Cobalt‑Free Waterborne Fast Drying Accelerator for Low‑Temperature Cure Water Resin
Cobalt‑Free Waterborne Fast Drying Accelerator is cobalt‑excluded hydrophilic‑modified drying accelerator for oxidative‑cure water resins. Special multi‑metal ligand formula delivers high catalytic activity at low temperature, effectively solves slow curing defect of waterborne coatings under cold environment. It promotes both surface oxidation cross‑linking and deep‑film through‑drying performance. Hydrophilic modification brings stable water dispersibility and anti‑hydrolysis property in aqueo
Product Overview
Cobalt‑Free Waterborne Fast Drying Accelerator belongs to cobalt‑free waterborne drying accelerator specially developed for low‑temperature cure oxidative water resin systems. Conventional waterborne driers usually show insufficient catalytic activity under low‑temperature environment, resulting in extremely slow drying, sticky film and long‑time hardness development. This product adopts optimized multi‑metal complex ligand technology without cobalt heavy‑metal. It maintains high oxidative catalytic efficiency under cold condition, accelerates free‑radical cross‑linking reaction of unsaturated resin chains, improves both surface‑drying and through‑drying speed. Hydrophilic modification treatment ensures stable dispersion in aqueous paint system and prevents hydrolysis‑caused activity loss. It is compatible with various oxidative water‑based modified alkyd resins and maintains stable batch‑to‑batch quality.
