Description

Tallow Oil Fatty Acids, Phthalic Anhydride, Pentaerythritol, Ethylene Glycol Polymer is a specialized alkyd resin intermediate or polyester polyol, synthesized from a blend of natural and synthetic raw materials. This compound is valued for its ability to impart flexibility, adhesion, and specific rheological properties to final polymer formulations. It is primarily required by manufacturers in the coatings, adhesives, and resin industries seeking to modify product performance.

Application

• As a flexibilizing agent and adhesion promoter in alkyd resin formulations for industrial and decorative coatings.
• Key intermediate in the production of air-drying and baking enamels, providing improved film formation and durability.
• Modifier for polyurethane adhesives and sealants to enhance elasticity and substrate wetting.
• Building block for saturated polyester resins used in coil coatings and can linings.
• Raw material for manufacturing plasticizers and lubricant additives.
• Component in printing ink vehicles to adjust viscosity and gloss.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters such as acid value, hydroxyl value, viscosity, and color are strictly monitored. Certificates of Analysis (COA) 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 incompatible materials such as strong acids and organic solvents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent moisture absorption and skin formation.
