Description

Soybean Oil, Polymer With Maleic Anhydride, Pentaerythritol, Phthalic Anhydride And Trimethylolpropane CAS NO 68038-48-2 is a specialized alkyd resin intermediate derived from renewable soybean oil. This modified polymer is engineered to impart enhanced flexibility, adhesion, and durability to final coating formulations. It is a critical raw material for manufacturers in the paints, coatings, inks, and adhesive industries seeking to improve product performance with bio-based components.

Application

• Alkyd Resin Production: Primary component for manufacturing high-quality, flexible alkyd resins used in industrial and decorative paints.
• Protective Coatings: Formulation of corrosion-resistant primers and topcoats for metal substrates, including machinery and structural steel.
• Printing Inks: Used as a binder in offset and lithographic inks to enhance gloss, adhesion, and drying properties.
• Adhesives & Sealants: Imparts tack and flexibility in pressure-sensitive adhesives and construction sealants.
• Wood Finishes: Key ingredient in varnishes and wood stains, offering good penetration and a durable protective film.
• Plasticizers & Modifiers: Acts as a polymeric plasticizer or modifier to improve the impact resistance and flexibility of other resin systems.
