Description

Fatty Acids, Cottonseed-Oil, Polymers With Linseed-Oil Fatty Acids, Pentaerythritol, Phthalic Anhydride And Polyethylene Glycol CAS NO 128704-78-9 is a specialized alkyd resin intermediate, engineered through the polycondensation of natural and synthetic components to deliver a unique balance of properties. This product matters for formulators seeking to enhance the flexibility, adhesion, and drying characteristics of surface coatings and inks. It is primarily needed by manufacturers in the paints & coatings, printing inks, adhesive, and industrial resin sectors who require high-performance, tailored polymeric backbones.

Application

• Primary component in high-quality alkyd resins for industrial and decorative paints.
• Modifying agent in printing inks to improve gloss, flow, and substrate adhesion.
• Building block for specialty adhesives and sealants, providing enhanced flexibility and bond strength.
• Intermediate for corrosion-resistant primer formulations in automotive and marine coatings.
• Raw material for plasticizers and compatibilizers in polymer compounding.
• Base for wood finish resins, offering good penetration and durability.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Quality is monitored through key parameters including acid value, viscosity, color, and solids content. 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 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 moisture absorption.
