Description

Fatty Acids, Tall-Oil, Polymers With Diethylene Glycol, Maleic Anhydride And Phthalic Anhydride CAS NO 68071-68-1 is a specialized polymeric resin derived from tall oil fatty acids, a renewable resource, and key monomers. This compound is engineered to provide excellent film-forming properties, adhesion, and chemical resistance, making it a versatile intermediate for high-performance coatings and adhesives. It is essential for formulators in the paint, ink, and industrial adhesive sectors seeking to enhance product durability and performance with sustainable raw materials.

Application

• Alkyd Resin Modifier: Used as a reactive intermediate to improve flexibility, drying time, and gloss in air-drying alkyd resins for industrial and decorative paints.
• Corrosion-Resistant Coatings: A key component in primer and topcoat formulations for metal substrates, offering enhanced barrier protection and adhesion.
• Printing Inks: Imparts excellent pigment wetting, flow, and film integrity for various printing ink applications, including overprint varnishes.
• Industrial Adhesives & Sealants: Functions as a tackifier and binder, improving cohesive strength and environmental resistance in adhesive formulations.
• Wood Finishes: Used in varnishes and stains to provide durable, protective films with good penetration and water resistance.
• Plasticizer & Compatibilizer: Acts as a secondary plasticizer and compatibilizing agent in polymer blends and composite materials.

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/59-77°F). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat sources and open flames. For long-term storage, consider blanketing with an inert gas such as nitrogen to minimize oxidation.
