Rosin X

Rosin X (CAS 85026-55-7) is a modified rosin derivative used as a plasticizer, softener, and surface modification agent in rubber processing and specialty coatings.

Where is Rosin X used?

• Rubber and tire manufacturing: processing aid and softener that improves compound workability and tack during mixing and calendering
• Textile and leather finishing: modifies surface wetting behaviour for uniform coating adhesion and penetration into fibrous substrates
• Paper and packaging: supports sizing and surface treatment where controlled hydrophobicity and resin compatibility are required
• Printing inks: resin modifier that adjusts viscosity, adhesion, and film-forming characteristics in solvent-based and oil-based systems
• It bridges the functional gap between conventional rosin and fully synthetic alternatives.

Good to know: Buyers should confirm softening point, acid value, and purity specifications directly with the supplier before use.
