Waterborne High‑Zr Co‑Zn‑Zr Drier CAS 136-52-7 for Thick Film Water Alkyd
Waterborne High‑Zr Co‑Zn‑Zr Drier is water‑dispersible multi‑metal composite drier with elevated zirconium content. Cobalt provides fast surface drying, zinc reduces pigment adsorption loss of drier components, high‑content zirconium greatly enhances deep‑layer through‑curing capacity, specially designed for thick‑film water‑reducible alkyd applications. Hydrophilic modification gives excellent water dispersibility and anti‑hydrolysis stability in aqueous paint matrix. It effectively avoids the
Product Overview
Waterborne High‑Zr Co‑Zn‑Zr Drier belongs to high‑zirconium‑formulated composite drier targeting thick‑film oxidative‑cure water‑reducible alkyd coatings. Conventional all‑in‑one waterborne driers usually suffer insufficient deep‑curing performance when film thickness increases, resulting in sticky inner layer, slow hardening and poor film integrity. This product retains cobalt as primary drier for surface oxidation cross‑linking, zinc inhibits drier adsorption by pigments, and raises zirconium proportion to strengthen deep‑film through‑drying effect. With hydrophilic modification technology, the drier disperses stably in water‑based system and resists hydrolysis deactivation. It is compatible with long‑oil and medium‑oil water‑reducible alkyd resins and maintains stable batch‑to‑batch quality.
Key Features
‑ High‑Zr‑formulated Co‑Zn‑Zr composite drier, cobalt raw material CAS 136‑52‑7 ‑ Specially optimized for thick‑film / high‑build water‑reducible alkyd coating systems ‑ High zirconium loading delivers powerful deep‑layer through‑drying performance ‑ Cobalt ensures rapid surface drying; zinc minimizes pigment‑induced drier loss ‑ Good water dispersibility and hydrolysis resistance, stable activity in aqueous paint environment ‑ Solves common thick‑coat defects: surface dry but inner uncured, slow hardness development ‑ Compatible with various pigments, fillers and water‑reducible alkyd binders ‑ Reliable batch‑to‑batch consistency for mass‑production of heavy‑build waterborne alkyd paints

Usage Recommendation
‑ Typical dosage: 0.25%‑0.65% calculated on total paint weight ‑ Add under low‑speed stirring at paint letdown stage, avoid high‑shear violent agitation ‑ Do not add during high‑temperature resin synthesis procedure ‑ Conduct full formula pre‑test focusing on through‑drying speed, hardness evolution, anti‑skinning and gloss performance ‑ Excessive dosage will cause skinning and yellowing risk; strictly control addition amount ‑ Complete full‑set laboratory assessment before mass‑scale production
