Specialty Additives

Specialty Additives from Lubrizol are engineered to deliver unique and powerful capabilities for paints, coatings and inks. Our portfolio of high-performance, specialty additives for both solvent-borne and water-borne formulas includes corrosion inhibitors, adhesion promoters, rheology control agents, and humectants.

Corrosion Inhibitors

Lubrizol is a recognized leader in chemistry for metal coating protection, of which corrosion protection is a key element. Lubrizol corrosion inhibitor technologies are designed to protect ferrous metal, zinc alloy and aluminum substrates. Available for both water-borne and solvent-borne coating systems, our corrosion inhibitors are commonly used as components in direct-to-metal coatings, primer formulations. Lubrizol® 2064 is an acid scavenging calcium sulfonate designed for use in oil-based and water-reducible rust-proofing applications. Lubrizol® 219 is an organo-phosphate-zinc complex that provides thin film corrosion protection for solvent-borne coatings. Solplus™ AC100 is a nitrate-free flash rust inhibitor for water-borne coatings,

Adhesion Promoters

Lubrizol Adhesion Promoters are phosphate ester and hydroxyl functional polymers that improve adhesion of water-borne and solvent-borne coatings and inks to ferrous metal, zinc alloy and aluminum substrates. These performance additives can also be used for stabilizing aluminum and other metallic effect pigments in water-borne systems, especially for the prevention of gassing and corrosion.

Rheology Control Additives

Lubrizol offers a wide range of rheology control additives for improving the performance of many paints, coatings, inks and pigment concentrates. Solthix™ Rheology Modifiers utilize associative thickening mechanisms to provide efficient sag control for improved leveling and pigment/particle suspension in both ambient and thermally cured applications. The Solthix™ A series contains water-borne alkali swellable thickeners that provide thixotropic (shear thinning) viscosity modification. Depending on the degree of hydrophobic modification, a range of yield values and shear response is achievable. For non-aqueous applications, Solthix™ acrylic copolymer and Ircogel™ overbased sulfonate gel technologies are available. Solthix™ rheology control agents for solvent-borne paints and coatings improve sag control and anti-settling in pigmented applications. Ircogel™ additives are particularly effective for thermal sag prevention and anti-settling in aliphatic solvent- and plastisol-based coatings and inks.
