What we make
Solubras develops the sulfonates, inhibitors, waxes and coatings formulators rely on to keep metal surfaces clean, dry and corrosion-free, from the metalworking line to long-term outdoor storage.
Sodium, neutral and overbased calcium, and barium sulfonates for metalworking fluids, lubricants and corrosion control.
Barium-free calcium-sulfonate packages that pass demanding salt-spray and humidity exposure.
Thick- and thin-film systems for temporary protection during storage, transport and machining.
Six decades of manufacturing scale in Brazil, represented and supported from New York.
Sustainability
Every process at our plant but the reactors runs on on-site solar generation, and our practices earned the Selo Verde green seal for socio-environmental responsibility.
Latest news
After more than six decades supplying chemistry from Brazil, Solubras Chemicals LLC has established a U.S. Technical Sales Office in New York. From here we support and supply formulators across North America, with shipping to the United States, Canada, Mexico and Europe.

Barium-Free Calcium-Sulfonate Rust-Preventive Package
Calcium sulfonate (barium-free)
A calcium-based protective package, completely free of barium and heavy metals, engineered as a high-performance anti-rust base with outstanding salt-spray and water-displacing performance.
Overbased Calcium Sulfonate, 400 TBN
Overbased calcium sulfonate
A high-alkalinity (400 TBN) overbased calcium sulfonate used as a detergent and TBN booster in lubricants, as a corrosion inhibitor in protective oils, and as the feedstock for calcium-sulfonate greases.
Sodium Petroleum Sulfonate (Emulsifier)
Sodium petroleum sulfonate
A soluble sodium petroleum sulfonate used as an emulsifier and rust inhibitor in soluble and semi-synthetic metalworking fluids, and as a corrosion inhibitor in rust-preventive process oils.
Neutral Barium Sulfonate
Neutral barium sulfonate
A neutral barium petroleum sulfonate used as a film-forming corrosion inhibitor in rust-preventive oils, protective films and lubricant formulations.
Paraffinic Wax Protective Base
Paraffinic protective wax
A solid paraffinic protective wax developed for the formulation of temporary anti-corrosion oils and films, soluble in petroleum solvents for flexible compounding.
Thick-Film Solvent Rust-Preventive Coating
Oxidized / saponified petrolatum
A thick-film, solvent-deposited anti-rust coating for outdoor and long-term metal storage, leaving a residual film highly resistant to salt water and salt spray.
Thick-Film Waxy Rust-Preventive Coating
Waxy petrolatum, solvent-borne
A thick-film, waxy anti-rust protective applied as a solution in hydrogenated solvent. The dark residual film resists salt water and salt spray, protecting metal through long-term outdoor storage, even at low temperatures.
Industries
From metalworking fluids to long-term storage, our sulfonates and rust-preventive chemistry protect metal across the industries that depend on it.
Sodium-sulfonate emulsifiers and corrosion inhibitors that build stable emulsions and protect freshly machined ferrous surfaces in soluble and semi-synthetic metalworking fluids.
A full range of rust-preventive chemistry, from barium-free additive packages to thick-film coatings, that shields metal through machining, storage, sea freight and high-humidity transit.
Overbased and neutral sulfonates that bring alkalinity reserve, detergency and corrosion protection to lubricants, and supply the feedstock for high-performance calcium-sulfonate greases.
Sulfonate corrosion inhibitors that improve flash-rust control, adhesion and barrier performance in anti-corrosive primers and direct-to-metal industrial coatings.
