Description

C(9)-Unsaturated Hydrocarbons, Polymers With Maleic Anhydride is a synthetic polymer derived from the reaction of C9 hydrocarbon streams with maleic anhydride. This versatile chemical intermediate is valued for its ability to impart specific functional properties, such as adhesion promotion, surface modification, and dispersancy, to final formulations. It is a critical component for manufacturers in the coatings, adhesives, ink, and polymer modification industries seeking to enhance product performance.

Application

• As a key raw material in the production of alkyd resins for industrial and decorative coatings.
• As a dispersing agent and grinding aid for pigments in printing inks and color concentrates.
• As an adhesion promoter and tackifier in pressure-sensitive and hot-melt adhesives.
• As a viscosity modifier and flow control agent in lubricant and fuel oil additives.
• As a surface sizing agent and wet-strength additive in paper and paperboard manufacturing.
• As a corrosion inhibitor intermediate for metalworking fluids and protective coatings.
• For the modification of thermoplastic polymers to improve compatibility and mechanical properties.
• In the synthesis of epoxy curing agents and other specialty chemical intermediates.
