Description
A reactive, white solid compound that is used in the manufacture of polyester and alkyd resins. Maleic anhydride has needle-like crystals that dissolve readily in water to form Maleic acid. It is also used in finishing processes for Paper and Permanent press textiles. Maleic acid is also used in alkyd resins to increase hardness and decrease yellowing in baking enamels (Brady 1971).
