Drying Accelerator Additive for Co‑Zr‑Ca Drier System Shorter Cure Time Alkyd
Drying Accelerator Additive is high‑efficiency curing booster designed to cooperate with Co‑Zr‑Ca multi‑metal drier systems. It does not replace cobalt, zirconium or calcium driers, but reinforces catalytic reaction efficiency of original drier combination. It noticeably shortens surface‑dry and hard‑dry time for alkyd coatings, accelerates cross‑linking reaction, and will not bring obvious negative influence on film gloss and hardness. It is suitable for decorative alkyd, industrial protective
Product Overview
Drying Accelerator Additive is functional curing booster for established Co‑Zr‑Ca drier systems of air‑drying alkyd coatings. In practical production, many alkyd formulations adopt fixed Co‑Zr‑Ca drier dosage to control skinning risk, but suffer long curing cycle especially under low‑temperature construction environment. This accelerator works synergistically with cobalt‑zirconium‑calcium drier components to boost oxidation cross‑linking rate. It shortens cure time without large‑scale adjustment of existing drier proportion. It features good compatibility with long‑oil and medium‑oil alkyd resins, dissolves well in conventional coating hydrocarbon solvents, and maintains stable batch‑to‑batch performance. This product is an auxiliary additive instead of primary drier, and must be used together with complete Co‑Zr‑Ca drier system.
Key Features
‑ Special‑purpose drying accelerator matched for Co‑Zr‑Ca multi‑metal drier system ‑ Greatly shortens surface‑dry and hard‑dry cycle without reformulating main drier ratio ‑ Synergistically enhances catalytic efficiency of original cobalt‑zirconium‑calcium drier blend ‑ No obvious negative impact on gloss, hardness and other core film properties ‑ Effectively improves curing speed under low‑temperature application conditions ‑ Good solubility in mineral spirits, xylene and common coating hydrocarbon solvents ‑ Compatible with decorative and industrial solvent‑borne alkyd resin systems ‑ Reliable batch‑to‑batch consistency for alkyd paint mass‑production lines
Technical Specifications
‑ Product Name: Drying Accelerator Additive ‑ Active Component: Catalytic accelerating complex ‑ Appearance: Light yellow transparent liquid ‑ Solubility: Soluble in aliphatic, aromatic hydrocarbon solvents and alkyd resins, insoluble in water ‑ Density: 0.88‑0.94 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ Solvent‑borne alkyd coatings adopting Co‑Zr‑Ca composite drier system ‑ Decorative architectural alkyd paints with expected shorter curing time ‑ General‑purpose industrial air‑drying alkyd enamels and protective finishes ‑ Alkyd formulations with slow‑curing issue under low‑temperature construction ‑ Auxiliary booster additive for existing mature alkyd paint formulas
Usage Recommendation
‑ Typical dosage: 0.05%‑0.25% calculated on total paint weight ‑ Add under low‑speed mixing during pigment letdown stage ‑ Do not add during high‑temperature resin synthesis procedure ‑ Must be used together with complete Co‑Zr‑Ca drier system, cannot be used alone ‑ Higher dosage brings faster curing, meanwhile increases skinning risk; strictly control adding amount ‑ Test drying speed, anti‑skinning performance and final film performance in laboratory 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.
