Description

Fatty Acids, Tall-Oil, Polymers With Glycerol, Isophthalic Acid, Linseed Oil, Maleic Anhydride, Rosin And Trimethylolpropane is a complex, high-performance alkyd resin intermediate designed for industrial coatings and adhesives. This specialized polymer delivers a unique balance of flexibility, adhesion, and chemical resistance critical for demanding applications. It is primarily sought by formulators in the protective coatings, printing inks, and adhesive industries seeking to enhance product durability and performance.

Application

• High-Performance Industrial Coatings: Formulation of air-drying and baking enamels for machinery, agricultural equipment, and metal substrates requiring excellent weather resistance and adhesion.
• Protective & Marine Coatings: Used in corrosion-resistant primers and topcoats for structural steel, bridges, and marine environments due to its robust film properties.
• Printing Inks: Serves as a resinous binder in specialty printing inks, contributing to gloss, rub resistance, and rapid setting properties.
• Adhesives & Sealants: A key component in structural and assembly adhesives, providing strong bonding strength and flexibility.
• Wood Finishes: Formulation of varnishes and stains that offer deep penetration, durability, and enhanced wood grain appearance.
• Modifying Agent for Polymers: Used to modify the properties of other polymers, improving flexibility, adhesion, or compatibility in composite systems.

Quality Control

Our production of this alkyd resin intermediate adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, color, and solids content to ensure it meets the precise requirements of coating formulators. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and performance reliability for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flames. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
