Description

Soybean Oil, Polymer With Isophthalic Acid, Pentaerythritol And Trimethylolpropane CAS NO 68555-01-1 is a specialized alkyd resin derived from renewable soybean oil, modified with isophthalic acid and polyols. This engineered polymer is valued for its excellent film-forming properties, flexibility, and adhesion, offering a sustainable alternative to purely petrochemical-based resins. It is primarily sought after by manufacturers in the coatings, inks, and adhesive industries seeking to enhance product performance with bio-based content.

Application

• As a primary film-forming resin in industrial and architectural coatings.
• Formulation of high-performance printing inks for improved gloss and adhesion.
• Production of adhesives and sealants requiring good flexibility and bond strength.
• Manufacture of corrosion-resistant primers for metal substrates.
• Base component for wood finishes and varnishes.
• Use in flexible packaging coatings.
• Modifier for other polymeric systems to introduce bio-renewable content.
