Description

Neoabietic Acid CAS NO 471-77-2 is a diterpenoid resin acid, a key constituent of rosin and a significant isomer of abietic acid. This compound is valued for its role as a chemical intermediate and its contribution to the properties of rosin-based derivatives in industrial formulations. It is primarily required by manufacturers in the chemical synthesis, adhesives, coatings, and ink industries for producing tackifiers, esters, and other specialty chemicals.

Application

• Chemical intermediate for the synthesis of rosin esters and other derivatives.
• Key component in the formulation of tackifiers for pressure-sensitive and hot-melt adhesives.
• Used in the production of printing inks to modify rheology and adhesion properties.
• Employed in coating formulations to enhance film hardness and water resistance.
• Starting material for the manufacture of metal resinates used as driers in paints and varnishes.
• Research and development of pharmaceuticals and agrochemicals due to its bioactive diterpene structure.
