Corrosion Inhibitors & Coatings

​PBTC (2-phosphonobutane-1,2,4-tricarboxylic acid), technical grade. Slightly yellow liquid, minimum 50% active. Excellent dispersant and corrosion inhibitor, effective at low concentrations, compatible with high-hardness water and any water ratio. Improves dispersibility through adsorption of suspended inorganic particles. Highly stable against chlorine and bleaches, ideal for industrial and household cleaning formulations and water treatment. Properties: pH (1% solution) 2.0–3.0, density at 20 °C of 1.28–1.38 g/cm³. CAS 37971-36-1. Available in Monterrey, with shipping throughout Mexico.

Sodium gluconate, technical grade. Fine crystalline white powder, ≥ 98% purity. Highly soluble in water, non-corrosive, and non-toxic, with excellent resistance to oxidation and reduction even at high temperatures. Functions as a set retarder, plasticizer, and water reducer in cementitious systems. Applications: concrete, mortars, plasters, and other construction formulations. Properties: assay ≥ 98.0%, whiteness 55.5–85.0%, reducing substances ≤ 0.50%, chlorides ≤ 0.05%, sulfates ≤ 0.05%, heavy metals (Pb) ≤ 5.0 mg/kg, arsenic ≤ 1.0 mg/kg, pH (5% solution) 6.0–8.0, CAS 527-07-1. Also known as: sodium gluconate. Available in Monterrey, with shipping throughout Mexico.
