Zirconium Neodecanoate 6% Zr CAS 51601-43-5 for Pale Alkyd with Cobalt System
Zirconium Neodecanoate 6% Zr CAS 51601‑43‑5 is oil‑soluble lead‑free zirconium‑based auxiliary drier containing 6% zirconium metal content. Based on neodecanoate structure, it delivers outstanding low‑yellowing performance and is optimized for pale alkyd coatings matched with cobalt primary drier. It boosts through‑curing reaction, upgrades film hardness, gloss and water resistance, brings minimal color shift to light‑shade films, and fits high‑grade pale alkyd varnish and decorative paint manuf
Product Overview
Zirconium Neodecanoate 6% Zr CAS 51601‑43‑5 is zirconium neodecanoate lead‑free secondary drier for oxidative alkyd coating systems. It cannot function as independent surface drier and must cooperate with cobalt drier. Compared with conventional zirconium octoate, neodecanoate molecular structure effectively reduces film yellowing tendency, which is critical for pale and clear alkyd formulas. It accelerates inner‑layer cross‑linking, improves mechanical properties of paint film. It dissolves well in dearomatized aliphatic solvents and various alkyd resins, maintains stable catalytic activity during storage and industrial batch production.
Key Features
‑ 6% zirconium content for mild and stable auxiliary through‑drying performance ‑ Lead‑free eco‑friendly formulation complying with modern coating regulations ‑ Low‑yellowing property, minimum color interference for pale alkyd films ‑ Optimized matching performance with cobalt primary drier system ‑ Improves coating hardness, surface gloss and water‑resistant performance ‑ Excellent solubility in dearomatized solvents and light‑color alkyd resins ‑ Good compatibility with long‑oil and medium‑oil pale alkyd resins ‑ Reliable batch‑to‑batch consistency for high‑grade light‑shade paint mass‑production
Technical Specifications
‑ Product Name: Zirconium Neodecanoate ‑ Zirconium Content: 6% Zr ‑ CAS No.: 51601‑43‑5 ‑ Appearance: Colorless to pale yellow transparent liquid ‑ Solubility: Soluble in mineral spirits, dearomatized solvents and alkyd resins ‑ Density: 0.87‑0.91 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥120℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ Pale‑shade and clear alkyd varnish cooperating with cobalt drier ‑ High‑grade light‑colored decorative alkyd coatings ‑ Furniture alkyd finishing paint requiring low‑yellowing property ‑ Lead‑free light‑toned industrial alkyd enamel ‑ Composite drier system with cobalt primary drier for pale alkyd formulas
Usage Recommendation
‑ Typical dosage: 0.05%‑0.30% calculated on total paint weight (as metal zirconium) ‑ Premix thoroughly with cobalt drier and other drier additives before adding into coating formula ‑ Do not add during high‑temperature resin synthesis procedure ‑ Standalone use is ineffective, cobalt drier is mandatory for curing system ‑ Adjust addition dosage according to drying test and anti‑yellowing evaluation ‑ Complete laboratory tests on curing behavior, gloss and color stability 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.
