Import Fac-4 Air Entraining Agent — Buy in Bulk from Supplier in China

The FAC-4 Air entraining agent is a concrete admixture designed to introduce microscopic air bubbles that improve workability, durability and freeze‑thaw resistance. It is supplied in bulk, with packaging sizes that can be tailored to order. The agent is compatible with many cement types and helps maintain strength while increasing durability. Its action reduces the risk of frost damage and cracking in cold environments.

Air‑entraining agents are typically based on surfactant chemistries that generate stable air voids of 150‑300 µm. Typical dosage for such agents is 0.05%‑0.3% by weight of cement, providing an air content of 5‑10% (typical). FAC-4 follows this conventional formulation and is free from hazardous additives, aligning with standard construction practice. The product’s compatibility with various cement grades makes it suitable for both commercial and residential projects.

The primary market includes contractors, ready‑mix producers and precast manufacturers operating in regions where freeze‑thaw cycles are a concern. The supplier offers bulk supply options, but exact minimum order quantities, lead times and payment conditions must be clarified directly with the company. Prospective buyers should request the product data sheet and confirm compliance with ASTM C‑260 for air‑entraining admixtures. Proper storage in a dry, temperature‑controlled warehouse preserves the admixture’s effectiveness.

Beijing Ruidisi Building Materials Co., Ltd is located at No 600 Chaichangtun Village, Yongledian Town, Tongzhou District, Beijing 101115, China. The company is classified as an imported tier supplier and holds a harbour-level trust rating on the platform. It supplies a range of concrete chemical additives, including antifreeze and air‑entraining agents, for projects both within China and abroad.

The supplier’s response data shows a response rate of 0% and no average response time, meaning enquiries may need follow‑up. Listings provide technical overviews but omit detailed certification documents, so buyers should ask for any necessary test reports.
