Description

Menhaden Oil/Phthalic/Pentaerythritol/Ethylene Glycol CAS NO 67989-59-7 is a specialized alkyd resin intermediate, synthesized from the polycondensation of phthalic anhydride, pentaerythritol, and ethylene glycol, modified with menhaden oil. This compound is valued for its role in formulating high-performance, flexible, and durable surface coatings. It is primarily required by manufacturers in the paints, varnishes, and industrial coatings sectors seeking to enhance product longevity and environmental resistance.

Application

• Primary component in air-drying and baking alkyd resins for industrial and architectural paints.
• Modifier for corrosion-resistant coatings used on metal structures, machinery, and marine equipment.
• Binder in high-gloss enamels and varnishes for automotive and wood finishing applications.
• Raw material for printing inks, providing improved adhesion and film formation.
• Intermediate in the synthesis of plasticizers and adhesives for enhanced flexibility.
• Base for specialty coatings requiring good weathering and UV resistance.

Quality Control

Our alkyd resin intermediates undergo rigorous quality testing to ensure batch-to-batch consistency and performance in final formulations. Quality is monitored against key parameters including acid value, viscosity, and color. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Due to its nature as an organic resin intermediate and the provided property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term preservation of quality. Keep away from strong alkalis and incompatible organic solvents.
