Overview
Methyl hydrogenated rosinate (CAS 8050-15-5 ) is a hydrogenated rosin methyl ester used as a plasticizer, tackifier modifier, and rheology agent across adhesive, coating, and rubber applications.
Its hydrogenated structure provides improved color stability and oxidative resistance compared to standard rosin esters, which directly affects shelf life and end-product appearance.
In pressure-sensitive adhesives and hot-melt formulations, it functions as a plasticizer that improves tack, flexibility, and substrate wetting without compromising bond strength.
Printing ink manufacturers use it to control viscosity and flow in solvent-based and offset ink systems, improving printability on film and paper substrates.
In rubber compounding, it acts as a softener that aids processing and improves the dispersion of fillers and pigments during the manufacturing process.
Coating formulators incorporate it into lacquers and surface coatings where controlled film flexibility and gloss retention are required for high-quality finishes.
Methyl hydrogenated rosinate is supplied as a pale, viscous liquid at ambient temperature and is available in technical grade for various industrial uses.
Specifications are typically defined by acid value, color on the Gardner scale, and viscosity, with bulk liquid and drum packaging as standard supply formats.
