OTHER NAME: Maleic rosin

DESCRIPTION

Maleated rosin is a transparent solid resin made by vacuum treatment after the addition reaction of high-quality rosin and butenedioic anhydride. Also known as maleic acid rosin ester or maleic anhydride rosin.

Features

Ø Compared with rosin, it has higher acid value, softening point, antioxidant and aging resistance.

Ø The molecular structure has two more carboxyl groups than ordinary rosin, which enhances the activity of the carboxyl groups and has higher reactivity.

Ø When used as a sizing agent, its emulsion has good stability, high dispersion and utilization, and can effectively reduce the dosage of precipitating agents such as aluminum sulfate.

Ø Soluble in acetone, ethyl acetate, dichloroethane, insoluble in ethanol and solvent gasoline.
