Description

Soybean/Phthalic-Maleic Anhydride/Di-Pentaerythritol/Eg CAS NO 68122-69-0 is a specialized polymeric resin derived from soybean oil, phthalic anhydride, maleic anhydride, and di-pentaerythritol. This compound is engineered to provide a unique balance of flexibility, chemical resistance, and durability, making it a critical component in high-performance industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and specialty plastics industries seeking bio-based or enhanced-performance resin solutions.

Application

• As a primary resin or modifier in high-solids and solvent-borne industrial coatings for metal and wood substrates.
• Formulation of specialty adhesives and sealants requiring excellent adhesion and environmental resistance.
• Production of alkyd resins with improved drying properties and film hardness.
• As a cross-linking agent or polyol component in polyurethane systems for elastomers and coatings.
• Manufacture of printing inks where pigment wetting and gloss are critical.
• Component in composite materials and fiber-reinforced plastics.
• Base for bio-based polymers, contributing to sustainable product development.

Quality Control

Our Soybean/Phthalic-Maleic Anhydride/Di-Pentaerythritol/Eg is produced under a stringent quality management system. Each batch is tested against key parameters including acid value, viscosity, color, and solids content to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) detailing these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. Due to its nature as an organic resin, prolonged exposure to air and moisture should be minimized to prevent skin formation or viscosity changes.
