Description

Soybean Oil, Polymer With Pentaerythritol, Phthalic Anhydride And Trimethylolpropane CAS NO 66071-01-0 is a specialized alkyd resin derived from renewable soybean oil, modified with polyols and phthalic anhydride. This polymer is engineered to provide a versatile and durable film-forming component, offering an excellent balance of flexibility, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings and adhesives industries seeking sustainable, high-performance solutions.

Application

• Industrial and Protective Coatings: Used as a primary resin in air-drying and baking enamels for machinery, agricultural equipment, and metal substrates.
• Printing Inks: Serves as a binder in offset and lithographic inks, providing gloss, rub resistance, and good pigment wetting.
• Adhesives and Sealants: Acts as a key polymeric component to enhance flexibility, tack, and environmental durability.
• Wood Finishes: Formulated into varnishes and stains, offering good penetration and a protective, clear film.
• Primers: Provides excellent adhesion to various substrates and acts as a corrosion-inhibiting base coat.
• Architectural Coatings: Modified for use in decorative paints requiring good leveling and weatherability.
