Description

Soybean Oil, Polymer With Benzoic Acid, Isophthalic Acid, Pentaerythritol And Trimethylylolethane CAS NO 125643-63-2 is a specialized alkyd resin derived from renewable soybean oil and a blend of polybasic acids and polyols. This compound matters for its ability to provide a unique balance of flexibility, adhesion, and chemical resistance in formulated coatings. Industrial manufacturers in the paints, coatings, inks, and adhesive sectors require this polymer to develop high-performance, sustainable products.

Application

• Industrial and Protective Coatings: As a primary resin binder in metal primers, machinery enamels, and corrosion-resistant finishes.
• Architectural Paints: Formulation of durable, low-VOC interior and exterior house paints with excellent gloss and flow.
• Printing Inks: Used in solvent-based and overprint varnishes to enhance gloss, rub resistance, and drying properties.
• Adhesives and Sealants: Serves as a tackifying and film-forming agent to improve bond strength and flexibility.
• Wood Finishes: Key component in varnishes and lacquers for furniture and flooring, offering good penetration and durability.
• Specialty Resins: Intermediate for further chemical modification to create custom polymers with targeted properties.
