Description

Hydroabietyl Alcohol CAS NO 26266-77-3 is a high-purity, hydrogenated derivative of rosin, specifically a diterpene alcohol derived from abiotic acid. This compound serves as a versatile, non-crystallizing tackifier and modifier, prized for its excellent color stability, low odor, and resistance to oxidation and UV degradation. It is an essential raw material for formulators in the adhesives, coatings, and polymer industries seeking to enhance performance and longevity.

Application

• Adhesive Formulations: Acts as a key tackifier and plasticizer in hot-melt, pressure-sensitive, and solvent-based adhesives, improving bond strength and flexibility.
• Coatings and Inks: Used as a resin modifier in protective coatings, printing inks, and varnishes to enhance gloss, adhesion, and water resistance.
• Polymer Modification: Functions as a processing aid and compatibilizer in rubber and various thermoplastic compounds to improve flow properties and mechanical characteristics.
• Personal Care Products: Employed as a film-forming agent and viscosity modifier in hair sprays, nail polishes, and other cosmetic formulations.
• Sealants and Caulks: Imparts permanent tack and improves the cohesive strength of non-drying and elastic sealants.
• Industrial Additives: Serves as a dispersing agent, corrosion inhibitor, or intermediate in the synthesis of esters for lubricants and other specialty chemicals.
