Description

Resin Acids And Rosin Acids, Polymd., Esters With Glycerol is a specialized polymeric ester derived from the esterification of polymerized resin and rosin acids with glycerol. This compound is valued for its enhanced stability and film-forming properties compared to its base acid components, making it a crucial intermediate and performance additive. It is primarily sought after by manufacturers in the adhesives, coatings, printing inks, and polymer modification industries for its ability to improve tack, adhesion, and durability.

Application

• As a tackifier and adhesion promoter in hot-melt and pressure-sensitive adhesives.
• As a resin modifier and film-forming agent in protective coatings and industrial paints.
• As a viscosity modifier and gloss enhancer in printing inks and varnishes.
• As a processing aid and compatibilizer in polymer blends and rubber compounding.
• As a component in sealants and caulks to enhance flexibility and weather resistance.
• As a binder or sizing agent in paper and paperboard production.
