Neutral Calcium Octoate 5% Ca CAS 136‑51‑6 is neutral‑type calcium carboxylate auxiliary co‑drier. It features low‑alkali property and minimal color‑developing tendency, stabilizes curing reaction without causing obvious yellowing, perfectly suitable for pale and light‑colored low‑alkali alkyd coating systems combined with cobalt‑manganese primary driers.

Product Detail

Product Overview

Neutral Calcium Octoate 5% Ca CAS 136‑51‑6 is neutral metal carboxylate auxiliary drier for oxidative alkyd coating systems. It cannot realize curing independently and must be compounded with cobalt‑manganese primary drier sets. Basic calcium octoate may bring extra alkali content and trigger yellowing for pale coatings. This neutral‑grade product lowers alkali influence remarkably, maintains stable auxiliary curing capacity while protecting original light color of paint film. It dissolves well in aliphatic and aromatic hydrocarbon solvents, shows excellent compatibility with long‑oil and medium‑oil pale alkyd resins, and keeps stable performance during storage and industrial paint production.

Key Features

‑ 5% balanced calcium content for mild and stable auxiliary curing activity ‑ Neutral salt structure, low alkali value, reduce alkali‑caused yellowing risk ‑ Minimum color interference for pale, clear and light‑colored alkyd films ‑ Excellent synergistic stabilization effect with cobalt and manganese primary driers ‑ Improves paint film gloss, leveling and overall curing system stability ‑ Good solubility in mineral spirits, xylene and common coating solvents ‑ Fine compatibility with pale varnish and low‑alkali alkyd resin systems ‑ Reliable batch‑to‑batch consistency for high‑grade light‑color paint mass‑production

Technical Specifications

‑ Product Name: Neutral Calcium Octoate (Neutral Calcium 2‑Ethylhexanoate) ‑ Calcium Content: 5% Ca ‑ CAS No.: 136‑51‑6 ‑ Appearance: Colorless to pale yellow transparent liquid ‑ Solubility: Soluble in aliphatic, aromatic hydrocarbon solvents and alkyd resins ‑ Density: 0.93‑0.99 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%

Application Scenarios

‑ Pale clear alkyd varnish and light‑colored decorative alkyd coatings ‑ Low‑alkali industrial finishing alkyd systems ‑ High‑grade furniture alkyd paint requiring low yellowing performance ‑ Light‑toned alkyd enamel sensitive to alkali‑induced discoloration ‑ Composite drier formula cooperating with cobalt and manganese primary driers

Usage Recommendation

‑ Typical dosage: 0.10%‑0.38% calculated on total paint weight (as metal calcium) ‑ Premix sufficiently 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 required ‑ Adjust dosage according to curing test and anti‑yellowing color stability 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.
