Description

Tall Oil Fatty Acids-Isophthalic Acid-Pentaerythritol Polymer is a synthetic resin derived from renewable tall oil fatty acids, isophthalic acid, and pentaerythritol. This polymer is valued for its excellent film-forming properties, chemical resistance, and versatility as a binder or modifier. It is primarily needed by manufacturers in the coatings, adhesives, and ink industries seeking high-performance, sustainable raw materials. The compound is identified by CAS No. 67746-05-8.

Application

• Alkyd Resin Modifier: Used to enhance flexibility, drying time, and durability in industrial and decorative alkyd coatings.
• Corrosion-Resistant Coatings: Serves as a key binder in primers and topcoats for metal protection in marine, automotive, and structural applications.
• Adhesive Formulations: Imparts tack, strength, and water resistance in pressure-sensitive and structural adhesives.
• Printing Inks: Utilized as a resin vehicle to improve gloss, adhesion, and rub resistance in various ink systems.
• Industrial Maintenance Paints: A critical component in high-performance paints for factories, bridges, and infrastructure.
• Sealants and Caulks: Acts as a plasticizing and binding agent to ensure long-term elasticity and weather resistance.

Quality Control

Our Tall Oil Fatty Acids-Isophthalic Acid-Pentaerythritol Polymer is manufactured under a strict 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) documenting these specifications are available upon request.

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 containers tightly sealed when not in use to prevent skin formation or contamination.
