Description

Fatty Acids, Tall-Oil, Polymers With Ethylene Glycol, Glycerol, Pentaerythritol And Phthalic Anhydride is a complex polymeric resin derived from tall oil fatty acids, a renewable resource, and key polyols and acids. This product matters as a versatile, high-performance intermediate that offers excellent adhesion, flexibility, and chemical resistance for demanding industrial formulations. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for specialty ink and composite applications.

Application

• Alkyd Resins for Industrial Coatings: Serves as a key building block for air-drying and baking alkyd resins, providing excellent film formation, durability, and gloss for metal and wood coatings.
• Adhesive & Sealant Formulations: Imparts tack, flexibility, and adhesion to substrates in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives.
• Printing Inks: Used as a resinous component in specialty inks, including overprint varnishes and flexographic inks, to enhance gloss, rub resistance, and substrate adhesion.
• Elastomer Modification: Acts as a plasticizer or compatibilizer in rubber and elastomer compounds to improve processing and low-temperature flexibility.
• Composite Materials: Functions as a binder or sizing agent in fiber-reinforced plastics and other composite materials to improve interfacial bonding.
• Corrosion Inhibitive Primers: Formulated into primers where its film-forming properties contribute to barrier protection and adhesion to metal surfaces.

Quality Control

Our production of this polymeric resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, organic solvents, and sources of ignition. Due to its polymeric nature and potential for oxidation, prolonged storage at elevated temperatures should be avoided.
