Maleic anhydride (MLA) appears as colorless crystalline needles, flakes, pellets, rods, briquettes, lumps or a fused mass. Used to make paints and plastics and other chemicals. Maleic anhydride is a cyclic dicarboxylic anhydride that is the cyclic anhydride of maleic acid. It has a role as an allergen. It is a cyclic dicarboxylic anhydride and a member of furans.
Maleic anhydride is used in the synthesis of unsaturated polyester resins and as a reactant in synthesizing important products such as agricultural chemicals, lubricant additives and food acidulatents.

Maleic Anhydride
Curing properties are those obtained using 2% Cobalt Octoate (1% cobalt metal) & 2% MEK Peroxide (M50) in 100 grams of resin previously stabilized at 25°C.
Storage: In Drums/ IBC’s: Product should be kept in temperature below 25°C. Direct heat sources such as sun light must be avoided as it decreases product’s shelf life. drums or tanks should be kept well sealed to avoid moisture or monomer loss.
