Maleic resin

OTHER NAME: Rosin modified maleic anhydride resin

DESCRIPTION

Maleic acid resin is a light yellow transparent solid obtained by using gum rosin as raw material, adding maleic anhydride, and esterifying with glycerol or pentaerythritol.

422# is produced by the addition reaction of rosin and maleic anhydride and esterification of glycerin;

424# is produced by the addition reaction of rosin and maleic anhydride and the esterification of pentaerythritol.

Features

Ø It has good miscibility with vegetable oils, easily soluble in aromatic hydrocarbon solvents, esters, ketones, turpentine, chlorinated hydrocarbons, etc., partially soluble in petroleum solvents, and insoluble in water and alcohol solvents.

Ø Light color, high softening point, excellent anti-aging properties, strong light resistance, not easy to yellow, and strong adhesion.

Ø It has good compatibility with nitrocellulose, and the paint film produced has high strength, high hardness, excellent brightness, polishability and fullness.
