Rosin Pentaerythritol Ester

Product Name

Rosin Acids, penta rosin ester, maleic rosin, rosin pentaerythritol ester

Chemical Properties

Rosin Ester is a white crystalline powder that is soluble in ethanol, glycerol, ethylene glycol, and formamide but insoluble in acetone, benzene, carbon tetrachloride, ether, and petroleum ether. It is the product of esterification of modified rosin, which has a higher softening point than PERE. Maleic Rosin is known for its water-resistance, durability, and brightness, making it a valuable addition to industries such as adhesives, paint, inks, stencil, and electronic applications.
