Import Fac-1 Naphthalene-Based Super Plasticizer — Buy in Bulk from Supplier in China

The FAC-1 Naphthalene-based super plasticizer is a high-range water-reducing admixture formulated from sulfonated naphthalene formaldehyde condensates. It reduces water content in concrete mixes by up to 30% while maintaining workability, as stated in the product data. The product appears in liquid form with a specific gravity of approximately 1.08 to 1.12 and a pH range of 7 to 9, consistent with standard industry formulations for naphthalene sulfonate superplasticizers.

This admixture is typically used in ready-mix and precast concrete applications where low water-cement ratios are required for high early and ultimate strength. It is compatible with Portland cement types I through V and common supplementary cementitious materials such as fly ash and slag. The formulation does not contain chloride ions, making it suitable for reinforced concrete. Typical dosage ranges from 0.1% to 0.5% by weight of cement, depending on desired slump and ambient conditions.

Buyers in the construction sector, including precast manufacturers, highway contractors, and high-rise builders, source this product for projects requiring durable, low-permeability concrete. It is packaged in 200 kg drums or 1,000 kg IBC totes, with bulk delivery available upon request. Trade terms include FOB China port and CIF destination, with lead times typically ranging from 7 to 14 days after order confirmation. Minimum order quantities are not specified in the listing and should be confirmed directly with the supplier.
