Description

Coconut Oil/Phthalic/Pentaerythritol/Propylene Glycol CAS NO 67989-68-8 is a specialized alkyd resin intermediate, a co-ester formed from the reaction of coconut oil fatty acids, phthalic anhydride, pentaerythritol, and propylene glycol. This compound is a critical building block for formulating high-performance, fast-drying alkyd resins used in industrial coatings. It is essential for manufacturers seeking to produce coatings with excellent durability, gloss retention, and chemical resistance for demanding environments. Key industries that rely on this intermediate include the paints and coatings, automotive refinish, and industrial maintenance sectors.

Application

• Primary raw material for short-oil alkyd resin synthesis, enabling fast-drying coating formulations.
• Binder component in industrial air-dry and force-dry coatings for machinery, agricultural equipment, and metal substrates.
• Key intermediate for high-gloss enamel paints, providing superior flow and leveling properties.
• Formulation of chemical-resistant coatings for use in mildly corrosive environments.
• Base for automotive refinish primers and topcoats, offering a balance of hardness and flexibility.
• Component in maintenance paints for structural steel, bridges, and outdoor installations.

Quality Control

Our production of this alkyd intermediate adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, color, and non-volatile content to ensure it meets the precise requirements for downstream resin manufacturing. Certificates of Analysis (COA) detailing these specifications are available for every shipment upon request, providing full traceability and quality assurance for your formulation process.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and skin formation.
