Description

Fatty Acids, C14-18 And C16-22-Unsatd., Polymers With Diethylene Glycol, Glycerol And Phthalic Anhydride CAS NO 173832-47-8 is a specialized polymeric resin synthesized from unsaturated fatty acids, polyols, and phthalic anhydride. This compound is engineered to provide excellent film-forming, adhesion, and flexibility properties, making it a crucial intermediate for high-performance industrial coatings and inks. It is primarily sought after by formulators in the paint, varnish, and printing ink industries who require durable, flexible, and chemically resistant binder systems.

Application

• Alkyd Resin Modifier: Used as a reactive modifier or core component in the production of air-drying and stoving alkyd resins for industrial and decorative paints.
• Flexographic and Gravure Inks: Serves as a key binder resin, providing excellent pigment wetting, gloss, and adhesion to flexible substrates like films and foils.
• Protective Coatings: Formulated into corrosion-resistant primers and topcoats for metal substrates, leveraging its good water resistance and durability.
• Wood Finishes: Imparts flexibility and adhesion in varnishes and lacquers for furniture and flooring applications.
• Adhesive Formulations: Acts as a tackifying and film-forming agent in certain industrial adhesive systems.
• Overprint Varnishes: Used to create high-gloss, protective overprint coatings for packaging materials.

Quality Control

Our production of this polymeric resin adheres to strict batch-to-batch consistency protocols, ensuring reliable performance in your formulations. Quality is monitored through key parameters including acid value, viscosity, color, and solids content. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) in the headspace of partially used containers is recommended to preserve product integrity.
