Description

Fatty Acids, C16-18 And C18-Unsatd., Polymers With p-tert-Butylphenol, Formaldehyde, Glycerol, Phthalic Anhydride, Rosin And Tung Oil is a specialized polymeric resin derived from a complex formulation of fatty acids, rosin, and other key monomers. This product is engineered to deliver a unique balance of properties, making it a critical component in high-performance industrial coatings and inks. Manufacturers in the surface coatings, printing, and adhesive industries rely on this tailored resin for its ability to enhance film formation, adhesion, and durability.

Application

• High-Performance Industrial Coatings: Serves as a key film-forming resin in protective coatings for metal, wood, and plastic substrates, offering excellent weather resistance and gloss.
• Printing Inks: Used as a binder and tackifier in specialty printing inks, including gravure and flexographic inks, providing good pigment wetting and printability.
• Adhesives and Sealants: Functions as a tackifying resin in hot-melt and pressure-sensitive adhesive formulations, improving initial tack and bond strength.
• Overprint Varnishes: Imparts a durable, protective, and glossy finish to printed materials and packaging.
• Marine and Corrosion-Resistant Coatings: Contributes to the formulation of coatings designed for harsh environmental exposure due to its polymerized oil components.
• Modifier for Alkyd Resins: Used to modify conventional alkyd resins, enhancing drying time, hardness, and chemical resistance.

Quality Control

Our production of this specialty 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 softening point are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all 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, and well-ventilated area away from 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 changes in viscosity.
