Description

Fatty Acids, Tall-Oil, Polymers With Benzoic Acid, Dipentaerythritol, Pentaerythritol And Phthalic Anhydride is a complex, high-performance synthetic resin derived from tall oil fatty acids and key polyfunctional monomers. This compound matters for its ability to provide excellent film formation, adhesion, and chemical resistance in demanding industrial coatings and adhesives. It is primarily needed by formulators in the paints & coatings, printing inks, and specialty adhesive industries seeking durable, high-gloss finishes. The product is supplied under CAS No. 68139-36-6.

Application

• High-Performance Industrial Coatings: Used as a key resin binder in alkyd formulations for machinery, agricultural equipment, and marine paints requiring durability and gloss.
• Printing Inks: Serves as a vehicle resin in offset and gravure inks, contributing to rapid drying, rub resistance, and excellent printability.
• Specialty Adhesives & Sealants: Imparts strong adhesion and flexibility in construction and automotive sealant formulations.
• Wood Finishes: A critical component in varnishes and wood stains, enhancing depth of color, water resistance, and protective film properties.
• Metal Primers: Used in corrosion-resistant primer systems to promote adhesion to metal substrates and provide a protective barrier.
• Overprint Varnishes: Provides a protective, high-gloss topcoat for packaging and printed materials.

Quality Control

Our production of this synthetic resin adheres to strict batch-to-batch consistency protocols to ensure reliable performance in your formulations. Quality is verified through tests for key parameters including acid value, viscosity, solids content, and color. A Certificate of Analysis (COA) detailing these specifications is 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, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to prevent skinning or thickening. Keep away from strong acids and organic solvents.
