Description

Abietic Acid CAS NO 17817-95-7 is a naturally occurring diterpenoid carboxylic acid and a primary constituent of rosin. This compound serves as a crucial industrial intermediate and functional additive valued for its chemical reactivity and hydrophobic properties. It is essential for manufacturers in the adhesives, coatings, printing inks, and polymer synthesis industries seeking to enhance product performance and develop sustainable, bio-based formulations.

Application

• Adhesives & Tackifiers: A key raw material for modifying rosin esters, which are fundamental tackifiers in pressure-sensitive adhesives, hot-melt adhesives, and sealants.
• Coatings & Inks: Used in the synthesis of resins for protective coatings, varnishes, and printing inks, where it improves gloss, hardness, and drying properties.
• Polymer Industry: Acts as a monomer or modifier in the production of synthetic resins, polyesters, and plasticizers.
• Soaps & Surfactants: Employed in the manufacture of disproportionated rosin soaps for the synthetic rubber (SBR) industry and in various emulsifying agents.
• Fluxes: A critical component in rosin-based solder fluxes for electronics assembly, facilitating solder flow and preventing oxidation.
• Pharmaceutical Intermediates: Serves as a starting material or chiral building block for the synthesis of certain pharmaceuticals and bioactive compounds.
