Aluminum Octoate 7% Al CAS 3002-63-9 Hardness Promoter Specialty Alkyd Drier
Aluminum Octoate 7% Al CAS 3002‑63‑9 is liquid aluminum 2‑ethylhexanoate specialty drier containing 7% aluminum metal content. Different from conventional surface or through driers, its core function is to promote cross‑linking density and boost final film hardness and scratch resistance. When compounded with cobalt‑manganese primary driers, it improves mechanical performance of cured alkyd films without obvious influence on surface drying speed. It is suitable for industrial alkyd primers, hard
Product Overview
Aluminum Octoate 7% Al CAS 3002‑63‑9 belongs to octoate‑series metal carboxylate specialty drier for air‑drying alkyd coating systems. It cannot realize independent drying effect and must be compounded with cobalt‑manganese primary drier combinations. Many standard drier packages achieve drying performance while the final paint film still suffers insufficient hardness and poor scratch resistance. This aluminum‑based drier raises cross‑linking density of polymer network, significantly lifting surface hardness and mechanical properties. It dissolves well in aliphatic and aromatic hydrocarbon solvents, maintains good compatibility with long‑oil, medium‑oil and short‑oil alkyd resins, and keeps stable performance in finished paint storage and industrial batch‑to‑batch production.
Key Features
‑ 7% standard aluminum content for stable hardness‑promoting auxiliary performance ‑ Specialty functional drier focused on increasing paint film cross‑linking density ‑ Effectively improves surface hardness, scratch resistance and mechanical property ‑ Does not cause excessive change of surface drying speed within reasonable dosage range ‑ Excellent synergistic compatibility with cobalt and manganese primary driers ‑ Good solubility in mineral spirits, xylene and conventional coating hydrocarbon solvents ‑ Optimized for industrial coatings requiring hard, tough alkyd film surface ‑ Reliable batch‑to‑batch consistency for specialty high‑hardness alkyd paint manufacturing
Technical Specifications
‑ Product Name: Aluminum Octoate (Aluminum 2‑Ethylhexanoate) ‑ Aluminum Content: 7% Al ‑ CAS No.: 3002‑63‑9 ‑ Appearance: Pale yellow transparent liquid ‑ Solubility: Soluble in aliphatic, aromatic hydrocarbon solvents and alkyd resins ‑ Density: 0.92‑0.98 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ Industrial solvent‑borne alkyd coatings pursuing high surface hardness ‑ Hard‑finish alkyd enamels and mechanical equipment protective alkyd paints ‑ Alkyd primers requiring improved scratch resistance and mechanical strength ‑ Long‑oil, medium‑oil and short‑oil specialty alkyd formulation systems ‑ Composite drier system cooperating with cobalt‑manganese primary driers
Usage Recommendation
‑ Typical dosage: 0.06%‑0.28% calculated on total paint weight (as metal aluminum) ‑ 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, primary drier combination is mandatory ‑ Excessive dosage may lead to film brittleness; adjust dosage according to hardness, flexibility and drying test results ‑ 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.
