of thick paint layers, solving incomplete inner‑layer curing defects of heavy‑duty thick‑film alkyd coatings. It enhances cross‑linking density of cured films, improves water resistance, solvent resistance and surface hardness. It dissolves freely in aliphatic and aromatic hydrocarbon solvents, maintains good compatibility with long‑oil, medium‑oil and partial short‑oil alkyd resins, keeps stable performance in finished paint storage and industrial batch‑to‑batch production.

Key Features

‑ 12.5% standard barium content for stable through‑curing auxiliary performance ‑ Lead‑free formula, compliant with modern environmental‑friendly coating requirements ‑ Excellent deep‑layer curing capacity, ideal for heavy‑duty thick‑film alkyd coatings ‑ Greatly improves paint film hardness, water resistance and chemical resistance ‑ Excellent synergistic matching property with cobalt and manganese primary driers ‑ Optimizes cross‑linking density, reduces soft inner‑layer curing defects ‑ Good solubility in mineral spirits, xylene and conventional coating solvents ‑ Reliable batch‑to‑batch consistency for industrial heavy‑duty protective paint production

Technical Specifications

‑ Product Name: Barium Octoate (Barium 2‑Ethylhexanoate) ‑ Barium Content: 12.5% Ba ‑ CAS No.: 2457‑01‑4 ‑ Appearance: Pale yellow transparent liquid ‑ Solubility: Soluble in aliphatic, aromatic hydrocarbon solvents and alkyd resins ‑ Density: 1.08‑1.14 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%

Application Scenarios

‑ Heavy‑duty industrial solvent‑borne alkyd protective coatings ‑ Anti‑corrosion alkyd primers and thick‑film industrial enamels ‑ Long‑oil and medium‑oil alkyd systems requiring improved through‑curing property ‑ Alkyd formulations pursuing lead‑free environmental‑friendly specifications ‑ Composite drier system cooperating with cobalt‑manganese primary driers

Usage Recommendation

‑ Typical dosage: 0.08%‑0.32% calculated on total paint weight (as metal barium) ‑ Premix fully with cobalt, manganese and other drier additives before adding into coating formula ‑ Do not add during high‑temperature resin synthesis procedure ‑ Standalone use is ineffective, cobalt‑manganese primary drier combination is mandatory ‑ Adjust dosage according to through‑curing test, hardness and water‑resistance evaluation ‑ 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.
