Description

Soybean Oil, Polymer With Pentaerythritol, Phthalic Anhydride And 2,4-Tdi CAS NO 127279-04-3 is a specialized alkyd-type polymer resin derived from modified soybean oil. This compound is engineered to provide a unique balance of flexibility, adhesion, and chemical resistance, making it a valuable intermediate for high-performance coatings. It is primarily utilized by formulators in the paints, inks, and industrial sealants industries seeking bio-based or modified resin components. The product offers a versatile chemical backbone for creating durable and sustainable protective finishes.

Application

• Industrial and Protective Coatings: As a key resin component in formulations for metal primers, machinery enamels, and corrosion-resistant paints.
• Flexible Inks and Overprint Varnishes: Used in specialty printing inks and varnishes requiring good adhesion and flexibility on various substrates.
• Adhesive and Sealant Systems: Serves as a polymeric modifier to enhance the toughness and weather resistance of construction and automotive sealants.
• Wood Finishes: Incorporated into stains and varnishes to improve penetration, durability, and dry time.
• Plastic and Rubber Coatings: Provides a compatible resin base for coatings on plastic and elastomeric surfaces.
• Marine and Anti-fouling Coatings: Used in coating systems where hydrolytic stability and adhesion in humid environments are critical.

Quality Control

Our production of Soybean Oil, Polymer With Pentaerythritol, Phthalic Anhydride And 2,4-Tdi adheres to stringent quality management protocols. Each batch is tested against critical parameters including viscosity, acid value, hydroxyl value, and solids content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are available upon request. Our quality system is designed to support formulations requiring compliance with various industrial and environmental standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat, open flames, and incompatible materials such as strong acids and organic solvents. Under these conditions, the product is typically stable for 24 months from the date of manufacture. Always refer to the Safety Data Sheet (SDS) for complete handling and storage instructions.
