Hydrogenated rosin triethylene glycol ester

Hydrogenated rosin triethylene glycol ester (CAS 68648-53-3) is a pale, thermally stable tackifier resin produced by esterifying hydrogenated rosin with triethylene glycol. Also marketed as Staybelite Ester 3.

Where is Hydrogenated rosin triethylene glycol ester used?

• Hot-melt and pressure-sensitive adhesives: improves tack and flexibility while maintaining bond performance across temperature ranges
• Printing inks: viscosity control and substrate adhesion in packaging
• Rubber, sealants and elastomeric compounds: softener improving processability and flexibility
• Polymer and plastic formulations: compatible plasticizing resin where low volatility is required
• Adhesive and coating formulations: plasticizer and rheology modifier where oxidative stability and colour retention matter
• It resists yellowing in the final product.

Good to know: Product specifications are commonly defined by softening point, acid value and colour on the Gardner scale. Store in a cool, dry environment to maintain chemical integrity and shelf life.

Commercial specifications

• Softening point, acid value and Gardner colour are typical specification parameters
• Kraft bags for solid form; heated ISO tanks or drums for liquid supply
