Abietic acid

Abietic acid (CAS 514-10-3), also known commercially as Sylvic acid, is the primary resin acid derived from pine rosin; a foundational raw material for adhesives, coatings and surface treatment.

Where is Abietic acid used?

• Adhesives and sealants: builds tack and cohesive strength
• Pressure-sensitive and hot-melt formulations
• Printing inks: resin component controlling viscosity, pigment dispersion and adhesion to paper and packaging
• Surface coatings: film formation and wetting agent improving substrate coverage in alkyd and varnish systems
• Cosmetic bases: texture modification
• It also functions as a tackifier, emulsifier and film-forming agent.

Good to know: Rosin-derived grades vary in purity and acid value; buyers should confirm specification sheets against their formulation requirements.
