Description

Fatty Acids, C16 And C18-Unsatd., Polymers With p-tert-Butylbenzoic Acid, Peanut-Oil Fatty Acids, Pentaerythritol And Phthalic Anhydride is a specialized polymeric alkyd resin intermediate designed for high-performance coating formulations. This compound matters because it offers a unique balance of flexibility, adhesion, and chemical resistance derived from its complex structure of unsaturated fatty acids, aromatic acids, and polyols. Industrial manufacturers in the paints, coatings, inks, and adhesive sectors need it to develop durable, protective finishes for metal, wood, and plastic substrates.

Application

• High-performance industrial and marine coatings requiring excellent weather and corrosion resistance.
• Baking enamels and stoving finishes for automotive parts, appliances, and metal furniture.
• Modifying agent in air-drying alkyd resins to improve drying time, film hardness, and gloss.
• Base resin for specialty printing inks, contributing to pigment wetting and substrate adhesion.
• Component in adhesive and sealant formulations to enhance flexibility and bonding strength.
• Protective primers and undercoats for architectural and maintenance paints.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards for resin intermediates. Key parameters such as acid value, viscosity, color, and solids content are monitored. Certificates of Analysis (COA) are available upon request to support your formulation and quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent skinning or changes in viscosity.
