Ester of rosin


Ester of rosin is a polyol ester of rosin acid. Commonly used polyols are glycerol and pentaerythritol. Polyol rosin ester is a light yellow transparent solid with softening point of 90 ~ 110℃ and acid value of 10 ~ 20. If it is applied to paint manufacture, the quality of the paint is slightly higher than that of rosin calcium soap. The softening point of pentaerythritol rosin ester is higher than that of glycerin rosin ester, the drying performance after making varnish, hardness, water resistance and other properties are better than that of glycerin rosin ester. Such as the use of polymerized rosin or hydrogenated rosin as raw materials made of the corresponding ester, discolouration tendency decreased, other properties have been improved. The softening point of polymerized rosin ester was higher than that of hydrogenated rosin ester.
