High‑Gloss Barium Sulfate for Powder Coatings
Our high‑purity barium sulfate (BaSO₄, CAS 7727‑43‑7) is a special filler for high‑gloss powder coatings. It has ultra‑fine particles, low oil absorption and great dispersibility. It delivers mirror‑smooth high‑gloss surface, stable color and excellent weather‑resistance. It improves coating hardness and anti‑aging performance. Suitable for home appliance, hardware and architectural powder coatings. It can partially replace titanium dioxide to cut formulation costs.
