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.
