Dimer acids are synthesized via clay catalyzed reaction of C18 fatty acids. Several C18 fatty acid sources are used to produce dimer acid. Tall oil fatty acid (TOFA), with its unique fatty acid distribution, and the presence of residual rosin acids, leads to dimer acids with properties that can’t be found in dimers produced from other fatty acid sources.
TOFA’s properties lead to dimer acids with linear, branched, cyclic, aromatic, and naphthenic structures. When a TOFA-based dimer is used to produce polyamides, esters, or amines for applications in oilfield chemicals, coatings, lubricants, or corrosion inhibitors, these dimer derivatives have unique viscosity, surface activity, and flexibility properties, because of their underlying chemical structures. Depending on the specifics of the end-use application, these unique properties may lead to improved performance and value in use.
Kraton Corporation, represented by Univar, manufactures the TOFA-based UNIDYMETM dimer acids product line at its facility in Dover, Ohio. Kraton is backward integrated to TOFA, which means supply security for its dimer acids customers. When combined with Univar’s supply chain footprint in the US, UNIDYMETM dimer acids offer a powerful combination of performance, steady supply, and short lead times, from a domestic producer.
Take a closer look at some of the applications for UNIDYMETM dimer acids produced from TOFA:
- Oilfield Chemicals – Provide key viscosity and metal surface protection properties
- Coatings – Impart flexibility and durability properties to epoxy and polyester coatings
- Lubricants – Yield surface activity, viscosity, and lubricity properties in metalworking fluids and synthetic lubricants
- Corrosion inhibitors – Provide metal protection performance because of the underlying surface activity properties
